Exporting to Quicktime
Once you have exported your iMovie to QuickTime, you can change the file size if it’s larger than you’d like. Although there are special programs like Media Cleaner 5, the QuickTime on your Mac or PC will do an adequate job of making files smaller. But first you need QuickTime Pro. It’s a simple online upgrade if you have the free version of QuickTime. Go to Edit, Preferences, Registration, and click Register Online. The nice thing about QuickTime is that it works on both PC and Mac.
