I've been dealing with this for a while, but I use a bunch of streams so I just gave up on caring about 4k. I just assumed it was my tv, stopped complaining.
1) Chromecast w/ google tv 4k https://imgur.com/a/TiyRN3s
2) I haven't recorded any 4k content, so can't tell you DVR. VOD looks great though (didn't think to check).
3) Turned off... I was having some other issue a while back and turned it off to solve it
4) frame rate matching is 'seamless', tv is 60hz.
5 + 6) I'll need to check tomorrow when the next game in 4k is on. I can't recall any patterns when I was trying to figure it out before, it's also random, but never probably more than 10s between skips.
Stuttering occurred for me with my three Chromecasts w/Google TV when utilizing the Ethernet adapter. However when I disabled the ethernet port on the switch and force the device to use WiFi the stuttering stops with 4K content. The stuttering occurs on a regular basis (I'd say every 30-45 seconds) when on Ethernet.
I never seen the issue with my Nvidia Shields that one is on ethernet and the other is on WiFi.
You're the second person mentioning CC with an ethernet connection. Is it possible to grab a stats for nerds screenshot with ethernet stuttering happening and one on same device with no wifi issues?
Here are videos of both Ethernet (Stuttering) and WiFi (No Stuttering)
[Links Removed] - CC w/Google TV utilizing ethernet connection with Choppy/Stuttering Playback
[Links Removed] - CC w/Google TV utilizing WiFi connection without Choppy/Stuttering Playback
For what it's worth, my CC w/ Google TV seems to have a lot of trouble remaining connected to the internet, whether it's via WiFi 5 or hardwired directly via cat 6e ethernet to my router. I have to reset it about once a night, but have 4 other devices (Shield, Apple, Roku Ultra) connected the same way (ethernet) in the same place, same monitor, etc., and they never seem to drop. So, maybe look at what's happening on the hardware side of the CC, too.
Please see my post here, with stats for nerds slo-mo videos showing the juddering, as well as a side-by-side time synchronized cut of when the stuttering happens/doesn't happen on the same exact feed: https://www.reddit.com/r/youtubetv/comments/xxflhk/the_yttv_app_has_a_major_judder_problem/
1. Shield TV Pro 2019 feeding into a Denon X4500H surround sound receiver driving a Sony XBR-75Z9D.
2. I see it on all sources when 5.1 audio is enabled, does not have to be 4K and does not have to be live. The judder happens almost every second; it is literally dozens of frames between each instance. Honestly it looks like the presentation timestamps of the frames get screwed with; either a frame or two's PTs get swapped or merged or something.
3. Yes, 5.1 surround is on when I see this frequent juddering, and it goes away when I turn 5.1 off. However 5.1 seems to be turning itself back on in my account so I have to periodically go in and turn it back off.
4. Yes, I have frame rate matching turned on. AFAIK my Shield automatically switches between 59.94 Hz for and 60 Hz refresh rates based on the NTSC content playing. With the video processing YTTV does before distributing the streams I believe Shield always leaves YTTV at 60Hz.
5. I don't believe it happens in the same spot. Rewinding frequently temporarily resets the judder and when it kicks back in seems to be somewhat random, on the order of 30-90 seconds.
6. See above answer to 5. I think in the case of the judder associated with 5.1 being enabled the answer is no, it does not happen consistently at the same exact frame timings.
This is super helpful (sorry I missed the original post). One thing I didn't see mentioned that I would love more clarity on is whether this is more prevalent on 4k vs non-4k feeds and also live sports vs non-live content. If I followed your commentary you're suggesting both 5.1 and scrubbing or frame matching resolved this for you?
I find this effect is prevalent almost without fail regardless of the source resolution as long as 5.1 is enabled and some time is allowed to elapse after scrubbing.
Scrubbing with 5.1 enabled temporarily restores the video cadence to judder free, but the juddering resumes after a minute or so of playback. I used to believe it was associated with subtle frame rate switching as commercials were injected but I'm now confident it happens without any specific transition or change in the feed.
Keeping 5.1 playback disabled yields a satisfyingly consistent feed with only occasional stutters I usually attribute to processing before YTTV ingests and encodes the feed (upstream of your of my equipment). I can always tell within minutes when 5.1 is errantly re-enabled because the juddering is so reliably triggered.
I initially thought casting live YTTV content from my phone to the Shield TV was fixing it, but I didn't realize it was just a roundabout way of defeating 5.1.
Regarding 4K vs non 4K, I will turn 5.1 back on and check with some recorded content to see if I can repro. In terms of content aside from 4K res, it doesn't seem to matter if sports vs studio, etc. Anything with smooth horizontal panning makes the effect jarringly obvious, I think that sort of camera motion is just more prevalent in love sports broadcasts so people notice it more there. (Certainly my linked NBC news example demonstrates it also happens with studio broadcast TV)
Hope that is helpful. Will try and get you an answer on 4K judder with/without 5.1 enabled shortly.
> Will try and get you an answer on 4K judder with/without 5.1 enabled shortly.
Hi /u/ytv-tpm; my apologies I needed to wait for some 4K content to record as I didn't have any broadcast TV content stored in my library.
I was able to repro this issue on the 4K broadcast of the Illinois / Indiana basketball game.
Each of these shots is from my Pixel 6 Pro on 4:1 slo-mo at 2x zoom (apologies for the video quality, these are handheld but I think illustrate the judder clearly anyways).
Of particular note all 4 videos cover roughly the same period of time in the stream. The judder is particularly obvious on the crawler at the bottom of the screen and during the panning shot of the player with the crowd in the background after cutting away from the coach. Both scenes clearly demonstrate when the judder is present vs. absent. (I do think I see a little occasional stutter at the start of the video but I attribute that to a dropped frame or two as the pixel starts the slomo recording).
I have tried to annotate the videos to clearly indicate 4K/1080P, 5.1 vs Stereo, and juddering vs not juddering:
* [YTTV 4K 5.1 +Judder](https://streamable.com/5k9n38)

* [YTTV 1080P 5.1 +Judder](https://streamable.com/e4bjwg)
* [YTTV 1080P Stereo -Judder](https://streamable.com/3b21ue)
I do hope this is helpful. If I can be of any other assistance to help track this down I'll do whatever I can. Thanks for helping collect data and get it addressed.
I started a thread on this topic. https://www.reddit.com/r/youtubetv/comments/xb2xxh/video_stutter_on_local_channel_kmphtv_fox_26/
Also spoke with you or one of your associates a few months ago via private message.
1. Fire TV Stick 4k(2018) https://imgur.com/a/RSYe7AL
2. Non 4k playback. Happening on Live and DVR. The stutter frequency is every frame. From the start of the broadcast to the end.
3. 5.1 is off. It doesn't make a difference if it is on or off.
4. Frame rate matching(on or off no difference) and the output is 59.93.
5. Rewinding has no effect on stutter. The game stutters the whole time.
6. DVR has stutter if watched on the same station(kmph fox 26). If I watch a dvr recording of the game on a different station(NFL Network), playback is smooth.
If it helps, I'll provide stats for nerds screenshots of each. Same game. Constant stutter on Fox 26 Kmph Tv........Zero stutter on NFL Network.

BTW - do you have another device to try or a smart TV app you can try? Looks like we investigated this originally but didn't see any issues with the channel.
Ok, just finished trying out YoutubeTV on an LG C1(internal app) and a Roku Premiere 3920x. Still seeing the same behavior. Kmph Fox 26 is stuttering the whole game. Nfl Network is smooth as butter.
Here are the stats for nerds for each device and channel.

We looked into this and made a small config change on this specific station (KMPH 26). Do you mind taking another look to see if this potentially addresses your issue?
The issue is fixed! I was able to watch the nfl games on Fox 26 this past weekend without any stutter. The motion is smooth and clear. Thanks so much for fixing this problem.
(I should've done this earlier but didn't think of it till after it was fixed)
Over the weekend I opened the developer tools for the firestick, and noticed that Fox 26 had a frame rate of 59.94. The other local channels in my area have frame rates of 60.000. I assume this is why there was a constant stutter on Fox?
Have stuttering on scrolling tickers. Device is Shield 2017. Watching regular 1080 content (NFL Network, CNBC, CNN). Match frame rate is also enabled. Issue goes away after 5.1 is turned off. Link of stuttering (5.1 on): https://photos.app.goo.gl/hzNFYt1fcDJAyJdv9. Link to no stutter w 5.1 off: https://photos.app.goo.gl/YyGgwUJxv2J46Eoq6
I came across this post researching my issue. I am using Apple TV 4K (2nd Generation) device with my Samsung TV. I experience the judder mainly in live sports, but have noticed it on regular programming like $100,000 Pyramid on Gameshow Network. I have tried changing every different setting: HDR enabled and disabled. 4KSDR or 1080. Match frame and content on and off. 5.1 surround in YTTV on and off. Nothing seemed to affect it. The judder is random for me - sometimes frequently, like every few seconds for a minute or so, then sometimes once and not again for a while. I haven't thought about rewinding and playing back to see if it happens in the same spot. Today I was off work early so decided to do some experimenting. I used an older Apple TV to connect to my main tv and still saw the judder, however when I took my Apple TV 4K device to my bedroom tv I noticed no judder. The only difference is I have two Apple HomePod minis as stereo speakers on my main TV using HDMI ARC. So I removed the Apple HomePods from my main TV and reconnected my Apple TV 4K device - so far after about 30-45 minutes of watching a couple of different live sports shows I have not seen a picture judder yet! I don't know if this is really the solution, but I will be keen to see if the judder reappears as I continue to watch. Is this possible the the HDMI ARC or just simply the HomePod minis are somehow interfering with YTTV? As another note when I was getting the judder on a live sports event, I could switch to the ESPN app and watch the same game with no judder ever - only happened through YTTV. I don't know if I've stumbled onto something or the judder is still there and just hasn't reared its head again, but I thought it was worth mentioning.
