I have used Windows Movie Maker in the past and was very satisfied (heresy!). I am one of those nerds that records stuff I do on my xbox (mainly Halo) and creates movies out of them. I would import large files (~300mb) and do some editing and compress it. iMovie takes a ton longer to do this on my PowerBook G4. Both computers have 512MB RAM so I don't understand the reason for the vast difference. Why is it so slow? Does it do additional things that WMM doesn't? I did a test to see how iMovie works with a 150MB .mov file I had. I imported it (~20min) and then compressed it to about 20MB (~55min). I don't recall WMM ever taking more then 30min to compress many large files together. Why the big difference? Also, when it first gives the estimated time left to compress a file it always says "less then a minute" then slowly but steadily increases the time. The file I wrote about above started at "less then a minute" and got up to "56 minutes." Why such a poor initial estimate? Sorry about being such a complainer. I love my PowerBook. Edit: Wow. That slipped to the second page pretty dang fast. Will no one help me?
