hello everyone
I’m trying to figure out where I’m wrong but I don’t see errors:
I’m trying to remove the green screen from two images and combine the subjects on a new background, but what happens is this, any advice?
this is my project:
ok so it took me some time to figure out what was wrong. Turns out the Keyer node doesnt work well in this scenario so you have to use the ChromaKeyer node as in my file and screenshot.
The Roto node is used as a ‘garbage matte’ for the ChromaKeyer. A ‘garbage matte’ is a mask used to “remove” parts of an image from a process. In short, it tells the software which parts of the image we want and dont want. In our case, we want to key Read2 but we dont want the blue circle, only the magenta box. So we add a garbage matte to the magenta box and set it so that everything outside the mask is grabage, i.e. we dont want it.
