Video Accessibility

I’m working on a new web site that will be live for the next two or three years, hence I’m keeping an eye on both versions 1.0 and 2.0 of the WCAG guidelines. One of the things that has been requested is embedded videos (similar to YouTube) within relevant pages as opposed to having a standalone video section.

Thinking about embedded video meets accessibility and looking through WCAG 2.0 I’ve come up with the following:

To meet Priority One guidelines

• Provide a full text based alternative to the video, i.e. a transcript plus a label explaining, more or less, “there’s a video and this is the transcript of it”.
• Provide synchronised on screen captioning replicating the dialogure and important sounds in the video.

To meet Priority Two (our goal) guidelines

• Provide synchronised audio description (noting changes of location, identifying speakers, etc.) in the gaps in the dialogue of the video.

To meet Priority Three guidelines

• Provide an extended audio description that pauses the video in order to create room for extra information to be relayed aurally.

Does this agree with everyone else’s interpretation of the guidelines?
