I am trying to figure out how to shift the x , y coordination of a video. Like the attached pic. Video A is smaller than Video B. and I want to position Video A on top of Video B at any X, Y position on the 2D plane. Anyone knows how to shift x, y? I know I can jit.sissor Video B and Video A in many pieces and jit.glue them together. But is there a simple way to do it?
