@thekyleguy mentioned via Twitter that YouTube does not do well with HD footage, despite being newly HD and widescreen capable. He recommended blip.tv as a viable alternative.

I decided to compare them head to head, well, to head. I added Vimeo to the mix, as it is my sharing service of choice when publishing work for public display. My little less than one minute video was roughly 70 megs when copied right from the Flip.

Here are the three videos. Keep in mind I uploaded this without any changes at all. This is raw footage, compressed using the Flip’s internal H.264 compression and then the sites do with it what they please to display it. I also did not change the default embed code in any way, despite Vimeo’s delicious method to change the size, color, etc of embedded videos.
I had to change all the embed code to the same size. Since YouTube’s embed code used the size I liked the best (560×345) I stuck with that all around. This post looked awful with three videos of all different sizes. In hindsight this should have been three posts.

The first thing to notice is that the blip.tv player borks my theme because of the width. It plays HD video in the native resolution of 1280×750. I could change that in the code relatively easily, but in keeping with a direct head to head to head comparison, to heck with my theme.

Vimeo

So the Vimeo embed wasn’t HD. You have to go to the Vimeo site to watch it in HD. Odd.
