How to upload video

Nope, can't get the video to upload. Any advice anyone? I've transfered the video from iPhone to iPhoto and then tried:

- saving in iMovies
- saving in Quicktime

and then either uploading to Blogger direct or via You Tube. But none of that seems to work. I think my problem is that I'm not saving to the right file type. But can't find how to do that. HELP!
