ffmpeg ProRes Encoding commandline
We use the -c:v prores_ks codec, which is best compatible to the original ProRes codec.
ffmpeg.exe -i inmovie.mov -c:v prores_ks -profile:v 3 -pix_fmt yuv422p10le -c:a pcm_s16le -b:a 48000 ProResMovie.mov
Sometimes audio mapping is necessary to bring in all audio channel from the source file.
The example below maps 4 mono channels to the ProRes movie:
ffmpeg.exe -i inmovie.mov -c:v prores_ks -profile:v 3 -pix_fmt yuv422p10le -c:a pcm_s16le -filter_complex “[0:a][0:a][0:a][0:a]amerge=inputs=4[aout]” -map 0 -map “[aout]” -b:a 48000 ProResMovie.mov
The ProRes profile can be defined with the paramaters below:
ProRes Parameters
