I'm not a heavy user of paid-for software (almost everything I use is open source), but I thought I'd mention this cool video-editing package that Steve Garfield tested at CES. Muvee saves you the pain of editing your video by automatically editing your footage and setting it to music. He writes:
Their software automatically takes your raw footage of movies and photos and makes it into a movie set to music...There are lots of styles to choose from. Mohamed gave me a short demo and then I asked him if I could have muvee make a movie for me with the footage I had already taken on my Canon S400. He brought out his laptop and we loaded up my pictures and video from the previous two hours. Video that I was going to have to edit anyway.
So we loaded in the footage and chose a quick edit style. The music we used is licensed by muvee for demo purposes. I then clicked a button that said make muvee and the software analyzed all the footage, looking at the where it would make the edits...After that I previewed the movie and could make any changes that I wanted. there are a TON of options on how to save your movie, even to DVD. I chose Quicktime, 320x240, 15 fps and saved to a flash card. then I copied the movie onto my Mac for viewing with QuickTime player. Plays great.
