Adding Colorimetry Flags in mkvtoolnix

Question

I have some .m2ts videos I’m remuxing to .mkv using mkvtoolnix, and I want to add colorimetry flags for the output files. How do I do that in mkvtoolnix?

Answer 1

I found the solution. I just needed to put a number in "Color matrix coefficient", "Transfer characteristics", and "Color primaries" and my video now had colorimetry flags.
