First of all, thank you a lot for this great plugin.
Now, to my question. I'm trying to create some H.265 files to use in calibrating my projector. Ideally, I'm trying to produce SDR and HDR versions of the file in 4:2:2 and 4:2:0 chroma subsampling.
The only color spaces available are BT.601 and 709. I'm no expert on this, but, I presume it should be possible to do 709 HDR, but in most discussions I've seen on detecting HDR people are checking BT.2020, that it's at least 10 bit, and the transfer function of something like PQ or HLG, and to select HDR in the normal HEVC exporter, you first have to select BT.2020.
So, is HDR a feature you've not implemented yet?
