    Resolution Note (fix version 2022.1):

    Fixed in 2022.2.0a1

    Every file had an unknown color standard. To remove the warning, you should check how to add the color standard in the file while editing or recording. You can use FFmpeg to add it, but you have to reencode your file, lowering the quality. Use and customize this command for your need.

    ffmpeg -i input.mp4 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range pc -vcodec libx264 output.mp4

    We reduced redundant warnings, so you should see only one per file.

    I am getting exactly this issue, no idea how to fix it. the video i am using is an mp4 exported from after effects. Idk what you mean with "color standard" of a video as i never heard of it and google doesn't seem to give any results. could you please specify what you mean by "you should check how to add the color standard in the file while editing or recording"? Thx
