When iMovie creates a new project, it defaults to NTSC unless you have a PAL camera connected. If you don't have a PAL camera (say you want to edit a DV Stream produced by an InterView device for example), but want to create a PAL project, there's no option in iMovie to do so. Of course, there is a way. Here's what to do:
iMovie Project File
External Version: 2.0
Version: 0.9
VideoStandard: NTSC
ProjectSelection: 0 -1 -1
PlayHead: 0
AudioTrackMute: 0 0 0
