This week I got my hands on a PowerMac dual G4 Mirror Drive Door that I will use as a video editing station with iMovie.
When I started iMovie I noticed that it had set the default DV format to be DV-NTSC (probably since I use English as my language). iMovie adjusts the format based on the camera hooked in to the system but as I created the project before I hooked my camera to the computer it used NTSC and I was screwed. I did not find any setting in iMovie to change the default format. I did a search in the manual. I searched Google but could not find anything. So I decided to apply some brute force the application folder. In a couple of minutes I found the setting string defaultVideoFormat that said DV-NTSC. Changed it to DV-PAL and I was good to go.
The file you need to change is located in:
(If you are using some other language than English look in that folder instead)
