Hello.

So I ran into this problem where I get lines around my matte holdouts. I did render with depth of field, but that wasn't a problem in earlier scenes.
Even when I made a test with a simple cube in a new scene, I got these lines.

Does anyone know how to solve this?

Thanks regarding

Zero the anti-alias when you render the matte? (Try box filter)
Load your animated matte into After Effects and apply the matte choker.

Thanks for your response!

Where can I find these settings? Are they in the karma rendersettings node?
