FCPX: When applying the keyer to green screen, is there a way to change the resulting color from black to another color (cream, blue, etc)?
Currently working on a project where I shot various video tributes in front of a green screen. When using the keyer in FCPX, the resulting image is represented by a black background instead of a green one. I'd like to change that color to blue, tan or something else so that when I apply a picture in a portion of the background, the remaining background looks fine. More specifically, I plan to put images over the right shoulder of each person in the video. The image will only take up about 1/4 of the background and the rest of it currently just looks like a black screen. Thanks in advance for any advice.
