Black Magic color space in Nuke

PostFri Oct 16, 2020 11:03 pm

I'm sure this has been addressed already, but I haven't found my answer yet. Input is greatly appreciated.

A client has switched cameras and are now using all Black Magic Cinema 6K.

Our conform process takes the raw footage and converts it to raw dpx files for comping.

We bring them into Nuke, raw. Then we drop down an ocio color transform node. Ordinarily we would select, based on the camera, something like alexaV3logc, or slog3, or cineon, but none of those look right, and we don't have a "black magic cinema" color space.

Since we will be rendering CG to integrate with the footage, we need to create exrs with proper color so that CG can match what it should actually look like.

Is there something else I should be using in Nuke, or downloading so that Nuke displays proper looking footage?

I'm not an expert on this but I think a solution would be to do the convert to dpx or exr in Resolve.
There you'd be able to set the BRAW files in Alexa space and gamma from the raw tab (latest beta version).
Then output all as seperate files to whatever fileformat you'd want.
