Stutter during tv show playback

Help and Support
1

Hi
I have audio and video stutters during playback of tv shows if the file I try to playback is in 1080. The strange thing is that movies work fine in 1080. Only with tv shows I encounter this issue.
I use a Raspberry Pi3 (Model B) with OSMC installed (I also had the same issue with Openelec). I tried to play the files from my NAS (connected with NFS) or to playback from an USB drive. Both with the same result. Here are the maediainfo data from one of the files with the issue:

Any idea how I can fix this?

HEVC (aka H.265) is not hardware accelerated on Pi.
We have some GPU acceleration, but 1920x1080 probably won’t work well.
With overclock on Pi3 you can play some videos, but it depends on the encoder options.
720p will largely work okay.

But, probably best to stick with H.264. You can convert this video to H.264 with tools like handbrake or ffmpeg.

That resolved the issue. I converted the video and then it works fine. Thx for your help.

Also a 10bit color cannot be played with hw acceleration.
