Hey Shed,
It all depends on how big the file is. It prolly is too big to email it efficiently since it's 7 minutes long. If the file is on your computer and you have something like Windows Movie Maker, you can cut some of the scenes to make it shorter. I'm not sure how it will handle compression, so the file might actually come out bigger than it was. Right click on the file and go to properties, in there it will show how big the file is. Anything over 10-30 megs is usually too big to send it email.

Hope that helps a little
