Masking Transition - After Effects AMV Tutorial

In this tutorial I show how I did the masking transition in one of my edits. Have a mess around with everything, keep trying on your own, and yeah good luck. This was a simple tutorial but takes a lot of time to perfect it. If you have any questions feel free to ask.
