You cannot specify yuv420p as pixel format as it is not supported as output format. You need to set vvenc-params: -vvenc-params internalbitdepth=8 For instance: ffmpeg -i input -c:v vvc -b:v 2M -vvenc-params internalbitdepth=8 output

@lehmann-c set -vvenc-params internalbitdepth=8 works, thank you!
