1750,Prores encoders do not support writing alpha,cehoyos,,"Kostya's prores encoder currently only supports PIX_FMT_YUV444P10 as yuv444 format, meaning no alpha channel is written to the output file. See ticket #1728 for a sample with actual alpha content.

There is currently no suitable pixel format in FFmpeg, see ticket #1749 for the enhancement request.",enhancement,new,wish,avcodec,git-master,,prores alpha,,,,0,0
