Yeah, the TFSource made me even more hyped about the Bruticus set too.
It's pretty simple doing stop-motion really, I used to make stop-motion lego movies with my friend, on an old VHS camera lol.
You have to have your camera on a tripod and position the figure, take a still frame or very short shot, pause recording, move the figure slightly, take another shot, and repeat for a LONG time. I imagine the hardest part is keeping the figure stable so it looks good and doesn't move TOO much. But because you're taking series of still frames or short shots and moving it between them, the human hand will never be visible, if done right.
It is too bad about TFSource sort of taking over Peaugh's channel... in more ways than one. As you mentioned we may never see any more of those cool stop-motion videos, and they're actually the ones I'm boycotting ever since the whole FP Snowman fiasco.
I don't think we're allowed to talk about that in the regular forum, hopefully I'm safe here.
