  • How to convert a 4K ProRes into different formats with FFmpeg ?

    18 octobre 2018, par adsalpha

    I have a video which is 3840 × 2160 encoded using Apple ProRes 422.

    I need to convert it to the following sizes/codecs without losing in quality :

    1. ProRes 422 1080p ;
    2. H264 4K ;
    3. H264 1080p.

    I need to do it programmatically so I went with FFmpeg. My command is ffmpeg -i input.mov -vf scale=1920:1080 -c:v prores_ks -preset slow output.mov. I don’t like the result – the colors are less saturated.

    What is the right command to do it ?
