[HELP] Setting PAR and color matrix on container-level

[potejan]

PAR and VUI signaling should be on stream not container level.

MKV allows additional HDR related signaling through the container.

I'll be honest, I'm clueless where the signaling is or should be stored. With my mkvmerge options above, it gets picked up in both players and ffmpeg. Does that go in container or stream? I actually tried the "MKV tagging" tab in Hybrid, which I think definitely goes in the container, and setting the color properties there got utterly ignored by virtually every player and tool I tried, including ffmpeg.

without any clue how ISO/IEC 23001-8 I would need some additional details on how to use nclx and nclc

I wish I could help with this one, but looking at the docs it means even less to me...

For my use case the mkvmerge options are more than enough though, so no pressure if this is a complicated ask!

Good luck with moving!

Thank you
