People who are blind, people with low vision who cannot see the screen, as well as those with cognitive limitations who have difficulty interpreting visually what is happening within Video content will often use audio description of the visual information. The Audio description of video provides information about actions, characters, scene changes, on-screen text, and other visual content.

For further information on Audio description accessibility please refer to the WCAG website here

The opportunity to include the audio description track within your Vudoo videos is available to ensure you are able to provide people who are visually impared or blind access to your video content. Once the track is uploaded, the viewer will have the option to select this function on the video. The Audio Description file must be previously created prior to this process, the Vudoo platform does not create the audio description for videos.

Tip: The audio description needs to provide contextual information relating to what is happening on-screen as well as the original/default track in one audio stream
