iDVD '09 (7.x): About preparing QuickTime movies to work with iDVD
If your video editing application can export to QuickTime, you can create movies that can be used in your iDVD project. iDVD supports most video or image files supported by QuickTime. MPEG-1 or MPEG-2 files, QuickTime VR movies, and movies with sprite or Flash tracks cannot be added.
QuickTime movies smaller than the standard DVD size of 720 x 540 pixels (NTSC) or 768 x 576 pixels (PAL) are scaled to fit the DVD window, which can decrease the image quality.
For best results, in the QuickTime export settings of your video editing application, choose NTSC-DV with a frame rate of 29.97 or PAL-DV with a frame rate of 25. Choose No Compression for audio, and set the sample rate to 48 kilohertz.
Note: You can drag a QuickTime movie file to the audio well in the Menu Info window or in the slideshow editor. iDVD uses the first audio track in the file as a soundtrack for the menu that is open or for the slideshow and ignores the video. For more information, see Related Topics below.
If you share an iMovie HD project as a QuickTime movie using the Full Quality option, iMovie HD doesn’t include chapter markers in the QuickTime movie.
