4K HEVC - slow frame rate

Plex server- latest (windows 10 server)
Infuse - Apple TV 4K, all up to date

I have noticed some slowdowns, the frame rate will lag. When watching 4k content. This has been happening for a while, not only on 4K but various types of media.

It will usually happen at the same scenes every time, I have tried turning on Match Content but it did not help.

I know you said “up to date” but could you provide the version numbers for Infuse and the tvOS? Also have you done a speed test from within the Infuse app for this video?

tvos 14.2
Infuse pro 6.5.4

Here are my speed test results

Do you have both Match Frame Rate and Dynamic Range turned on in the ATV settings?

Your speeds sure look good enough that you wouldn’t be seeing a speed lag.

Also, some TVs have a smoothing setting that will cause what you’re saying too so that may be part of the problem.

It happens on multiple TVs so I don’t think the issue is the tv. I have tried match content on and off but it hasn’t helped my main tv is 4K but not hdr

Guess there isn’t going to be anything from the devs about this issue?
