Jason McGivernphotoshop layer as mask?

So here's what I've got going on now. Please advise on a better way to do this.

I want three independent, animated panels to act as masks over a piece of video - much like a comic book. Normally I would think about adding masks to the video layer in AE, but I want grunged/frayed edges.

So I downloaded some nice brushes for photoshop and created my edge.

The in AE I set up the following for one panel test:

1. GrungeFrame (a thin fuzzy border) - Mode> Overlay - Parent> Rectangle

2. Rectangle (this would normally be the mask)

3. VideoFootage - TrkMat> AlphaMatte "Rectangle"

This works nice for one panel, but obviously I can't add more to the same video footage with this method, I assume you only can have one layer for your TrkMat. So there must be another solution. I think pre-composing and adding 3 720p footage layers would kill performance?

Any help appreciated.

Why don't you split your video layer to add the new track matte? Works like a charm.
