Exporting to Dolby Digital Professional (AC-3) Files
Dolby Digital Professional format (also known as AC-3) is a very common compressed
audio format for DVD-Video discs. AC-3 programs can deliver 5.1-channel surround as
well as a variety of other surround configurations. This format is frequently used to encode
stereo files to greatly reduce their file size.
Note: Dolby Digital Professional (AC-3) encoding is available only on computers that also
have Final Cut Studio installed.
