I’m getting back material from a color house for HDR. I’m doing the conform.
Color House is doing Rec2100 HLG.
Client needs Rec2020 HLG.
How do I flag the output to be correct?
Who’s the client? Rec2100 HLG should be correct for a HDR delivery.
Just checked, NBC. Rec2020 only.
I think you just need to put a colour management node on top of the timeline and do a view transform from 2100 to 2020. But that’s a guess.
EDIT Ignore me. I don’t even see a rec 2020 in the list
What’s the difference? I always thought 2100 is the HDR version, so that would be HLG, and 2020 is the SDR version.
2020 can also be HDR
Exactly, No Rec2020 in the list
Actually, you can set it up as Legacy 2020 to 2100HLG, then invert.
Whether this is correct or not, is a guess.
Can you share the spec?
Format: 1080p/50
Color space: HLG Rec.2020
Codec: DNxHR HQX
I am 100% not a reliable authority, but I’d bet money that spec is wrong and nobody up or down the chain knows.
I’ve spent enough time trying to get answers about various specs that I believe very few people know what they’re asking for and will give you dead eyed stares that make you think the next sentence out of their mouth will be, “…but Brawndo’s got what plants crave…”
I think rec2020 HLG is rec2100 HLG.

Rec2020HLG and Rec2100HLG are the same thing. So they can be tagged either way and be technically correct.
Rec2020 and Rec2100 have the exact same gamut. Rec2100 just adds the HDR EOTF/Gamma stipulation that it must be PQ (aka St2084) or HLG. Since you are specifying the HLG gamma curve, they are the same thing.
Flame only has the option to tag as Rec2100HLG. They can’t reject you for that tag as it is technically correct.