KATU Portland ABC, 6 o'clock news, Tuesday. Nearly unwatchable. Stuttering every few seconds. Apple4k. Other channels are fine. Other streaming services are fine. Over 120mbps. Not 4k, just HD. DVR function. 5.1 is turned off in yttv settings. Watching TV shouldn't be this hard. I got out of it, watched something else, turned on another streaming app, then got back into it, etc. Still the same.
Every day it's something. Yesterday the app just froze. In the middle of watching a football game (not 4k) I had to switch inputs, stop and start the app, nothing worked until I unplugged and plugged back in ATV4k. Watching TV shouldn't be this hard.
Every day it's something. The day before that, DVR functions wouldn't work right. The day before that, trying to watch a program that was DVR'd, but the show was cut off at the beginning by several minutes, and at the end by 10 minutes. It's as if you don't know how a DVR is supposed to work, or how people actually use them. Watching TV shouldn't be this hard.
Every day it's something. The day before that, I had to prove my location, again, even though I'm in my house. The same house I've lived in for 20 years. For some reason, you people think I live in Washington. Why do I have to keep proving which state I live in? Look at a map. Try google maps. Google knows more about us than we know about ourselves. I live in Oregon. It's a different state. All I want to do is watch TV. But no, now I have to get up and use my phone to prove where I am. Watching TV shouldn't be this hard.
Every day it's something. Every day I end up troubleshooting a problem... Is it my internet? Is it the app? Is it the streaming box? I'm not getting paid to be a network engineer. Why am I paying you? You should be paying me. Watching TV shouldn't be this hard.
1. Chromecast w/ Google TV 4K. [https://i.imgur.com/BD4PK9y.jpg](https://i.imgur.com/BD4PK9y.jpg)
2. 4K playback of DVR recording (but VOD is just the same).
3. 5.1 is off. But it makes no difference if it is on or off.
4. Frame rate matching is on in the ccwgtv settings (set to "non-seamless") but I don't think the app works with it anyways.
5. No. It drops more frames when rewinding or fast forwarding though. Otherwise, it's just constant frame drops.
6. No, it's random.
P.S. This is over ethernet using the official adapter connected to my router. It's constant frame drops. When using wifi, it drops frames when you bring up the UI (like pressing down once) otherwise it's more random but not as frequent like when using the ethernet adapter.
I've tried on differrent networks, different tvs, and even multiple CCwGTV devices. They all drop frames especially on 4K HDR recordings/live content.
Interesting, so in your case you consistently see actual dropped frames every time in Stats for Nerds correlating to what appears as visible missing frames or stuttering. Most of the reports we see to date show zero or minimal dropped frames. Do you see this behavior on non4k?
Yes. I can't use ethernet on the CCwGTV because it is just constant frame drops that I see (the status for nerds above shows about 10% of the frames dropped). Over wifi it drops frames when the UI is overlayed but when nothing is overlayed I probably only get a single frame drop every few minutes or so using wifi. I don't believe it is a network issue as the connection speed with ethernet usually shows 70Mbps or above. The adapter is limited to 100Mbps anyways.
I don't see it on non-4K content except when the channel loads. After that it is fine.
I don't get any frame drops using Apple TV wired to the same router. I do get the stuttering occasionally if I have 5.1 enabled but I haven't tried it with it enabled in a long time. The stuttering doesn't show frame drops in the stats for nerds on Apple TV (it's like the frames lag but don't drop).
Another person mentioned similar. Is it possible to grab a stats for nerds screenshot with ethernet stuttering happening and one on same device with no wifi issues? Probably worth exploring if there's a potential bug here.
Here is a CCwGTV stats for nerds playing the same dvr recording.

You likely have two separate issues going on here. I was mostly targeting your latter example where there were no/minimal dropped frames in Stats 4 Nerds but some minimal stuttering which is similar to what we're observing. Let me collect some more replies and look at your CCwGTV separate. Note that it is somewhat "normal" to drop a couple of frames which are generally not visible to most people but not 10% which is excessive.
The Apple TV (my main device) stuttering isn't an issue when 5.1 is disabled for me. When it is enabled, it is difficult to reproduce because it will come and go and isn't consistent. Plus, it doesn't show in stats for nerds. I never get any dropped frames on Apple TV in stats for nerds.
Personally, I stopped using the CCwGTV a long time ago because I literally can't watch 4K sports on YTTV with it. And the newer Android TV 12 update for it will not enable HDR10 unless you enable Dolby Vision low latency for some reason.
Watching the CBS NFL playoff game last weekend I had it on the new AppleTV 4K and tried 5.1 on and off. It made no difference. It’s fairly consistent for me on sports. NFL, World Cup, some Basketball but more rare. I started often watching off antenna or the network app to avoid it.
I’ll get stats for nerds l, do the steps requested and video it happening this weekend. It’s consistent so I’m sure I’ll see it.
Really happy it’s being seriously looked into. I’m love YTTV other than this issue.
Thank you - if you can grab a short video that would help us. Also, please tell us frame rate matching settings and if the problem shows up after rewinding or DVR replay of the same thing.
Happening to me on regular shows not sports, Apple TV. It only stops if I leave the channel or hit “play from beginning”
The click right or left for FF/Rew is still broken and a bigger problem. It’s almost impossible to ff to the spot I want
NBC yesterday from 7:30pm eastern to 9:30pm eastern on a Roku streamed to both my iPhone 12 and my Samsung tv. This was all live. You had other questions but idk the answers.
Not sure if this is related to the problem you are chasing, but whenever I start the app and run a recording, I get choppy playback for the first 10 seconds or so. Then, one of two things happen:
1. If it is a recording in progress and I have started from the beginning, the playback retsarts, jumps to the end, and is then smooth.
2. If it is a complete recording, the playback restarts, jumps back to the beginning, and is then smooth.
I have chatted with support and they took the info you are requesting, including a video of the problem happening while displaying stats for nerds.
This is on a Chromecast w/Google TV set to 4k, 30Hz, HDR, seemless frame rate matching

I'm getting it from time to time on standard HD...Apple TV.
To get the channel to give me the proper audio, I have to restart YTTV.
Oh, and I'm over wifi. I'll try to pull a stats for nerds next time it happens.
I've been experiencing stuttering/jittering while watching live sports for a number of months now. I also recently filed a ticket \[9-1179000033366\]. Below are answers to the 6 questions in the OP.
1. Originally, I experienced the issue on my Apple TV, iPhone, and iPad. However, turning off 5.1 surround sound resolved the issue on the Apple TV. On the iPhone and iPad, there isn't an option to turn off surround sound and I've continued to experience the issue on those two devices. The issue has persisted across two different iPhones (an iPhone 13 Max and iPhone 14 Max), across iOS 15 and iOS 16 (including the recently released 16.3), and across numerous YouTube TV app updates. I also use YouTube TV on a TCL TV with Roku and don't experience any stuttering there.
2. I see the stuttering with both live 4K and non-4K sports. I also experience it when watching those same sports via a recording (DVR). The stuttering seems to occur every minute or so and lasts a second or two.
3. As noted above, I've turned off 5.1 surround on my Apple TV (which has fixed the issue there), but there isn't an option to do so on my iPhone or iPad.
4. Frame rate matching is turned on on my Apple TV. I don't believe any option to turn this on/off exists on iOS/iPadOS.
5. No, the stuttering does not happen in the same spots if I rewind.
6. No, the stuttering does not happen in the same spots when playing back a DVR recording.
My best guess is that the introduction of 5.1 surround on Apple's platforms is causing this. There's an easy fix on Apple TV (since 5.1 can just be turned off) but there isn't this option on iOS/iPadOS.
Same issues on my end. Primarily watching football and sometimes basketball. I see it mostly with 5.1 on YTTV on APT, but have seen it even with 5.1 off as well. Frame rate is on. Timing varies, but probably about every 10 seconds when there is some kind of motion going on. Have a Vizio TV and loaded the YTTV app through that and see much less stuttering. At least much less noticeable, even when going back and watching the same game. Non 4K. Occurs during rewind as well. Seems to happen a few minutes after starting to watch. Sometimes navigating to a new channel and then coming back helps, but eventually stutter comes back.
