Clean Up Green Screen Spillage In Car Scene

[aidan_9644]

I have a scene I shot in a car where I tapped green poster board to the windows to so I could make it look like the car is driving. The problem is there is some green light reflecting off the poster board into the car. So besides the actors everything in the shot has the driving footage over it. I was wondering if there is a way in post to reduce the green reflection or make it so the background footage stays only in the car windows.

Is the camera shot moving?

The Ultra Key effect includes Spill Suppression settings that can help reduce green spill by desaturating affected areas.

To further refine the key, consider using an effect mask with Ultra Key. This allows you to isolate the keying to specific regions—like the area around the windows—so the rest of the scene remains untouched.
