[FFmpeg-user] White Padding Looks Gray

[Morgan Bellinger]

Brilliant! Your second solution works. I had previously tried yuv420p
without success. Here's my new working command line:

ffmpeg -i p.MOV -vf
"format=yuv420p,transpose=2,pad=1920:1920:420:color=white,format=yuvj420p"
c.MOV

Thanks so much for your help.
