Comments.Text: @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?

Comments.Text: @stib I tried to output the video with h.264 codec lossless, with avi or mp4 container and the result is 8 bits video.(pixel format of input video is yuv422p10le).
  I came across a similar  [question](https://blender.stackexchange.com/questions/73743/lossless-10-bit-colorspace-yuvj420p-video-output) and the workflow described in the comment before the last- where it is suggested
  to convert the video to a 16 bit TIFF images, so that's what I'm trying to achieve now, but I don't know the proper command
  to convert in the right way a YUV video with subsampling of 422 to image sequence?

Comments.Text: Well I tried using ffv1-still 8 bits. There is no option for prores codec in blender as far as I know. I don't think I can output this video with more then 8 bits though. I would just like to learn how to convert the video to image sequence using ffmpeg and maintain the same quality?
