I have rotoscoped an image, but I would like to remove it so that a different video layer can show underneath instead, what is the best way to invert the rotoscoping so that the image can be removed instead of the background?
Hi, there are several ways: if it's a mask/masks set the mask/s to Subtract or place a layer of the footage underneath your roto and set its "TrkMat" to Alpha Inverted (if you cant see the Track Matte box in your layer press the Toggle Switches/Modes box at the bottom of your screen. Then add your different video underneath.

What Towerguy said. Or drag in an Invert effect and set it to Alpha.
I always do my roto separately from my footage on a solid as a track matte. That way I can affect the matte without affecting the underlying footage and vice versa.
It worked !! Thanks a lot 🙂
