I have a 10 bits .mov file with YUV color space encoded prores 422HQ of some green screen footage. -Do we always need to convert videos with a YUV color space for compositing work?

If I want to convert the footage via ffmpeg to images,I am not sure to which color space and how to convert in a right way videos with chroma subsampling of 422?

    Blender can use YUV video. Almost all compressed video is YUV, there are only one or two RGB codecs, so it makes sense.

  • @stib thank you for your answer. Regarding videos with more than 8 bits- I read that blender has a problem interpreting in a right way videos with more than 8 bits (Some places in blender, for example, the video editor will interpret 10 bit videos as 8 bit. That's why I want to convert the video to image sequences via FFMPEG. I don't know what is the right command and what is the proper image format that will maintain the highest quality as well as the proper color space and how to convert in a right way videos with chroma subsampling of 422?
