While we wait for Dave I just grabbed your sample.
It is choppy, however it’s also choppy in VLC player and Infuse. I can’t speak about Emby as I no longer have it installed. However I do seem to recall that Emby had some feature that helped with playback for files it considered badly encoded.
As for the darkness I don’t see that at all.
As a side question are your files personal self rips?
No need to discuss here exactly where they are from if the AREN’T self ripped. I will just assume.
i created the sample using the method they described in his post. not sure if its the same
Ugh. i totally should have checked this before uploading. i followed the method on the plex page to create the sample. it is all messed up and choppy. the OG file is not. something is wrong with how i created the sample.
i followed this: Generating Sample Files from Media | Plex Support
Hmmm, if that’s the case, I’ll need a different sample then

I had the same issue with an HDR movie. Two things worked:
None are permanent solutions but in a pinch, it allows me to watch the content.

how can i make a sample of an MKV that isnt choppy? any tips?
ok i figured out my issue. my issue was that my sony TV HDMI input setting was on normal instead of enhanced. switching that allowed my apple tv 4k to switch to dolby vision mode and now everything looks amazing. had already done so on the sony receiver, didnt realize i had to do it on the tv too.
dunno if this will help anyone else… but figured id post it
Same here 
thanks for possible solutions, but there has to be a software fix…
why there is no dev response?
There is a response and it asked for a sample file of a video with issues, which as yet has not been supplied.
There can be no software fix until the cause is found.
It’s easy to track the issues down if it’s a global thing happening to everyone.
In this case it clearly isn’t.
EDIT.
Even the post above yours states that this issue was caused by a setting on his TV and nothing to do with Plex.
Others have said that the issue only happens in Plex and Infuse works fine.
So probably not even the same issue.
But again everyone just hopes that someone else will take the requested steps to help troubleshoot.
Well, I can’t provide a sample, but: playing back via the iOS app does not show the error. Neither does playing back via web player.
So, yeah, maybe it’s something which is connected to TVs, but I don’t have a Sony TV, but a Philips (OLED 65 Inch, capable of HDR and 4k), so maybe it’s software connected after all as it occurs with at least two different TV manufacturers.
I’m not saying it’s not software.
I’m saying there can be no software fix until that’s confirmed.
But that can’t be confirmed until someone can be bothered to provide the info that’s asked for.
Alright. I see whether I can find a sample which shows the error and then I will post it here.
Thanks!
people have tried to “provide what is asked for” and i have offered to upload a file known to not work. but no one ever responds but to say remarks like someone should provide logs and stuff.
If i ran Plex I would have hardware for each device we released our software for including the NEW AppleTV for testing and this could have been fixed long ago.
Right, I’m done here. I always try to help here when I can and every now and again I think why even bother. God only knows how the unpaid Ninja’s feel.
Taking that a step further, you expect Plex to have every model of ATV, linked up to every model of TV connected to every model of soundbar/AV Receiver.
I’m on the new Apple TV. I have no issues and am purely trying to help you guys out. Despite having no issues I prompted this to come to the attention of @DaveBinM
I really do not care if you have offered to upload a sample file in “another thread.” You haven’t in this one.
This is the thread that it’s been asked for and the one that thanks to me now has some Plex attention.
You personally have wrongly stated that logs cannot be provided for the ATV yet two users have provided them. (AKA some can’t be bothered and easily identified by their lack of helpful/factual input)
To be honest, I found a solution that worked for me: switched to 4K SDR within Appke TV settings, started playback, switched back to 4K HDR and resumed playback. For whatever reason that solved the issue…
And that is valid input.
As bizarre as it sounds it will probably help Plex debug the issue that some people see.
I thank you for trying to help! but yes i did offer to upload and if you look I started this thread and have been following close. also i reached out to “Plex Employees” with no reply. as for having each AppleTV… yes 99% of problems are related to the streaming device NOT the TV. so I would have AppleTV, Roku and so on. but that’s me.
and as for the AppleTV “LOGs” I still haven’t seen logs from an AppleTV but from plex server. and its clear that PMS is NOT the issue here. so if you know how to connect to a proprietary device like and AppleTV and get logs of of it then please tell me step by step so myself and others that are having this issue can provide them.
Im not mad or lashing out even if you think i am, i am however frustrated with the fact that i reported this issue 2 months ago and AppleTV has has many updates sense then but nothing to fix this issue.
thanks for your support!!
Switching to SDR seems to have resolved my issue somehow so thinking it’s the auto detection of HDR capabilities?
Nor me.
However, @Orko linked how to get logs around post 21/22
If that doesn’t work for you then that’s a completely different issue, but again the fact that those two users did provide logs means it IS possible.
If you have links to other posts specifically for this issue I will be more than happy to read up.
If I can correlate anything from other threads that are relevant o this I will happily pass that on.
Failing that this is is a 58 post thread ONLY involving around 7 or 8 users. One of which is me and one of which discovered the issue was NOTHING to do with Plex.
it’s hardly enough to suggest there is some mainstream issue that Plex should have an instant fix for.
Don’t get me wrong. I have a long history of hitting on plex failings over the last 7 or 8 years.
TL;DR @DaveBinM will still need someone to provide that sample file.
Also I apologise if I’m coming across as snarky.