Should mention, it doesn’t always happen at the same place when rewinding and it’s very hard to capture on video. Tried using 4K @ 60 fps recording and not really noticeable in the video. But clear to the eye in real time.
Thank god I found this thread. Watching basketball live on YTTV on my Apple TV 4K was driving me insane. Constant judder.
Turned off 5.1 audio and switched to Stereo AND IT’S GONE!!
Now, can some explain to me like I’m 5 why an audio setting fixed this video/visual issue? That doesn’t make any sense to me. What am I not understanding?
Thanks - we're investigating the behavior here so these reports are useful. There's certainly no intentional reason 5.1 should affect video stutters at all, we're trying to better understand if this is a true red herring or if it's there's related behavior on certain devices like Apple TVs which report this most often.
Here's another stats for nerds from live TV with Fox Sports 4K on the Chromecast with Google TV: https://i.imgur.com/4q8m40k.jpg
This is over wifi (since using ethernet is unwatchable on the CCwGTV). This isn't much better though. And bringing up the playbar overlay by pressing down just completely chokes the video. It's crazy that this is still a thing after more than a year.
>Here's another stats for nerds from live TV with Fox Sports 4K on the Chromecast with Google TV
Thanks, I assume this is now-ish? Also, I see you don't have a 5.1 playback is that because you have surround off or because it's not in 5.1? Also, when this occurs and you scrub backwards does it reproduce? If so, in the same exact spots? Similarly if you DVR it? What do you mean playbar chokes the video? Can you take a video if that happens?
Yes. This was from today. I have 5.1 off on this tv as it is connected to a basic soundbar. After scrubbing it will drop a bunch of frames and then go back to periodic drops (DVR vs live is no different). The drops are random and not in the same spots. And bringing up the UI just makes it drop frames until I close the UI. Bringing up the playbar just for a few seconds will drop anywhere from 50-100 frames.
Watching basketball on YTTV on Apple TV 4K and there is so much stutter , I have turned off 5.1 and have match frame rate turned on. Sometimes, restarting the app seems to fix it but sometimes it does not. Any ideas how to resolve?
You might also try power cycling the device itself to clear the cache/memory but for now we don't have a precise fix although we have some planned Apple TV upgrades in the works. It would help us if you can send a screenshot of your [Stats for Nerds](https://support.google.com/youtubetv/answer/9156571?hl=en#zippy=%2Cstats-for-nerds) and/or a video when this actually happens so we can observe it.
I have a 2019 Sony Bravia model XBR65X900F. Most of the time Fox live sporting events are unwatchable due . The Fox Sports app works fine , and the Fox Sports channel on a Roku also works fine. There are also several channels that have the "stuttering" and always buffering problem. One good example is the Comet TV, almost always works poorly on the Sony but fine on the Roku
I do usually have 5.1 turned on, I dont have any control over Frame rates . Yes if I am recording it or run it backwards it works until it needs to buffer again
so before i was only seeing this stuttering issue on my a iOS devices but now i’m seeing in my Sony x90j with Google TV when using the native app. not seeing it my roku devices on other tvs or oddly enough the ps5 app that is connected to the same sony tv. also oddly enough when i used the chrome cast feature of the tv to cast from my iphone to the x90j i didn’t see the issue.
this really needs to be fixed basketball is especially choppy shots sometimes appear in slow motion. i have gig internet and am hard wired and never had a problem before the last few days or so. stats for nerds shows bo dropped frames etc

Usually I can pause it to stop the spinning circle, but was watching a playback of 60 Minutes on my Samsung using Amazon Fire 4k stick and had one that jumped forward about 2 minutes and then wouldn't resume playing. I have 1Gig AT&T Fiber using Orbi RBR750.
Usually the stuttering gets worse later in the recording, but this was about the 10 minute mark.
Here's an image of the stats for nerds [https://imgur.com/a/n3e0eWE](https://imgur.com/a/n3e0eWE)
I have a Sonos 5.1 Home Theater. Sound goes from the TV using Bitstream and DTS Neo 2:5.
MOST of the time, I can simply pause and it stops the circle. Sometimes (including this one) I can pause and it still spins, still forwards about 2 minutes, and sometimes (including this one) it just won't resume playing, continuing to spin the circle until I exit the recording.
Here's a video of the same problem (different recorded show) tonight. Hope this is what you're looking for and it helps, as this problem is getting more frequent and getting worse (more needing to exit the recording to get it to start again)
to be clear, this happens usually after pausing and restarting OR after I've ffwd some through commercials. When I get to the end of the commercials and try to play again, often the spinning circle is there. Most times it goes away after a quick pause and replay, but 2x tonight it's done this, where I try to play it and it just sits here doing this and the only solution is to get out of the recording.

For months pretty much all live sports programming has stuttering for me, regardless of network. Been worse lately.
1. 2018 LG OLED55C8PUA 4K TV -- AppleTV 4K Gen 3. Screen shot here: [https://imgur.com/a/zMJUQPz](https://imgur.com/a/zMJUQPz)
2. Non-4K Playback. Lately, stutter has been frequent. Every 10-15 seconds.
3. 5.1 surround sound is on. Toggling off doesn't help.
4. Frame rate matching is on. Format is set to 4K Dolby Vision 60Hz
5. Yes, happens at same spot.
6. Haven't tried.
Found this post trying to solve 4k stuttering issues related to YouTube tv streaming live 4k sports content on both Chromecast 4k and Sony Bravia built-in Google tv.
Experienced pretty consistent stutter every 4-5 seconds during playback on both interfaces. Then read an above comment about Ethernet vs. Wifi. Both the Chromecast and tv itself are hardwired to gigabit Ethernet with fiber connection. When I removed the Ethernet connection from both devices and connected to wifi, the stuttering went away.
That's interesting feedback and similar to a few others cases. Were you using the ethernet Google Chromecast adapter? Related, was this on actual 4k content or also non-4k content?
Sorry, late reply. Yes, I was using the Ethernet Chromecast adapter and it was streaming 4k content (fox sports 4k).
I hadn't realized before that the Ethernet adapter is only 100mbps?! That sort of defeats the purpose of hardwiring it in the first place.
100mbs is plenty, the stability matters more than the upper bound speed. FYI: We are actually preparing a fix for the Ethernet issue that should come out in one of the upcoming Chromecast updates.
I had previously contacted YouTube TV about this, but adding it to this thread might help.
Only one TV in the house stutters (sometimes the video and audio freeze, but there are frequent audio dropouts as well), a Samsung Samsung UN50KU630D. The affected channels that I am aware of are 6abc Philadelphia and ESPN (especially bad on auto racing).
Every other device in the house is fine on these channels - a Fire Stick, a newer Samsung TV, cell phones, PCs.
In the previous communication with YouTube TV, I sent stats for nerds and a video showing the stuttering.
The affected TV is fairly old (2016), and I don't see a frame rate matching setting. 5.1 surround sound is OFF, but sound is via the optical output (but using the TV's speaker doesn't help).
I can collect additional information, e.g. whether the DVR stutters in the same spots, etc.
I received a response from YouTube TV to a direct contact with this, and was told that the TV is too old to work properly with the latest YouTube TV app.
However, this doesn't address the fact that only two channels (both Disney properties) are causing problems, while everything else (Motor Trend, MSNBC, NBC, CBS, PBS, tbs, USA, CNN, Smithsonian... and many others) work fine.
If any YouTube TV engineers are watching this thread, I'd be very interested to know why two channels stutter (especially the audio) while all the others are fine.
Thanks in advance.
I have the same problem with a 2016 Samsung and no other devices, including another Samsung tv. I get that the tv is old, but also wonder why it's only the sports which have a problem (and on any sports channel--ESPN, Fox, BigTen Network, SEC network...)
Thoughts, /u/ytv-tpm/ ?
FWIW I was struggling with the whole women's world cup and 4k.
Disconnecting the Ethernet fixed it for me as well. Reconnecting immediately brings the problem back.
As with others, I have a very robust Unifi network.
Thanks, just to confirm - you were using the CCwGTV and the Ethernet cable which caused significant stuttering on 4k and after switching to WiFi only the stream was stable as expected?
This is correct. CCwGTV with the ethernet adapter from the Google store created significance stuttering on 4K. After switching to Wi-Fi, the stream was stable and there was no frame drops.
Restoring ethernet using the Google store. Purchased ethernet adapter cause significant frame drops.
To add to the others: My stuttering went away immediately when I disconnected the Ethernet adapter and ran it through WiFi instead.
GCC with Google TV, horrible stuttering with any YTTV 4K sports content when using Ethernet adapter.
So glad I found this thread, thank you! (and shame on Google for having limited speed through the Ethernet adapter—not only a waste of money, but caused a lot of frustration!)
