[HELP] x265 thumbnail problem

[ssdde]

I think I found where the problem is. Seems like PotPlayer and the thumbnail generation only knows of 'hvc1' and not 'hev1' as stream tags for MPEG-4 HEVC.
Enable "Config->Output->Container Settings->Mp4 Settings->Force HEVC tag" and set it to "hvc1" and your files should work. (you can remux old files to fix this, no reencode necessary)

really, you mean setting like this?




and how to remux old files without reencode?
