Yeah, doesn't look bad. Out of curiosity, if you turn the iphone sideways during the clip, what does it do to the vimeo display? It stays vertical like it is here, I'm guessing? Which suggests that you want to shoot all vertical or all horizontal, yeah? (sorry, tech questions)
I'm not quite sure I understand your question. If you shoot vertical on the iPhone, when you email it, it will be vertical on Vimeo. Same with horizontal.
