Hello, i'm trying to do a really basic thing in After Effects. I want to create a clone effect by creating mask layers but every time I try this the background turns black instead of merging with the other scene. This are two separate videos (with the same scene, obviously) and I am trying with the top one. I can't seem to find any solutions, could anyone please help? Thanks
Nobody can tell you anything without proper system info or other technical details like version of AE, exact details about the comp and footage and so on.
