Description
Hi,
There's high compression artifacts using the codec "prores_ks" with an Alpha channel (4444 mode)
example:
ffmpeg -i intranspfile.mov -c:v prores_ks -profile:v 4 -pix_fmt yuva444p10le -profile 4444 -metadata:s encoder="Apple ProRes 4444" -vendor apl0 -acodec pcm_s16le -f mov outfile.mov

As you can see in the linked files the Alpha Channel is producing compression bug in the color but not in the alpha !!
