I created a perspective corner pin tracker in After Effects. I selected a target, and applied it. Unfortunately, the target is not of the same aspect ratio as the virtual rectangle that I tracked.Therefore, it is horizontally scaled. What I want to do, is correct the scaling and position, within the corners. When I resize the target layer, init expands beyond the corners.Which makes sense, but it it not the sense I'm looking for. What would be my strategy?

Pre-comp the replacement layer (using the option to keep all the settings in the outer comp), and match the aspect ratio of the pre-comp to the rectangle you're tracking. Then adjust the replacement layer so that it fills the comp as you wish.
