One of the first music video's I've seen that is shot completely sideways for a 9:16 aspect ratio. Not uncommon for cellphone videos, but rare for produced videos

vimeo.com -> adjacent videos are other rotations of the same video

Ramona Falls - Clover (9:16 edition) from blair neal on Vimeo.

The idea this is not just a gimmick but a very possible near-future market need made me break into cold shivers. 'Yes, I need this for 4:3, 16:9, 21:9, 9:16 and 720x80 swf.'

It is easy to pass the idea off as a gimmick, but it is unusual that portrait style videos haven't been seen very often yet...i think their time is coming with all of these moveable/rotatable screens we have now..ie cellphones and iphones. It would be an editor/directors nightmare to have to make videos for all of those different aspect ratios though..aspect ratios are annoying enough as it is
