    Beginner question about masking

    kurazi Level 1

      I am new to after effects and have created a simple small video that just has a laptop and a background. The laptop screen has fish swimming from the right side of the screen to the left and off the screen so it looks like they disappeared. I need to mask the laptop screen so I do not see the fish animations slide off the left hand side of the screen. How would I create the mask so it only shows whats going on within the laptop screen? Thanks in advance
