I have seen problems occasionally with FFMPEG and I use it to transcode video a alot
I have seen problems with HEVC so I am wondering if there is an updated version available yet
maybe handbrake is more capable?
Handbrake is good one, but it's not so powerful as FFMPEG. I need batch transcoding, multiple filters, etc. If I encode the same video using libx265 - it works perfect but slow. The issue is definitely not in HEVC itself, but in using/tuning FFMPEG AMF parameters.
Handbrake has batch capability so its not so bad for smaller jobs
could you provide the following information?
1) FFmpeg version
2) could you share stream you are trying to encode?
3) FFmpeg output after encoding like:
