Thanks for creating this issue. Can you tell me which specific tags you look for when trying to get "4k hdr"? These quality labels aren't totally clear to me. Do you think "RAW HD" is synonymous with "4k HDR"?

I think my confusion is that "HDR" is not a quality per se. 720p, 1020p, etc are qualities. nefarious groups qualities and sources (i.e bluray, webrip) into quality "profiles". I'm trying to wrap my head around how to best integrate "HDR". If you have any ideas, please send them along.

As far as I can see it's usually in the name. HDR is not really a quality profile because any resolution can also have HDR. I think it's more of an additional setting on top of quality.

That would be awesome =)

Alright, I'm sold on the idea. I'll keep this issue open until I have some time to tackle it, but my current idea is to keep the existing profiles but then include checkboxes for "modifiers". The radarr projects uses these but I don't really understand all of them and will at least include "HDR":

• REGIONAL
• SCREENER
• RAWHD
• BRDISK
• REMUX

This Wiki explains them pretty well: https://en.wikipedia.org/wiki/Pirated_movie_release_types

Thanks @Clickbaitcake, that's definitely helpful. I plan on downloading sonarr at some point to mirror some of it's quality profile logic when I'm ready to tackle this.

I think HDR is a value of a color-space property, in the same way that 1080 is a value of a vertical-resolution property.

So 1080p should inform the vertical-resolution and refresh-rate properties, and HDR should inform the colour-space property.

Then there is the bit-rate property, the remuxed property, the source (cam, hdr, etc.), and subtitle-language and audio-language properties.

None of these alone tell you the overall quality, but that could be calculated by combining the different properties.
