Bad quality encodes to Prores4444 with alpha from ffmpeg

Can't tell if prores4444XQ is any different than prores4444 in ffmpeg 4.1
FFmpeg does have 12 bit pixel formats but the prores_ks encoder is limited to 10 bits. The 4444XQ profile features higher bitrates. Open a ticket at trac.ffmpeg,org, if you like.