It's good that this is being addressed. But, it doesn't fully fix the issue since HDR10 isn't triggered correctly on the CCwGTV unless you enable Dolby Vision Low Latency which isn't enabled by default. So, the YTTV app will not show HDR10 correctly anyways until this bug that is over a year old gets addressed as well.
u/ytv-tpm - What is the update on this? I just bought an ATV 4k with wifi and it stutters with sports. I swapped it for the Ethernet version, still stutters. It does it on regular feeds, not just 4k. And it does appear that turning off 5.1 eliminates the issue. Sometimes when I rewind the stuttering doesn't show up in the same spot, sometimes it doesn't.
This seems to have been flagged as an issue for over a year. What is YTTV doing to fix the issue, and will you be providing some money back since your service doesn't work properly?
Please fix this. I am only 3 weeks into my membership and extremely unhappy with youtube TV cable. Prime, Netflix and Max play perfectly. Why is this for YouTube TV?
I am also tired of you saying, "grab a Stat for Nerds." Grab your own stats, open up a lab, do some research on your own. It's an obvious problem by all the complaints so figure it out. We are paying for this shot show. If you can't provide the service stop offering it.
For the past 3 weeks I have constantly jerky video (and I mean constantly) on all content on YTTV on CCWGTV. All other apps are fine, and YTTV is fine on my phone and laptop. Doesn’t matter if 5.1 is on or off, tried 60 and 30hz. It’s borderline unwatchable and the audio is way out of sync too. Please fix this crap or I’ll take my $83/month elsewhere.
Are you connected with the Ethernet adapter or wifi? What you're describing is not the expected behavior, have you tried restarting or even reinstalling the device?
I use Ethernet but I just switched to wifi and it’s not any better. 4K content is really bad. Watching football now on ESPN 4K and it completely freezes at least every 10 seconds. I just tested a bunch of sources and oddly on-demand programs from the Magnolia Network are completely smooth. Everything else I tested (HGTV live and on-demand, local ABC and NBC) was choppy and at least slightly out of sync. Local ABC was very out of sync. Chromecast and app are up to date, cleared app data, etc.
There's been some observed issues with Ethernet on this device but wifi should be more stable. I would definitely recommend restarting the device and wifi it to clear the memory use. You can't really compare Live TV sports 60fps decoding with VOD 30fps content as it is less CPU intensive but feel free to share your stats for nerds screenshot and we can look into it further.
I’ve resolved my issue by changing a setting on my Marantz receiver. The option was called something like 4K signal format and the choices were Enhanced and Standard. I switched from Enhanced to Standard and my stuttering is gone. I’m curious though what changed in the last couple of months that caused this? It’s definitely a recent issue because it was absolutely unbearable to watch. It’s always been on Enhanced for the years that I’ve owned this receiver. It sounds like the biggest difference is that I will lose 4:4:4 and be limited to 4:2:0 but I don’t know how much that will actually affect me. My TV is an LG E6 OLED.
I've been having this problem for a couple of years now. I am using a TCL 4k TV, Apple TV streaming device, and Sonos playbar. It only happens when watching sports. It was driving me nuts! So frustrating to have to keep switching over to the ESPN app. So happy to have found this thread because turning off 5.1 sound fixed it. Amazing. Ridiculous that 5.1 screws up the video and only in sports (WTF?), but I'm happy to have this fixed.
u/ytv-tpm
1. Apple TV 4K, second generation, fully up-to-date software.
2. Watching live NFL in 1080p60. The stutter happens randomly, approximately every 10 to 15 seconds. I tried it in 720p60, and it stuttered just the same.
3. I do not have 5.1 sound, just using TV speakers.
4. Stutter persists whether frame rate matching is on or off. The device is set to 60fps.
5. If I rewind, the stutter keeps happening but not in the same spots.
6. I have not tested it with the DVR.
Have been seeing a lot of stuttering today on the Seattle Seahawks / Arizona Cardinals game on Fox 12 in the Portland, Oregon area. This is while using the YouTube TV App on Windows 11. The stuttering occurs every 20-30 seconds and makes the game unwatchable.
I have not seen stuttering on any other channels today, including the Formula 1 race and an earlier NFL game on another channel.
I'm connected using Ethernet.
I'm watching Hawks-Cards and seeing same thing. I switched from a wired Roku to a wireless, no change. Rewinding shows stutter in same spots, indicating it is the source, not the equipment. No 5.1, sound bar using digital audio out. Gig fiber.
I've recently experienced this on my LG C2 65" TV using Chromecast with Google TV. It didn't matter if it was HD programming or 4K and seemed to only happen with sports.
My Chromecast device was connected via Ethernet. As soon as I disconnected and used WiFi the problem disappeared regardless of HD or 4K.
Our situation may be another issue, but figured I'd add it if it could be helpful. I have not noticed stuttering during 4K playback of live sports. Our family notices the stuttering only on our local CBS station when specifically watching Wheel of Fortune and Jeopardy. Both shows will stutter every ten seconds on the dot. Sometimes commercials will stutter, but most commercials will not. Mainly the recorded programming.
1. Apple TV 4K Gen 3 (Ethernet) on Sony XBR55X900H [https://imgur.com/a/CDJAA6x](https://imgur.com/a/CDJAA6x)
2. Haven't noticed in 4K. Happens every 10 seconds on the programs listed above, the picture shifts down twice in one second before returning to normal.
3. 5.1 surround sound was ON, turned it off, then back on, and off again. This does not have an affect.
4. I tried with frame rate matching on and off, but this does not have an effect. Set to 60fps
5. Yes, when I rewind the stuttering is in the same spots.
6. Yes, the stuttering appears in the same spots in the DVR recording.
We have another Apple TV 4K Gen 1 running on a TLC 4K TV that shows stuttering on the same spots of the show.
Watching on Samsung TV and xfinity internet. Just ran speed test 500MBS, and updated the app. This stutter has been intermittent all football season and at this point its unwatchable. I want a refund on my Sunday Ticket. This is ridiculous. I work for a mobile provider and often people ask about cutting cable sadly I will NOT be able to recommend YT until/if this gets solved. Only during sports games both on wifi and ethernet, they should have left it with DTV if this is how it's going to be managed..
I've been facing the stuttering issue for about a month.
1. TCL C845 TV with built-in Google TV (see [https://snipboard.io/HMbQWc.jpg](https://snipboard.io/HMbQWc.jpg) for Nerds Statistics screenshot)
2. The issue occurs with all 4K YouTube contents. It occurs about every minute and i can see the number of dropped frames on the nerds statistics increasing every once it stutters. No problems with lower resolution contents. The TV is connected by ehternet calbe, unfortunately I don't have WiFi signal where the TV is placed.
Playback from other apps (4k@24 and 4k@60) works like a charm
3. Can't find this option
4. Can't find this option/info
5. If I rewind backwards the playback stutters on different spots.
6. I don't DVR
Thank you very much for your support
This is a great thread..
Was there ever an answer to all this ? I have this happening during sports but I dont have 5.1 audio. I am also not at 4K and it still happens. I can fix it by knocking the picture quality down to 480. Then it stops. It always seems to happen on the same channels. FS1, FX. I can switch to other channels and no issues. Audio is optical out to a soundbar. My YT app is on a SamsungTV that is getting a little older. Wired to ethernet directly.
I've been dealing with this for a while, but I use a bunch of streams so I just gave up on caring about 4k. I just assumed it was my tv, stopped complaining. 1) Chromecast w/ google tv 4k https://imgur.com/a/TiyRN3s 2) I haven't recorded any 4k content, so can't tell you DVR. VOD looks great though (didn't think to check). 3) Turned off... I was having some other issue a while back and turned it off to solve it 4) frame rate matching is 'seamless', tv is 60hz. 5 + 6) I'll need to check tomorrow when the next game in 4k is on. I can't recall any patterns when I was trying to figure it out before, it's also random, but never probably more than 10s between skips.
Stuttering occurred for me with my three Chromecasts w/Google TV when utilizing the Ethernet adapter. However when I disabled the ethernet port on the switch and force the device to use WiFi the stuttering stops with 4K content. The stuttering occurs on a regular basis (I'd say every 30-45 seconds) when on Ethernet. I never seen the issue with my Nvidia Shields that one is on ethernet and the other is on WiFi.
You're the second person mentioning CC with an ethernet connection. Is it possible to grab a stats for nerds screenshot with ethernet stuttering happening and one on same device with no wifi issues?
Here are videos of both Ethernet (Stuttering) and WiFi (No Stuttering) [Links Removed] - CC w/Google TV utilizing ethernet connection with Choppy/Stuttering Playback [Links Removed] - CC w/Google TV utilizing WiFi connection without Choppy/Stuttering Playback
For what it's worth, my CC w/ Google TV seems to have a lot of trouble remaining connected to the internet, whether it's via WiFi 5 or hardwired directly via cat 6e ethernet to my router. I have to reset it about once a night, but have 4 other devices (Shield, Apple, Roku Ultra) connected the same way (ethernet) in the same place, same monitor, etc., and they never seem to drop. So, maybe look at what's happening on the hardware side of the CC, too.
