I have some footage shot with a green screen and stupid me didn't pay attention to the shirt I had on which on the center of the shirt has some green. So naturally, I have a hole in my chest when keying. My solution was to create a mask around it and then feed it to the "core matte" input on the keying node. While this does work, it changes the color of the part on my shirt.
My question is: How do I prevent color change if this is the correct way to fix it? If it is not I'd like to know the best solution.
Thank you so much in advance for taking the time to help!
