CIExy scope not showing HLG

[cicero]

Thanks Adam. I’d never heard of P3D65-HLG so there you go.

As mentioned in another recent conversation, we are working at P3D65PQ but want to view at Rec2020 (=2100) HLG, before we then burn that same View Transform into the eventual deliverable export.

Managing Multiple Grades

Sorry, didn’t explain properly. Not looking to compare side-by-side or anything like that. Totally agree with all your points about the pitfalls and futility of that! Our primary del is the HLG, so that’s what we (only) want to be looking at with the client while we do the work. But we want to be actually working in PQ until export, because the PQ > HLG conversion is more solid than HLG > PQ (so don’t want to bake it to HLG at grade export or Flame import), and obviously for the secondary PQ d…

So the pipeline is working but I want to see that HLG on the CIExy scope, to check that it is Rec2020 primaries but constrained within the P3 gamut.

I think our exact colour pipeline is actually a red herring here, it just seems Flame won’t display whatever-gamut, with HLG gamma, on a CIExy scope.

Thanks for mentioning the BBC LUT. We collaborate with BBC R&D a fair bit, so yes that’s the one we’re using for the View Transform. We also found the same as you, that it matches a standard transform anyway
