Off the top of my head, I have had similar glitches with Bridge on the River Kwai and Zero Dark Thirty but only in a few scenes and not nearly as extreme as this example. Here’s the MediaInfo for this Star Wars movie for what its worth:

Anything look odd? The file plays perfectly fine on my computer, even over WiFi.
Tomorrow I’m going to put the movie into an M4V and MOV container. Maybe it will play nicer with Apple’s software.
My 2cents… under AppleTVs own config → video and audio → match content (Matcha innehåll)… change from Off to ON… it may flicker between 50/24 every time you start an app or video depending on TV etc but after I changed it to ON I could watch Black Panther 4K (hevc) (streaming from my QNAP NAS) onto 1920x1080 (FHD…not 4K) Samsung TV and Apple TV 4 (not Apple TV 4K) without stuttering. If Match Content is off, it started to stutter on that 4K movie… (and as I doesn’t have a 4K screen there is no obvious reason to download 4K for me… this was just one of the simpler tests I did with diff 4K sample videos with Infuse and my Apple TV 4).
But I know there are many other 4K videos that aint able to pull it thru due higher bitrate etc… for that Apple TV 4 K would be needed as A10 can chump hevc directly…
My other 2cent… If it is a ”pirated copy” of a movie that seems to have a problem I would suggest the possibility of a copyprotection scheme used… the movie “John Wick” have a “funny” copy protection scheme that results in a copy were the chapters are changed! Why not the possibility of a copy protection scheme that jerks with the frame rate or otherwise?
The Star Wars movie is a fan-made film scan that is distributed exclusively through torrenting for now. In the case of the other movies, the glitching is far less noticeable in Infuse and doesn’t appear at all during playback on other devices.
Thanks! This was the first video where I’ve seen this “glitch” this severe. Hopefully it’s nothing too difficult to find the cause.
Wow, that’s janky. Does it only happen at that particular point in the movie? Or does it happen randomly in many different places?
Just as a control, I’ve put it on a SanDisk USB 3.0 stick and plugged it directly into my 2016 LG OLED6EP and it plays perfectly - so far. (I stopped it at the Canteen scene, so I didn’t get as far as your stutter glitch point - but I had zero problems up until the point where I stopped playback.)
P.S. I’m keenly interested in this issue as I have an TV 4K coming in a few days and the first thing I’m going to do is buy Infuse 5 Pro for it. Would rather play 4K77 off of my Mac mini’s RAID via Infuse on the TV 4K than have to stick a USB stick in the TV all the time.
The only way I’ve been able to watch it so far is with a long cord to my i7 win 10 desktop, but then DTS doesn’t work so I end up on the non-DTS '83 remix audio, and to be fair the whole reason I got the ATV4K and Infuse was to stop doing nonsense like that!
I got an Apple TV 4K over the weekend, and immediately purchased Infuse 5 Pro and installed it.
My initial reaction is mainly favorable (it played most of my test files I threw at it) but when it came to 4K77, it failed miserably.
I got the janky stuttering pretty much from the get-go - opening scroll.
Of course, the problem now is that there’s no way to know if it’s an Infuse problem, an Apple TV 4K the-hardware-isn’t-good-enough problem or a playing-an-80-Mbps-file-over-Gigabit-Ethernet-off-of-a-Mac-mini-Thunderbolt-attached-RAID-box problem. Or (d) all of the above. :-/
I’ve had the file playback well now in a few places - MPV on Linux, Windows 10’s built-in Movies, and now off a USB to an LG 4k OLED. Its funny the LG specs say it only does 50Mbps HEVC max but it had no problems at all playing it.
I tried re-muxing it with latest MKV tools and reduced the audio tracks to just the 3 main english DTS ones (stereo, 5.1, mono) but that didn’t help with Infuse on ATV4K playback. I tried hardwiring to my main 1Gbps switch too but also no joy.
MPV doesn’t show any real errors - just one or two during the crawl but otherwise it seems pretty happy with the file.
It’s weird. It plays perfectly fine on my computer even from my NAS over WiFi. But if I copy the video to my iPhone and try to play it in the Apple Photos app or the VLC app, I get the same stuttery playback I get on my Apple TV.
Exact same problem here, identical to your example video. It happens only on hevc encodes for me (I use staxrip via Intel h/w encoder). These hevc files play perfectly fine on roku, xbox one, ps4 pro, pc (vlc) w/ no issue, but stutters on my apple tv 4k and ios in Infuse or native plex app. Identical to your example! I have over a hundred of these files it does it on (hevc encodes).
Can Infuse please at least add an option to force transcoding at the individual file level like the native client please? Until then it’s totally worthless to me. Either that or fix this issue that no other system has.
I’m so close to giving up on Apple and going to a roku for all my clients.
