Had a clip that wasn't showing any colour management options under modify|interpret footage.
Source clip had been consolidated via project manager (back in v13 so no colour management then, right?).
So I did a quick test - and it seems that dnx consolidated media has interpret footage colour management greyed out + op1a xavc consolidates is interpreted as rec709 (even though it should have been slog3.cine3gamma).
I *guess* it's taking the colour space from the sequence, rather than the individual clips?
I also see that the consolidate burns in the colour transform IF the General|interpret log footage setting is checked and leaves it flat if it is unchecked.
BUT it appears NOT to match the colour transform as applied in the timeline though (and it's not a simple 0-255/16-235 levels change either).
Seems to me that project managemt consolidation should copy the source clips with the metadata.
Will try and flesh this out with some screengrabs and sample clips if I get some time.
