Although the attached render file AVC_Intra_100.mp4 was checked in awhile ago, I have NOT been able to get AVC_Intra_100.mov to work on Fedora 32. Error I get is:
> [libx264 @ 0x7f9b9c0b1040] 8-bit AVC-Intra is not widely compatible > [libx264 @ 0x7f9b9c0b1040] 10-bit x264 is required to encode AVC-Intra > FFMPEG::open_encoder err: Generic error in an external library > int FFMPEG::open_encoder(const char*, const char*): > open failed libx264:/tmp/hdrnmm.mov > If I delete the input line of "avcintra-class=100" which is perfectly legal per "view" it works, but then there is no point!
