It was a lot, but I wouldn't call it work. It takes me most of a weekend day to edit down to 10 minutes or so of usable video, but I find it to be quite enjoyable. I'm not very artsy so this has turned out to be a nice way to be creative. Given I had zero experience with video making beforehand, I would say iMovie is a remarkable piece of software for its ability to take you from zero to enjoyable videos easily and quickly. Now if I could just go back and "fix" all of the poor video camera work, then we'd really have something!
