Add descriptive audio tracks in Compressor
You can create video content for people who are blind or low vision by adding descriptive
audio tracks. Descriptive audio tracks narrate important visual details that can’t be
understood from the main soundtrack alone. Compressor can extract the descriptive audio
tracks from audio files like WAVs or AIFFs, or from video files like MOVs. You can embed
descriptive auto tracks, like language tracks, in the QuickTime Movies, Apple Devices, and
MPEG-4 formats. For more information about descriptive audio, see the American Council
of the Blind’s Audio Description Project website.
