[AE} Keylight Chattering Hey all. Happy New Year!

I’m working with Keylight and some well-shot ProRez 422 footage. I used to be able to pull perfect keys with Keylight in a few steps. Now I’m getting all this noise in the blacks.

I’ll set the Screen Colour, adjust the Clip Black and Clip white and be 90-percent there. Except I’m getting unacceptable chattering in the blacks. I look at the combined matte and there’s NO noise in the white area at all so I’m not sure what’s causing the chattering.

Interestingly, if I select “Intermediate Result” the chattering goes away completely, it’s only when “Final Result” is selected that I see it. Of course, with Intermediate result I’ll loose all the edge adjustments that I’ll eventually need.

Any clues?
