This resource describes (pun intended) WCAG requirements and "best practices" beyond requirements:
Audio Description of Visual Information -- in Making Audio and Video Media Accessible
https://www.w3.org/WAI/media/av/description/

It includes several different options for providing description of visual information based on the situation -- e.g., existing video without space in the audio to add audio description of important visuals.

It also links to important guidance for new videos:
Plan for audio description of visual information
https://www.w3.org/WAI/media/av/av-content/#plan-description

Hope this information helps!

If you have suggestions for improvements to this page (or others), there are links to GitHub and to an e-mail address under "Help improve this page" near the bottom of the page.

Best,
~Shawn

There is only one version of the video and it has the AD embedded in it. There is a button in the player toolbar to turn the AD on and OFF. We had to do this because most of our videos have audio description but there is never enough gap to insert AD into the audio track and we didn't want to have to host and serve up two versions of every video.
