Is it safe to use the yuva420 pix_format option with ffmpeg to encode webm videos?
it was something like this accross old and new ffmpeg versions:
ffmpeg -framerate 30 -f image2 -i frames/%04d.png -i my_audio.flac -c:v libvpx-vp9 -b:v 0 -tile-columns 2 -crf 18 -c:a libopus -b:a 128k … It reports:
vp9 (Profile 0), yuv420p(tv, progressive) and alpha_mode: 1
Interestingly, the output webm file size using yuva420p is smaller than if I omit the pix_format option. …
