I'm trying to overlap two shots into one, but only in one specific spot. I tried using the pen tool to cut out the area that I want the figurative "hole" to be where the other video would show up from, but I'm not sure how to make the hole or if it is even possible.
P.S. I am a After Effects n00b as they say.
Save yourself a lot of headache and simply type masking in the search help field at the top right corner of the app. Read up on masking. It's really simple and basic skill you will need to understand do you have any luck at all building composites.
