Well, I'm a creative person, I'm fairly saavy with software and I enjoy reading technical manuals. So I don't think I'd have a problem learning the software. I especially like the idea of layering videos and audio. Perhaps for some of my more straightforward home movies, FCE would be overkill, but I also love to mess around and create stuff. Perhaps I'll go to the bookstore and check out the books on FCE to see what it can do.
I'm pretty sure you can't do the following in iMovie but can FCE handle this?:
1. Could I take a video and change it's colors - make it all hi-contrast with say white and purple as the main colors, for example? Think of the iPod adds that are almost animation.
2. If there's a portion of the video I like, can I zoom in on it and crop out the surrounding stuff?
3. You mention picture-in-picture and splitshots. Can I take pieces of different vids and lay them out onto one canvas so they all play at the same time, say in different corners of the image?
Thanks!
