It's a bit outdated but still good for background info.
Does anyone have any hints on saving the alpha channel? I have tried
encoding an exr with alpha channel into a mov file with the following
command:
$ ffmpeg -i bunny.%04d.exr -c:v prores_ks -profile:v 4444 -pix_fmt
yuva444p10le bunny.mov
and I get a mov file but without an alpha channel. ffprobe reports:
Stream #0:0(eng): Video: prores (ap4h / 0x68347061),
yuva444p10le(progressive), 1280x720, 61876 kb/s, SAR 1:1 DAR 16:9, 25
fps, 25 tbr, 12800 tbn, 12800 tbc (default)
