Thanks for this. Did you double-check that it's true HDR, with all the HDR metadata present, and not a similarly-looking conversion? I'll try to find time to run some tests of my own tomorrow. Very excited to see HDR working again.
EDIT: tried running a couple of quick tests on the file I linked earlier before going to bed, no luck achieving the correct results with this. The closest one still looked like a conversion. Didn't have time to check metadata or even MediaInfo. Will try again tomorrow. In the meantime, could I please bother you with giving this particular video a test run and confirming that the encoded result has HDR and works on your end? What settings need to be changed on a clean new file import, apart from setting Color Space Rec 2020 on the Export tab and "colorprim=bt2020:transfer=arib-std-b67:colormatrix=bt2020nc" in the encoder?
Yes it's proper HDR, no conversion, and proper metadata.
As for your source file, I had to do a remux as premiere wouldn't even accept it as is. Looks like it was a renamed MKV file. After remuxing, I imported it and you need to make sure the clip and sequence are set like this:
Then in export set it up like this:
In the video encoder node you'll want to add your HDR metadata: (these are the values from your source clip)
I think I did find a bug though. If you set up the exporter with 4:2:0 like this:
It won't work. Only 4:2:2 worked for me. I used that since my footage is already 4:2:2 anyway, but I didn't realize the 4:2:0 option wasn't working correctly until just now.
Also, you shouldn't need this now:
Zitat"colorprim=bt2020:transfer=arib-std-b67:colormatrix=bt2020nc" in the encoder
