Audio Formats Not Supported by the DVD Specification
If you import an audio format that is not supported by the DVD specification,
DVD Studio Pro automatically uses the embedded AIFF encoder to transcode the audio
file into an uncompressed AIFF format file. For example, if you import an MP-3 file (a file
format that is not supported by the DVD specification), DVD Studio Pro creates an AIFF
file from the MP-3 file and that is what is used by your project.
Note: Because an AIFF file is not compressed, its file size will be substantially larger than
the original MP-3 file. If disc space is an issue, you can use the AC-3 encoder in the
Compressor application to transcode the AIFF file to the Dolby Digital AC-3 format. See
Dolby Digital AC-3 Audio
for more information.
Using AAC Audio Files from the iTunes Store
DVD Studio Pro is able to import and use AAC format audio files purchased from the
iTunes Store as long as the computer you are using them on is authorized to use them.
If you import iTunes Store files that the computer is not authorized to use, DVD Studio Pro
plays silence when it encounters those files. Additionally, if you select and try to play
an iTunes Store file that the computer is not authorized to play in the Audio tab in the
Palette, DVD Studio Pro plays silence. As with MP-3 files, AAC files are converted to AIFF
files.
