Hasta La Motion!

Hey all, I’m a 3D student and I’m working on a special effects projet where I have to deform a girl’s reflection in a mirror. Now the projet is filmed with an HD camera and I’m trying to find a way to modify this girl’s reflection in After effects.

I’ve tried the liquify tool and the results are a little dissapointing because I cannot animate the map right because she rotates her head alot and the map does not deform in the way I would like without going frame by frame..all in all it isn’t working out. For now I’m doing it frame by frame in Photoshop but it’s a real challenge to get everything to fit perfectly and it’s taking way too long for the time I have!

I was hoping to find a way to make it work in After Effects.. Do you guys have any ideas?
