Q: “How do I prepare my movies and pictures for use in iDVD?”
A: iDVD accepts movies in QuickTime format, which is supported by most video editing and creation tools. Still pictures can be any QuickTime-compatible format, such as files with PICT, TIFF, or JPG extensions. If you’re using iMovie 2, there’s even a special option to save your movie in the format that’s correct for iDVD. In iDVD, movies are converted into MPEG-2 format just before they are written to the DVD disc.
