- put the two videos on two different layers

- select the pan and crop on the top video (a square thing)

- make sure mask is enabled and the position is at the start (or else it will become a keyframe)

- then draw a box around the half you want to keep (make to draw one line at a time and press the box you just created before starting a new line)
