Okay, first of all, I really liked those clips! Excellent job! Thing with the video though is that even though it looks old, it's not quite "silent movie" old (and again, I don't want to sound like I'm nitpicking, I'm just offering up a suggestion or two; take them how you will).

1.Perhaps you could try fading the borders of the picture to make it look like it was shot with an old-time lens, like this:

2. You could also try mucking around with the frame-rate. Perhaps either a) speed the frame-rate up just a little bit, or b) (and only if there's an easy way to do this, because doing it manually would be a monumental pain in the ass) find a way to remove, say, one out of every four or five frames, to make the movement look choppier.

Again, if it's too late in the game for changes like this, then disregard this post. I also don't want to seem like a nitpicker, I just you guys's edit to be as awesome as possible (because, let's face it, this is a really cool idea!)
