Aftereffects Keying in ACEScg


(Peter) #1

Hello,

although it’s far from comfortable, I am using an ACES workflow in Aftereffects for at least one year. With the OCIO plugin.

Again and again I face the same question: Is Keying in ACEScg a good idea? Or is Keying in Linear-Space a good idea at all? It’s always a little unpredictable what happens. I got a feeling, that the Keylight plugin is not really prepared for linear greenscreen footage. Or at least optimized for a Rec709 workflow.

So can someone help me with:

  • Can Keylight handle 32Bit linear data at all? Does it see values above 1?
  • Is ACEScg a good workingspace for such work?

Thanks for any ideas!

Peter
