Take one video and multiply it by another black and white video, to create a masked video, and then overlay this on another background video. For example, in the picture below, the pink is one video, the red is another video, and the silhouette of the dancing girl is another black & white video.
As far as I can tell, I can't do this with Resolume. Is there something I'm missing?
I would imagine that this would be possible if there were a way of "nesting" tracks, so that the results of the multiply operation could be treated as a track.
