iMovie 3 introduced a clever thing: when you saved a project, it also created a QuickTime reference movie of the contents of your timeline, effectively creating a QuickTime movie of your movie. Being a reference movie, the file itself was just a pointer to the various media files in your Media folder, but you could drag the refernce movie into iDVD, for example, as a quick and easy way to import a movie without going through iMovie’s Export/Share process.
Projects in iMovie HD, however, are stuctured differently. Instead of having a single project file, a Media folder, and a reference movie, everything now is bundled into an iMovie project package — one file that acts like a folder.
So what happened to the QuickTime reference file? It’s still there… you just need to know where to find it:
- Control-click your project file (it will look something like, “iMovieTest.iMovieProject”), and choose Show Package Contents from the contextual menu that appears.
- Open the Cache folder.
- Locate the file named “Timeline.mov”. That’s the reference movie.
You can then copy the reference movie to another folder, or drag it into iDVD.