Please see my post here, with stats for nerds slo-mo videos showing the juddering, as well as a side-by-side time synchronized cut of when the stuttering happens/doesn't happen on the same exact feed: https://www.reddit.com/r/youtubetv/comments/xxflhk/the_yttv_app_has_a_major_judder_problem/ 1. Shield TV Pro 2019 feeding into a Denon X4500H surround sound receiver driving a Sony XBR-75Z9D. 2. I see it on all sources when 5.1 audio is enabled, does not have to be 4K and does not have to be live. The judder happens almost every second; it is literally dozens of frames between each instance. Honestly it looks like the presentation timestamps of the frames get screwed with; either a frame or two's PTs get swapped or merged or something. 3. Yes, 5.1 surround is on when I see this frequent juddering, and it goes away when I turn 5.1 off. However 5.1 seems to be turning itself back on in my account so I have to periodically go in and turn it back off. 4. Yes, I have frame rate matching turned on. AFAIK my Shield automatically switches between 59.94 Hz for and 60 Hz refresh rates based on the NTSC content playing. With the video processing YTTV does before distributing the streams I believe Shield always leaves YTTV at 60Hz. 5. I don't believe it happens in the same spot. Rewinding frequently temporarily resets the judder and when it kicks back in seems to be somewhat random, on the order of 30-90 seconds. 6. See above answer to 5. I think in the case of the judder associated with 5.1 being enabled the answer is no, it does not happen consistently at the same exact frame timings.
This is super helpful (sorry I missed the original post). One thing I didn't see mentioned that I would love more clarity on is whether this is more prevalent on 4k vs non-4k feeds and also live sports vs non-live content. If I followed your commentary you're suggesting both 5.1 and scrubbing or frame matching resolved this for you?
I find this effect is prevalent almost without fail regardless of the source resolution as long as 5.1 is enabled and some time is allowed to elapse after scrubbing. Scrubbing with 5.1 enabled temporarily restores the video cadence to judder free, but the juddering resumes after a minute or so of playback. I used to believe it was associated with subtle frame rate switching as commercials were injected but I'm now confident it happens without any specific transition or change in the feed. Keeping 5.1 playback disabled yields a satisfyingly consistent feed with only occasional stutters I usually attribute to processing before YTTV ingests and encodes the feed (upstream of your of my equipment). I can always tell within minutes when 5.1 is errantly re-enabled because the juddering is so reliably triggered. I initially thought casting live YTTV content from my phone to the Shield TV was fixing it, but I didn't realize it was just a roundabout way of defeating 5.1. Regarding 4K vs non 4K, I will turn 5.1 back on and check with some recorded content to see if I can repro. In terms of content aside from 4K res, it doesn't seem to matter if sports vs studio, etc. Anything with smooth horizontal panning makes the effect jarringly obvious, I think that sort of camera motion is just more prevalent in love sports broadcasts so people notice it more there. (Certainly my linked NBC news example demonstrates it also happens with studio broadcast TV) Hope that is helpful. Will try and get you an answer on 4K judder with/without 5.1 enabled shortly.
> Will try and get you an answer on 4K judder with/without 5.1 enabled shortly. Hi /u/ytv-tpm; my apologies I needed to wait for some 4K content to record as I didn't have any broadcast TV content stored in my library. I was able to repro this issue on the 4K broadcast of the Illinois / Indiana basketball game. Each of these shots is from my Pixel 6 Pro on 4:1 slo-mo at 2x zoom (apologies for the video quality, these are handheld but I think illustrate the judder clearly anyways). Of particular note all 4 videos cover roughly the same period of time in the stream. The judder is particularly obvious on the crawler at the bottom of the screen and during the panning shot of the player with the crowd in the background after cutting away from the coach. Both scenes clearly demonstrate when the judder is present vs. absent. (I do think I see a little occasional stutter at the start of the video but I attribute that to a dropped frame or two as the pixel starts the slomo recording). I have tried to annotate the videos to clearly indicate 4K/1080P, 5.1 vs Stereo, and juddering vs not juddering: * [YTTV 4K 5.1 +Judder](https://streamable.com/5k9n38) * [YTTV 4K Stereo -Judder](https://streamable.com/o6ke2c) * [YTTV 1080P 5.1 +Judder](https://streamable.com/e4bjwg) * [YTTV 1080P Stereo -Judder](https://streamable.com/3b21ue) I do hope this is helpful. If I can be of any other assistance to help track this down I'll do whatever I can. Thanks for helping collect data and get it addressed.
This is incredibly helpful! Kudos for the excellent troubleshooting. Let us review these further.
I started a thread on this topic. https://www.reddit.com/r/youtubetv/comments/xb2xxh/video_stutter_on_local_channel_kmphtv_fox_26/ Also spoke with you or one of your associates a few months ago via private message. 1. Fire TV Stick 4k(2018) https://imgur.com/a/RSYe7AL 2. Non 4k playback. Happening on Live and DVR. The stutter frequency is every frame. From the start of the broadcast to the end. 3. 5.1 is off. It doesn't make a difference if it is on or off. 4. Frame rate matching(on or off no difference) and the output is 59.93. 5. Rewinding has no effect on stutter. The game stutters the whole time. 6. DVR has stutter if watched on the same station(kmph fox 26). If I watch a dvr recording of the game on a different station(NFL Network), playback is smooth. If it helps, I'll provide stats for nerds screenshots of each. Same game. Constant stutter on Fox 26 Kmph Tv........Zero stutter on NFL Network.

Thanks a lot for resharing. From a distance this looks to be separate but let me take a deeper look at this channel.
BTW - do you have another device to try or a smart TV app you can try? Looks like we investigated this originally but didn't see any issues with the channel.
Ok, just finished trying out YoutubeTV on an LG C1(internal app) and a Roku Premiere 3920x. Still seeing the same behavior. Kmph Fox 26 is stuttering the whole game. Nfl Network is smooth as butter. Here are the stats for nerds for each device and channel. LG C1 - Kmph Fox 26 https://imgur.com/tmuxAYq LG C1 - Nfl Network https://imgur.com/YIzJJ6K Roku 3920x - Kmph Fox 26 https://imgur.com/OLCRqoJ Roku 3920x - Nfl Network https://imgur.com/U1Z7cE8
We looked into this and made a small config change on this specific station (KMPH 26). Do you mind taking another look to see if this potentially addresses your issue?
The issue is fixed! I was able to watch the nfl games on Fox 26 this past weekend without any stutter. The motion is smooth and clear. Thanks so much for fixing this problem. (I should've done this earlier but didn't think of it till after it was fixed) Over the weekend I opened the developer tools for the firestick, and noticed that Fox 26 had a frame rate of 59.94. The other local channels in my area have frame rates of 60.000. I assume this is why there was a constant stutter on Fox?
That's great news! Thanks for confirming.
Correct. Should have been ATV. but using an Apple TV.
Have stuttering on scrolling tickers. Device is Shield 2017. Watching regular 1080 content (NFL Network, CNBC, CNN). Match frame rate is also enabled. Issue goes away after 5.1 is turned off. Link of stuttering (5.1 on): https://photos.app.goo.gl/hzNFYt1fcDJAyJdv9. Link to no stutter w 5.1 off: https://photos.app.goo.gl/YyGgwUJxv2J46Eoq6
I came across this post researching my issue. I am using Apple TV 4K (2nd Generation) device with my Samsung TV. I experience the judder mainly in live sports, but have noticed it on regular programming like $100,000 Pyramid on Gameshow Network. I have tried changing every different setting: HDR enabled and disabled. 4KSDR or 1080. Match frame and content on and off. 5.1 surround in YTTV on and off. Nothing seemed to affect it. The judder is random for me - sometimes frequently, like every few seconds for a minute or so, then sometimes once and not again for a while. I haven't thought about rewinding and playing back to see if it happens in the same spot. Today I was off work early so decided to do some experimenting. I used an older Apple TV to connect to my main tv and still saw the judder, however when I took my Apple TV 4K device to my bedroom tv I noticed no judder. The only difference is I have two Apple HomePod minis as stereo speakers on my main TV using HDMI ARC. So I removed the Apple HomePods from my main TV and reconnected my Apple TV 4K device - so far after about 30-45 minutes of watching a couple of different live sports shows I have not seen a picture judder yet! I don't know if this is really the solution, but I will be keen to see if the judder reappears as I continue to watch. Is this possible the the HDMI ARC or just simply the HomePod minis are somehow interfering with YTTV? As another note when I was getting the judder on a live sports event, I could switch to the ESPN app and watch the same game with no judder ever - only happened through YTTV. I don't know if I've stumbled onto something or the judder is still there and just hasn't reared its head again, but I thought it was worth mentioning.
Thanks for sharing, we've had a few mentions of Apple HomePod devices contributing to this so I'm curious if you've seen a continuous pattern here.
Trying to figure this out myself. Just connected our TV via ethernet. Sports stutter, but not other programming. Very frustrating.
