Color Space and Gamma when exporting From Davinci Resolve

[mabdelfatah]

Hello, I tried to find a clear answer for this but it seems like there is no clear answer

I was wondering what settings should I choose for Color Space and Gamma when exporting from Resolve to DCP-o-matic ?
I have ProRes4444 already color graded full film footage, and Resole project settings is Rec.709 Gamma 2.4

I tried different settings (p3, gamma 2.6, rec709A) but none of them show accurate 100% when played in the player , sometimes blacks are dark/crushed , or gamma is brighter/darker, colors are more saturated, etc

what should be the export settings for color space and gamma to get the accurate look as graded without clipping or color shifts?
and what should be the correct settings after importing the footage to DCP-o-matic?

Thanks!

Stay at Rec.709 with gamma 2.4 in Resolve, and use BT.1886 color conversion in DCP-o-matic. Make sure you use either full or limited range within Resolve (Video vs. Full) AND DCP-o-matic the same. Standard for Rec.709 is Video/limited range.

Thank you! I tried it but in DCP-o-matic player on my monitor it looks darker, is that normal? Should i be expecting it to look the same as my in Resolve? Or what?

In Resolve, it's rec.709 or BT.1886. In DCP-o-matic player, it's a retransformation from DCI X'Y'Z' at gamma 2.6 for 14fL/48cd/sqm.
This is meant for a very different viewing environment, that a common sRGB Monitor can not simulate. I don't know if your Resolve installation is color calibrated. In my experience, DCP-o-matic player comes very close, but if you're picky, you may need to evaluate your DCP in a cinema.

You may load your DCP into Resolve and compare it with your master there.
