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..