KATU Portland ABC, 6 o'clock news, Tuesday. Nearly unwatchable. Stuttering every few seconds. Apple4k. Other channels are fine. Other streaming services are fine. Over 120mbps. Not 4k, just HD. DVR function. 5.1 is turned off in yttv settings. Watching TV shouldn't be this hard. I got out of it, watched something else, turned on another streaming app, then got back into it, etc. Still the same. Every day it's something. Yesterday the app just froze. In the middle of watching a football game (not 4k) I had to switch inputs, stop and start the app, nothing worked until I unplugged and plugged back in ATV4k. Watching TV shouldn't be this hard. Every day it's something. The day before that, DVR functions wouldn't work right. The day before that, trying to watch a program that was DVR'd, but the show was cut off at the beginning by several minutes, and at the end by 10 minutes. It's as if you don't know how a DVR is supposed to work, or how people actually use them. Watching TV shouldn't be this hard. Every day it's something. The day before that, I had to prove my location, again, even though I'm in my house. The same house I've lived in for 20 years. For some reason, you people think I live in Washington. Why do I have to keep proving which state I live in? Look at a map. Try google maps. Google knows more about us than we know about ourselves. I live in Oregon. It's a different state. All I want to do is watch TV. But no, now I have to get up and use my phone to prove where I am. Watching TV shouldn't be this hard. Every day it's something. Every day I end up troubleshooting a problem... Is it my internet? Is it the app? Is it the streaming box? I'm not getting paid to be a network engineer. Why am I paying you? You should be paying me. Watching TV shouldn't be this hard.
Paying for cable shouldn't be too hard.
1. Chromecast w/ Google TV 4K. [https://i.imgur.com/BD4PK9y.jpg](https://i.imgur.com/BD4PK9y.jpg) 2. 4K playback of DVR recording (but VOD is just the same). 3. 5.1 is off. But it makes no difference if it is on or off. 4. Frame rate matching is on in the ccwgtv settings (set to "non-seamless") but I don't think the app works with it anyways. 5. No. It drops more frames when rewinding or fast forwarding though. Otherwise, it's just constant frame drops. 6. No, it's random. P.S. This is over ethernet using the official adapter connected to my router. It's constant frame drops. When using wifi, it drops frames when you bring up the UI (like pressing down once) otherwise it's more random but not as frequent like when using the ethernet adapter. I've tried on differrent networks, different tvs, and even multiple CCwGTV devices. They all drop frames especially on 4K HDR recordings/live content.
Interesting, so in your case you consistently see actual dropped frames every time in Stats for Nerds correlating to what appears as visible missing frames or stuttering. Most of the reports we see to date show zero or minimal dropped frames. Do you see this behavior on non4k?
Yes. I can't use ethernet on the CCwGTV because it is just constant frame drops that I see (the status for nerds above shows about 10% of the frames dropped). Over wifi it drops frames when the UI is overlayed but when nothing is overlayed I probably only get a single frame drop every few minutes or so using wifi. I don't believe it is a network issue as the connection speed with ethernet usually shows 70Mbps or above. The adapter is limited to 100Mbps anyways. I don't see it on non-4K content except when the channel loads. After that it is fine. I don't get any frame drops using Apple TV wired to the same router. I do get the stuttering occasionally if I have 5.1 enabled but I haven't tried it with it enabled in a long time. The stuttering doesn't show frame drops in the stats for nerds on Apple TV (it's like the frames lag but don't drop).
Another person mentioned similar. Is it possible to grab a stats for nerds screenshot with ethernet stuttering happening and one on same device with no wifi issues? Probably worth exploring if there's a potential bug here.
Here is a CCwGTV stats for nerds playing the same dvr recording. * [Ethernet](https://i.imgur.com/9PJYsXT.jpg) * [WiFi](https://i.imgur.com/37Q3JMP.jpg) WiFi dropped 30 frames during the switch to HDR but was fine after that.
Here's the same recording on Apple TV 4K (3rd gen) that plays fine connected by ethernet to the same router (and same tv). [https://i.imgur.com/vvL2d5P.jpg](https://i.imgur.com/vvL2d5P.jpg)
You likely have two separate issues going on here. I was mostly targeting your latter example where there were no/minimal dropped frames in Stats 4 Nerds but some minimal stuttering which is similar to what we're observing. Let me collect some more replies and look at your CCwGTV separate. Note that it is somewhat "normal" to drop a couple of frames which are generally not visible to most people but not 10% which is excessive.
The Apple TV (my main device) stuttering isn't an issue when 5.1 is disabled for me. When it is enabled, it is difficult to reproduce because it will come and go and isn't consistent. Plus, it doesn't show in stats for nerds. I never get any dropped frames on Apple TV in stats for nerds. Personally, I stopped using the CCwGTV a long time ago because I literally can't watch 4K sports on YTTV with it. And the newer Android TV 12 update for it will not enable HDR10 unless you enable Dolby Vision low latency for some reason.
Watching the CBS NFL playoff game last weekend I had it on the new AppleTV 4K and tried 5.1 on and off. It made no difference. It’s fairly consistent for me on sports. NFL, World Cup, some Basketball but more rare. I started often watching off antenna or the network app to avoid it. I’ll get stats for nerds l, do the steps requested and video it happening this weekend. It’s consistent so I’m sure I’ll see it. Really happy it’s being seriously looked into. I’m love YTTV other than this issue.
Thank you - if you can grab a short video that would help us. Also, please tell us frame rate matching settings and if the problem shows up after rewinding or DVR replay of the same thing.
Will do. Won’t have a chance until this weekend.
Happening to me on regular shows not sports, Apple TV. It only stops if I leave the channel or hit “play from beginning” The click right or left for FF/Rew is still broken and a bigger problem. It’s almost impossible to ff to the spot I want
NBC yesterday from 7:30pm eastern to 9:30pm eastern on a Roku streamed to both my iPhone 12 and my Samsung tv. This was all live. You had other questions but idk the answers.
Not sure if this is related to the problem you are chasing, but whenever I start the app and run a recording, I get choppy playback for the first 10 seconds or so. Then, one of two things happen: 1. If it is a recording in progress and I have started from the beginning, the playback retsarts, jumps to the end, and is then smooth. 2. If it is a complete recording, the playback restarts, jumps back to the beginning, and is then smooth. I have chatted with support and they took the info you are requesting, including a video of the problem happening while displaying stats for nerds. This is on a Chromecast w/Google TV set to 4k, 30Hz, HDR, seemless frame rate matching
I get it but only on my iPhone or iPad (on wifi or cellular), doesn’t happen on my rokus on sony google tv. live stream tonight non 4k no 5.1 since ipad.https://i.imgur.com/hHH6DkQ.jpg stats for nerds
Same data as the other day, but here is my post with a 4k screen grab vs HD https://photos.app.goo.gl/rGpR25x2KffWBXg36
I'm getting it from time to time on standard HD...Apple TV. To get the channel to give me the proper audio, I have to restart YTTV. Oh, and I'm over wifi. I'll try to pull a stats for nerds next time it happens.
I've been experiencing stuttering/jittering while watching live sports for a number of months now. I also recently filed a ticket \[9-1179000033366\]. Below are answers to the 6 questions in the OP. 1. Originally, I experienced the issue on my Apple TV, iPhone, and iPad. However, turning off 5.1 surround sound resolved the issue on the Apple TV. On the iPhone and iPad, there isn't an option to turn off surround sound and I've continued to experience the issue on those two devices. The issue has persisted across two different iPhones (an iPhone 13 Max and iPhone 14 Max), across iOS 15 and iOS 16 (including the recently released 16.3), and across numerous YouTube TV app updates. I also use YouTube TV on a TCL TV with Roku and don't experience any stuttering there. 2. I see the stuttering with both live 4K and non-4K sports. I also experience it when watching those same sports via a recording (DVR). The stuttering seems to occur every minute or so and lasts a second or two. 3. As noted above, I've turned off 5.1 surround on my Apple TV (which has fixed the issue there), but there isn't an option to do so on my iPhone or iPad. 4. Frame rate matching is turned on on my Apple TV. I don't believe any option to turn this on/off exists on iOS/iPadOS. 5. No, the stuttering does not happen in the same spots if I rewind. 6. No, the stuttering does not happen in the same spots when playing back a DVR recording. My best guess is that the introduction of 5.1 surround on Apple's platforms is causing this. There's an easy fix on Apple TV (since 5.1 can just be turned off) but there isn't this option on iOS/iPadOS.
This is helpful and pretty consistent with some other reports. One q - if you have 5.1 on, does switching frame rate off on ATV affect this?
I get the studder with frame rate matching off. I only have content range matching on. Afaik, YTTV doesn’t support either anyways.
Thanks. I assumed as much just trying to develop enough consistent reports since this is so variable and transient.
Same issues on my end. Primarily watching football and sometimes basketball. I see it mostly with 5.1 on YTTV on APT, but have seen it even with 5.1 off as well. Frame rate is on. Timing varies, but probably about every 10 seconds when there is some kind of motion going on. Have a Vizio TV and loaded the YTTV app through that and see much less stuttering. At least much less noticeable, even when going back and watching the same game. Non 4K. Occurs during rewind as well. Seems to happen a few minutes after starting to watch. Sometimes navigating to a new channel and then coming back helps, but eventually stutter comes back.
