Matte or Key?
I’m trying to make a white Shape from Video Generators, give it a soft edge and then use it as a matte. (I’m trying to create a vignette that takes the image away entirely at the edges so I get something that looks like a slide projector) My problem is when I apply a luma key to it the white goes away, but the gradient where I applied the softness to it stays on the screen as a diminishing gray band. I’m sure there is some easy way to do what I want to do without stepping outside FCP, but I’m stumped as to how.
Any ideas?
