Here is my second home movie made with the Kodak Zi6 and apple imovie '08. Youtube now supports 720p HD, but there are some special tricks to get it to upload correctly that took me awhile to figure out. This is from a pocket camcorder. Yes, pocket camcorder are now in HD. I got mine for $160 and there are comparable ones I saw today for only $120. they work amazingly well in good outdoor light, run on 2 AA batteries and require only a cheap SD memory chip. imovie '08 came with my imac but I didn't expect to ever use it until I realized I could get a cheap camcorder. The downside of the pocket camcorders are pretty serious if you are looking for quality video making. The high def doesn't work well indoors unless you use a ton of lighting. There is no image stabalizer built in so you can't really even walk while filming unless you want it to bounce all over the place. But for what it is, this is amazing.
You can't watch it in HD from this website (there is a way to embed it but I don't know how yet). Double click the image and go to youtube. Click "watch in HD" in the bottom right of the movie.