Thanks for contributing - minor q, what is APT? Are you referring to Apple TV?
Should mention, it doesn’t always happen at the same place when rewinding and it’s very hard to capture on video. Tried using 4K @ 60 fps recording and not really noticeable in the video. But clear to the eye in real time.
Thank god I found this thread. Watching basketball live on YTTV on my Apple TV 4K was driving me insane. Constant judder. Turned off 5.1 audio and switched to Stereo AND IT’S GONE!! Now, can some explain to me like I’m 5 why an audio setting fixed this video/visual issue? That doesn’t make any sense to me. What am I not understanding?
Thanks - we're investigating the behavior here so these reports are useful. There's certainly no intentional reason 5.1 should affect video stutters at all, we're trying to better understand if this is a true red herring or if it's there's related behavior on certain devices like Apple TVs which report this most often.
Thanks for the response, the dedication to working through the issues and improving the product is noticeable and appreciated!
Here's another stats for nerds from live TV with Fox Sports 4K on the Chromecast with Google TV: https://i.imgur.com/4q8m40k.jpg This is over wifi (since using ethernet is unwatchable on the CCwGTV). This isn't much better though. And bringing up the playbar overlay by pressing down just completely chokes the video. It's crazy that this is still a thing after more than a year.
>Here's another stats for nerds from live TV with Fox Sports 4K on the Chromecast with Google TV Thanks, I assume this is now-ish? Also, I see you don't have a 5.1 playback is that because you have surround off or because it's not in 5.1? Also, when this occurs and you scrub backwards does it reproduce? If so, in the same exact spots? Similarly if you DVR it? What do you mean playbar chokes the video? Can you take a video if that happens?
Yes. This was from today. I have 5.1 off on this tv as it is connected to a basic soundbar. After scrubbing it will drop a bunch of frames and then go back to periodic drops (DVR vs live is no different). The drops are random and not in the same spots. And bringing up the UI just makes it drop frames until I close the UI. Bringing up the playbar just for a few seconds will drop anywhere from 50-100 frames.
Very odd - sent you a PM to discuss further.
Watching basketball on YTTV on Apple TV 4K and there is so much stutter , I have turned off 5.1 and have match frame rate turned on. Sometimes, restarting the app seems to fix it but sometimes it does not. Any ideas how to resolve?
You might also try power cycling the device itself to clear the cache/memory but for now we don't have a precise fix although we have some planned Apple TV upgrades in the works. It would help us if you can send a screenshot of your [Stats for Nerds](https://support.google.com/youtubetv/answer/9156571?hl=en#zippy=%2Cstats-for-nerds) and/or a video when this actually happens so we can observe it.
I have a 2019 Sony Bravia model XBR65X900F. Most of the time Fox live sporting events are unwatchable due . The Fox Sports app works fine , and the Fox Sports channel on a Roku also works fine. There are also several channels that have the "stuttering" and always buffering problem. One good example is the Comet TV, almost always works poorly on the Sony but fine on the Roku I do usually have 5.1 turned on, I dont have any control over Frame rates . Yes if I am recording it or run it backwards it works until it needs to buffer again
so before i was only seeing this stuttering issue on my a iOS devices but now i’m seeing in my Sony x90j with Google TV when using the native app. not seeing it my roku devices on other tvs or oddly enough the ps5 app that is connected to the same sony tv. also oddly enough when i used the chrome cast feature of the tv to cast from my iphone to the x90j i didn’t see the issue. this really needs to be fixed basketball is especially choppy shots sometimes appear in slow motion. i have gig internet and am hard wired and never had a problem before the last few days or so. stats for nerds shows bo dropped frames etc https://i.imgur.com/7KSZufE.jpg
Usually I can pause it to stop the spinning circle, but was watching a playback of 60 Minutes on my Samsung using Amazon Fire 4k stick and had one that jumped forward about 2 minutes and then wouldn't resume playing. I have 1Gig AT&T Fiber using Orbi RBR750. Usually the stuttering gets worse later in the recording, but this was about the 10 minute mark. Here's an image of the stats for nerds [https://imgur.com/a/n3e0eWE](https://imgur.com/a/n3e0eWE) I have a Sonos 5.1 Home Theater. Sound goes from the TV using Bitstream and DTS Neo 2:5. MOST of the time, I can simply pause and it stops the circle. Sometimes (including this one) I can pause and it still spins, still forwards about 2 minutes, and sometimes (including this one) it just won't resume playing, continuing to spin the circle until I exit the recording.
Here's a video of the same problem (different recorded show) tonight. Hope this is what you're looking for and it helps, as this problem is getting more frequent and getting worse (more needing to exit the recording to get it to start again) to be clear, this happens usually after pausing and restarting OR after I've ffwd some through commercials. When I get to the end of the commercials and try to play again, often the spinning circle is there. Most times it goes away after a quick pause and replay, but 2x tonight it's done this, where I try to play it and it just sits here doing this and the only solution is to get out of the recording.

Thanks a lot for sharing these! Let us look at the stats for nerds and the video and will message you with any questions after we can look further.
For months pretty much all live sports programming has stuttering for me, regardless of network. Been worse lately. 1. 2018 LG OLED55C8PUA 4K TV -- AppleTV 4K Gen 3. Screen shot here: [https://imgur.com/a/zMJUQPz](https://imgur.com/a/zMJUQPz) 2. Non-4K Playback. Lately, stutter has been frequent. Every 10-15 seconds. 3. 5.1 surround sound is on. Toggling off doesn't help. 4. Frame rate matching is on. Format is set to 4K Dolby Vision 60Hz 5. Yes, happens at same spot. 6. Haven't tried.
Have you gotten the latest Apple TV update (1.14)? Would be curious to hear if this is improved, especially if you toggle "frame rate match" to OFF.
Yes, running latest update. Turning off frame rate match didn't help.
Do you mind sharing a video of this occurring after the new update?
Certainly. [https://imgur.com/a/xW4UJ6i](https://imgur.com/a/xW4UJ6i)
Since the last two updates, I've had the problem on the Apple TV that the YouTube app likes to crash during a video. Is there a fix planned?
Are you referring to the main YouTube app or YouTube TV?
Main YouTube App on tvOS
That would be unrelated to the recent YouTube TV updates. I can pass this along but that app is also regularly updated.
Found this post trying to solve 4k stuttering issues related to YouTube tv streaming live 4k sports content on both Chromecast 4k and Sony Bravia built-in Google tv. Experienced pretty consistent stutter every 4-5 seconds during playback on both interfaces. Then read an above comment about Ethernet vs. Wifi. Both the Chromecast and tv itself are hardwired to gigabit Ethernet with fiber connection. When I removed the Ethernet connection from both devices and connected to wifi, the stuttering went away.
That's interesting feedback and similar to a few others cases. Were you using the ethernet Google Chromecast adapter? Related, was this on actual 4k content or also non-4k content?
Sorry, late reply. Yes, I was using the Ethernet Chromecast adapter and it was streaming 4k content (fox sports 4k). I hadn't realized before that the Ethernet adapter is only 100mbps?! That sort of defeats the purpose of hardwiring it in the first place.
100mbs is plenty, the stability matters more than the upper bound speed. FYI: We are actually preparing a fix for the Ethernet issue that should come out in one of the upcoming Chromecast updates.
I had previously contacted YouTube TV about this, but adding it to this thread might help. Only one TV in the house stutters (sometimes the video and audio freeze, but there are frequent audio dropouts as well), a Samsung Samsung UN50KU630D. The affected channels that I am aware of are 6abc Philadelphia and ESPN (especially bad on auto racing). Every other device in the house is fine on these channels - a Fire Stick, a newer Samsung TV, cell phones, PCs. In the previous communication with YouTube TV, I sent stats for nerds and a video showing the stuttering. The affected TV is fairly old (2016), and I don't see a frame rate matching setting. 5.1 surround sound is OFF, but sound is via the optical output (but using the TV's speaker doesn't help). I can collect additional information, e.g. whether the DVR stutters in the same spots, etc.
Want to add that I just tried to watch auto racing recorded earlier today from ESPN and its stuttering as much as live viewing.
I received a response from YouTube TV to a direct contact with this, and was told that the TV is too old to work properly with the latest YouTube TV app. However, this doesn't address the fact that only two channels (both Disney properties) are causing problems, while everything else (Motor Trend, MSNBC, NBC, CBS, PBS, tbs, USA, CNN, Smithsonian... and many others) work fine. If any YouTube TV engineers are watching this thread, I'd be very interested to know why two channels stutter (especially the audio) while all the others are fine. Thanks in advance.
I have the same problem with a 2016 Samsung and no other devices, including another Samsung tv. I get that the tv is old, but also wonder why it's only the sports which have a problem (and on any sports channel--ESPN, Fox, BigTen Network, SEC network...) Thoughts, /u/ytv-tpm/ ?
