Masking an Effect, not the layer (Chroma Key)
So I need to mask a Chroma Key, it isnt typical where someone is in front of a green background. It is the opposite. A green square in the scene with people crossing, like the typical replace a computer screen with another shot. Masking the layer kills everything outside the mask, not just the key. Need to mask only the effect, but that isnt something I can find in AE.
I know a workaround is to layer the footage back on top and mask it to cover areas that need the effect masked, but using 8K red files, I am adding a lot more pixels to process. I would rather just mask the effect region…Thoughts?

Hi, try this:
Apply keylight 1.2 to your footage layer
then, in the layer panel, twirl open Effects/keylight/compositing options and click the little + sign
it will then pop up a Mask Reference Point underneath – which you can chose to be the mask you drew.I think that keylight should then just effect the mask

This is called a Mask Reference. Here’s the documentation and a quick tutorial:
