Rotorscoping in AE

Looks cool.
Well, I rather like the effect I get if I dont make the mask fit EXACTLY over the figure. I've found that if I exaggerate the outline a little, I get a bit of squash and stretch, and the animation is a little more dynamic, as otherwise I might as well have just put an effect on the footage. This way I am in effect creating my own animation and just using the footage as a template.
