You can use these movie and graphic formats in iDVD:
Most video or image files supported by QuickTime (see the list of unsupported QuickTime formats below)
16:9 widescreen formats
AAC, MP3, and AIFF audio files
Any format from iMovie: DV, high-definition video (HDV), MPEG-2 SD, MPEG-2 SD, MPEG-4 SD, MPEG-4 HD, and AVCHD
High definition video is converted to work with the format of your project. iDVD supports using 16:9 widescreen video; therefore, when your DVD plays on a DVD player that supports widescreen format, the footage appears in its original aspect ratio.
The following video and image formats are not supported in iDVD:
Copyrighted or protected videos.
Movies saved in thousands of colors using the “none” compression setting in iMovie.
48-bit color images (16 bits per color). To use source files in one of these formats in iDVD, save them in a supported format.
Aurora uncompressed files. For best results, export Aurora clips as DV-format video before importing them into iDVD.
QuickTime VR, MPEG-1 or MPEG-2, Flash, streaming or encrypted movies, or QuickTime spanned movies. You can’t add MPEG-1 or MPEG-2 files to an iDVD project because they don’t contain standard video tracks.
QuickTime Fast Start movies. (Fast Start movies are intended for Internet playback.) When saving a QuickTime movie for use with iDVD, click the Options button in the QuickTime Export dialog and make sure that the “Prepare for Internet Streaming” checkbox is not selected.
Note: You can add any type of file to the DVD-ROM portion of your DVD so that viewers can copy the file to a computer. Viewers can access these files only when viewing the DVD in a computer, not a DVD player connected to a TV.
