Title: Matching ML Raw to BMCC Film (log) footage
Post by: TKez on April 29, 2019, 08:47:13 AM
I shot some stuff the other day for a project using a Blackmagic Cinema Camera and a 70D for the second cam.
My well thought out plan was that If I brought the 70D Raw footage into Resolve , set the colourspace to BMDFilm and set the white balance to the same as the BMCC camera was set to, the shots should match.
But even with the exposure tweaked to match, the color and tonality is very different.
When I cut the footage from the 2 cams together and drop a BMD Film > Rec709 LUT over the sequence, the shots from the Canon look more contrasty and saturated than the BMCC footage.
The BMCC footage also seems to have a pretty strong green cast compared to the Canon

Has anyone had experience matching footage like this?
Is there a recommended workflow for this or just a matter of matching things manually?

Thanks in advance

I haven't ever used DaVinci resolve. I use Adobe After Effects with the Cinema DNG's from MLVApp to edit the RAW profiles with Adobe Camera RAW. Same with BMCC Cinema DNG's.

It's never straightforward to match the two color spaces though. It requires a lot of tweaking of levels and curves, but overall it should be fairly simple if you know a little about color correcting. I usually have to dial up the magenta/red on the ML canon footage.

My straight out of the camera footage is usually similar to this video: https://www.youtube.com/watch?v=xwB_zvZZSUg
