Version 16: Text caption colours with HLG/REC2020

PostFri Apr 12, 2019 6:21 pm

I am shooting HLG on a Sony Z90 with profile 10 (HLG2/REC2020).
In the Preferences/Colour section you can see (attachment) I use the output profile (REC709) and everything else is REC2020/HLG.
My question is this:
If I insert text for a title, on a track, the colour doesn't match what I choose in the 'colour picker' for the text.
How do I get the text colour I want on the track?

The video it's self is really nice with no grading at all (as expected). The only correction I do is 'gain' if I miss the exposure slightly.
Up until now I have used SLOG2/Pro/REC709 for my shooting on both Z90 and FS5.

Thanks for this thread. This probably would have bitten me in the future as I move more onto Resolve. I plan to work towards an HLG workflow myself now that there's better information on the web. (including here :mrgreen: )

When you're using Resolve Color Management, the "input color space" field tells Resolve that every video clip you import into the media pool should default to the color space which you define in the dropdown. Text and other generators are not video clips imported into the media pool, and don't get assigned the color space you might expect (hence the mismatch). A way to fix this is to turn the text object into a compound clip, then use a color space transform node to assign the correct color space. There's a helpful video on MixingLight.com where Patrick Inhofer explains the scenario using a greyscale ramp and color bars. You might need to sign up for a free trial of Mixing Light to watch it, though. https://mixinglight.com/color-tutorial/ ... anagement/

WHEW! The Compound clip - CST worked! Thanks! Hopefully this will be addressed in later versions...
Thank you!