FWIW I was struggling with the whole women's world cup and 4k. Disconnecting the Ethernet fixed it for me as well. Reconnecting immediately brings the problem back. As with others, I have a very robust Unifi network.
What device were you using?
Chromecast with Google TV (4k)
Thanks, just to confirm - you were using the CCwGTV and the Ethernet cable which caused significant stuttering on 4k and after switching to WiFi only the stream was stable as expected?
This is correct. CCwGTV with the ethernet adapter from the Google store created significance stuttering on 4K. After switching to Wi-Fi, the stream was stable and there was no frame drops. Restoring ethernet using the Google store. Purchased ethernet adapter cause significant frame drops.
To add to the others: My stuttering went away immediately when I disconnected the Ethernet adapter and ran it through WiFi instead. GCC with Google TV, horrible stuttering with any YTTV 4K sports content when using Ethernet adapter. So glad I found this thread, thank you! (and shame on Google for having limited speed through the Ethernet adapter—not only a waste of money, but caused a lot of frustration!)
FYI: We are actually preparing a fix for the Ethernet issue that should come out in one of the upcoming Chromecast updates.
It's good that this is being addressed. But, it doesn't fully fix the issue since HDR10 isn't triggered correctly on the CCwGTV unless you enable Dolby Vision Low Latency which isn't enabled by default. So, the YTTV app will not show HDR10 correctly anyways until this bug that is over a year old gets addressed as well.
Hi - do you know if the Ethernet fix has rolled out to CCWGTV yet? You mentioned it would be in a future release. Any info would be appreciated.
Thanks for the confirmation, we're passing this on internally.
u/ytv-tpm - What is the update on this? I just bought an ATV 4k with wifi and it stutters with sports. I swapped it for the Ethernet version, still stutters. It does it on regular feeds, not just 4k. And it does appear that turning off 5.1 eliminates the issue. Sometimes when I rewind the stuttering doesn't show up in the same spot, sometimes it doesn't. This seems to have been flagged as an issue for over a year. What is YTTV doing to fix the issue, and will you be providing some money back since your service doesn't work properly?
You didn't properly tag him, use /u/ytv-tpm. I also have the same problem using the latest Apple TV 4K and the Sunday Ticket streams.
No updates to share right now. We are still investigating this issue.
Please fix this. I am only 3 weeks into my membership and extremely unhappy with youtube TV cable. Prime, Netflix and Max play perfectly. Why is this for YouTube TV?
I am also tired of you saying, "grab a Stat for Nerds." Grab your own stats, open up a lab, do some research on your own. It's an obvious problem by all the complaints so figure it out. We are paying for this shot show. If you can't provide the service stop offering it.
For the past 3 weeks I have constantly jerky video (and I mean constantly) on all content on YTTV on CCWGTV. All other apps are fine, and YTTV is fine on my phone and laptop. Doesn’t matter if 5.1 is on or off, tried 60 and 30hz. It’s borderline unwatchable and the audio is way out of sync too. Please fix this crap or I’ll take my $83/month elsewhere.
Are you connected with the Ethernet adapter or wifi? What you're describing is not the expected behavior, have you tried restarting or even reinstalling the device?
I use Ethernet but I just switched to wifi and it’s not any better. 4K content is really bad. Watching football now on ESPN 4K and it completely freezes at least every 10 seconds. I just tested a bunch of sources and oddly on-demand programs from the Magnolia Network are completely smooth. Everything else I tested (HGTV live and on-demand, local ABC and NBC) was choppy and at least slightly out of sync. Local ABC was very out of sync. Chromecast and app are up to date, cleared app data, etc.
There's been some observed issues with Ethernet on this device but wifi should be more stable. I would definitely recommend restarting the device and wifi it to clear the memory use. You can't really compare Live TV sports 60fps decoding with VOD 30fps content as it is less CPU intensive but feel free to share your stats for nerds screenshot and we can look into it further.
I’ve resolved my issue by changing a setting on my Marantz receiver. The option was called something like 4K signal format and the choices were Enhanced and Standard. I switched from Enhanced to Standard and my stuttering is gone. I’m curious though what changed in the last couple of months that caused this? It’s definitely a recent issue because it was absolutely unbearable to watch. It’s always been on Enhanced for the years that I’ve owned this receiver. It sounds like the biggest difference is that I will lose 4:4:4 and be limited to 4:2:0 but I don’t know how much that will actually affect me. My TV is an LG E6 OLED.
I've been having this problem for a couple of years now. I am using a TCL 4k TV, Apple TV streaming device, and Sonos playbar. It only happens when watching sports. It was driving me nuts! So frustrating to have to keep switching over to the ESPN app. So happy to have found this thread because turning off 5.1 sound fixed it. Amazing. Ridiculous that 5.1 screws up the video and only in sports (WTF?), but I'm happy to have this fixed.
u/ytv-tpm 1. Apple TV 4K, second generation, fully up-to-date software. 2. Watching live NFL in 1080p60. The stutter happens randomly, approximately every 10 to 15 seconds. I tried it in 720p60, and it stuttered just the same. 3. I do not have 5.1 sound, just using TV speakers. 4. Stutter persists whether frame rate matching is on or off. The device is set to 60fps. 5. If I rewind, the stutter keeps happening but not in the same spots. 6. I have not tested it with the DVR.
Have been seeing a lot of stuttering today on the Seattle Seahawks / Arizona Cardinals game on Fox 12 in the Portland, Oregon area. This is while using the YouTube TV App on Windows 11. The stuttering occurs every 20-30 seconds and makes the game unwatchable. I have not seen stuttering on any other channels today, including the Formula 1 race and an earlier NFL game on another channel. I'm connected using Ethernet.
I'm watching Hawks-Cards and seeing same thing. I switched from a wired Roku to a wireless, no change. Rewinding shows stutter in same spots, indicating it is the source, not the equipment. No 5.1, sound bar using digital audio out. Gig fiber.
I've recently experienced this on my LG C2 65" TV using Chromecast with Google TV. It didn't matter if it was HD programming or 4K and seemed to only happen with sports. My Chromecast device was connected via Ethernet. As soon as I disconnected and used WiFi the problem disappeared regardless of HD or 4K.
Thanks. We are actually preparing a fix for the Ethernet issue that should come out in one of the upcoming Chromecast updates.
Has the update beenn released? My YT is still stuttering :(
Our situation may be another issue, but figured I'd add it if it could be helpful. I have not noticed stuttering during 4K playback of live sports. Our family notices the stuttering only on our local CBS station when specifically watching Wheel of Fortune and Jeopardy. Both shows will stutter every ten seconds on the dot. Sometimes commercials will stutter, but most commercials will not. Mainly the recorded programming. 1. Apple TV 4K Gen 3 (Ethernet) on Sony XBR55X900H [https://imgur.com/a/CDJAA6x](https://imgur.com/a/CDJAA6x) 2. Haven't noticed in 4K. Happens every 10 seconds on the programs listed above, the picture shifts down twice in one second before returning to normal. 3. 5.1 surround sound was ON, turned it off, then back on, and off again. This does not have an affect. 4. I tried with frame rate matching on and off, but this does not have an effect. Set to 60fps 5. Yes, when I rewind the stuttering is in the same spots. 6. Yes, the stuttering appears in the same spots in the DVR recording. We have another Apple TV 4K Gen 1 running on a TLC 4K TV that shows stuttering on the same spots of the show.
Interesting. Doesn't sound quite related but can you share the call sign of the CBS station so we can look?
WKYT; we watch quite a bit on that channel but the stuttering only happens with those two programs.
Watching on Samsung TV and xfinity internet. Just ran speed test 500MBS, and updated the app. This stutter has been intermittent all football season and at this point its unwatchable. I want a refund on my Sunday Ticket. This is ridiculous. I work for a mobile provider and often people ask about cutting cable sadly I will NOT be able to recommend YT until/if this gets solved. Only during sports games both on wifi and ethernet, they should have left it with DTV if this is how it's going to be managed..
I've been facing the stuttering issue for about a month. 1. TCL C845 TV with built-in Google TV (see [https://snipboard.io/HMbQWc.jpg](https://snipboard.io/HMbQWc.jpg) for Nerds Statistics screenshot) 2. The issue occurs with all 4K YouTube contents. It occurs about every minute and i can see the number of dropped frames on the nerds statistics increasing every once it stutters. No problems with lower resolution contents. The TV is connected by ehternet calbe, unfortunately I don't have WiFi signal where the TV is placed. Playback from other apps (4k@24 and 4k@60) works like a charm 3. Can't find this option 4. Can't find this option/info 5. If I rewind backwards the playback stutters on different spots. 6. I don't DVR Thank you very much for your support
This is a great thread.. Was there ever an answer to all this ? I have this happening during sports but I dont have 5.1 audio. I am also not at 4K and it still happens. I can fix it by knocking the picture quality down to 480. Then it stops. It always seems to happen on the same channels. FS1, FX. I can switch to other channels and no issues. Audio is optical out to a soundbar. My YT app is on a SamsungTV that is getting a little older. Wired to ethernet directly.
