I just started to grade a small project filmed on a RED Helium.
Working on Resolve 12.5.6 I wanted to do this one in ACEScct. I like to grab stills of every shot in DC2/RG4 before I switch over to ACES, just to have something to compare. Most of the shots looked pretty good through the ACES pipeline, but some shots were looking really strange.
The image through DC2/RG4:
Through ACEScc Rec709:
I hope it is visible with those JPGs. It feels like the red hues are breaking at some point very harsh and then loosing detail. On the vectorscope you can see a straight line on the red line (a small line on the greens as well)
Vectorscope ACES Rec709:
To be honest the footage is a bit underexposed, but this should not happen, should it?
The pure ACES image without ODT does not show those clumpy colors.
Is this related to the new sensor?
Right now I can't work with ACES on this project because I haven't found a way to get rid of those weird colors.
