  1. 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.

    AZAIKANG's solution of changing the Mp4 Codec from H264 to VP8 worked for me!

    My friend AZAIKANG is right. I am using 20201.3.20f1 and changing the codec to VP8 fixed the warning and the actual rendering issue.

    We are having this issue in Unity 2021.3.9f1, but the problem seems to come from Unity itself and not the .mp4 file.

    Our video has correct color standard:

    But when we check `Transcode` in the import settings, this warning is printed again.

    When we uncheck `Transcode`, the warning is gone but another warning show up about we're not transcoding our video.

    I've found a solution using a .mp4 H264 Video File.

    1. Open Unity, click the Video Clip and open its Import Settings.
    2. While in the Import Settings, you go change its Codec format from Auto into VP8.
    3. The "WindowsVideoMedia error unhandled Color Standard: 0 falling back to default this may result in rendering issues" warning is gone after that. Hope it works for everyone.

    Ignore my last comment: Re-encoding it the way mentioned in the resolution note does not fix the problem for Unity 2021.3.6f1.
