If you are using Resolve Color Management, how do you go about tagging clips as Rec.709-A in the media pool? The introduction made it sound like this would be something in a right-click fly out menu.

It is...

Are you sure you are choosing color managed in project settings?

Interesting thread ... Apologies if this is an off-topic question, but:

Does this fit in if using a calibrated display and a BM card like the Minimon 4k?

No. For this you grade to 2.4 gamma and then if you want to export for "Mac only" add colourspace conversion node and then choose Rec.709-A as target (also in export options). This will make Mac version (when watched on Macs) look the same (minus inaccuracy of Mac display) as your main master watched on calibrated display.

I'm getting this same issue when using Full Screen on resolve. It's much more saturated... I had to revert back to 16.0, is this a known bug?


Yea, there's some weirdness going on... Full Screen mode is a touch lighter compared to the mini viewer in both Edit & Color pages -- I'm not getting over saturated like you, but there is slight a difference in contrast for me (it's gotta be a bug, I hope).

This may be a correct look as color window compared to QT X had small difference.
Sounds like something is not 100% right and bug.

Hi,

I don't know if this is a bug or intended behavior but when using Rec709-A in RCM and have a logo above my footage in the timeline, the highlights in the footage clip. When the logo is turned off the footage has all highlight detail

Render Cache is turned off

This also happens when converting a clip to a fusion comp

It seems to only happen with Rec709-A.
Gamma 2.4, 2.2 and (Scene) don't have the same issue

I usually finish my projects in FCPX with Motion effects and titles. Would it be right to export from Davinci Resolve using Rec 709-A when FCPX will do the final export?

I'm insecure that Final Cut Pro X will export with the non-DR-matching look from Rec 709 gamma 2.4 baked in?

Rec.709 or 709-A, both brings the same result after export from FCPX.

Thanks. I'm still not sure I understand why FCPX tags final export ProRes 422HQ (mov) files as 1-1-1 when the graded footage used is tagged 1-2-1. Anyone know why?

Because FCPX hasn't a color management? I guess that all imported files FCPX reads like a video with 1-1-1 color space tag and all videos exports with 1-1-1. Or I am not right? Has FCPX a color space export settings? Because Apple Compressor has it. Maybe you need export videos from FCPX via Compressor. (send to Compressor command)

Not sure if you're right. FCPX has some color management, but when it comes to flagging SDR files it does either Rec.709 or Rec.601 I assume. It won't do 'other' gammas.
Appel still insist on 1-1-1 tagging or Rec.709 HD, where it's actually very wrong. Their 1-1-1 tagging uses 1.96 gamma, so this is nothing like todays 2.2 or 2.4 standards. Apple follows old/original Rec.709 spec which was made for cameras not displays. This is huge problem, but no one sees it and give a crap about it.
