I am using this code:
ffmpeg -i in.mov -c:v hevc_videotoolbox -allow_sw 1 -alpha_quality 0.9 -tag:v hvc1 -q:v 100 -vf premultiply=inplace=1 out-n.mp4
To convert my MOV with alpha to MP4 with alpha for a web use. However the export color is different.
Original:
MP4 Export:
Any idea of how can I keep the original MOV colors?
Thank you
