Prior to discovering Vimeo this week, I had not heard of high definition online video.
So I uploaded a rough cut to see what online high def video looks like. I think it looks great. This rough cut clip is taken from a canoe design segment of our upcoming tandem canoe movie. If you view this clip, be sure and click the "full" icon in the lower right corner of the Vimeo page. That will give you the HD screen.
