Don't let anybody ever trick you into thinking stop animation is easy. I was like, yea, I'll do that shit, fuck it, can't be that hard, I've done it before. Man, it wasn't that it was the hardest thing ever, just really goddamn tedious.
Don't get me wrong, I think it turned out fine, it just took a week longer than I originally intended, and encompassed an entire two weeks of non-stop work. For 30 Seconds.
I actually did cut the shoe and played that in reverse and animated the "Robots" myself, using photos. Instead of using a convenient compositing program like After Effects, I decided to do it frame-by-frame in Photoshop and PaintShopPro. And that's the last time I'll ever do that. Much harder and tedious.
