Video With Visual-Only Info and No Audio Description Track
1.2.5 — Audio Description (Prerecorded)
Scenario
Setting
A crowdfunding platform's campaign page
What’s wrong
No audio description track/version at all for video with important visual-only content.
Example
<video src="tutorial.mp4"></video>Why it matters
Blind and low-vision viewers who need spoken descriptions of important visuals.
How to test
Check for an audio-description track/version at all on any video with important visual-only content: if none exists, it fails.
How to fix
An audio description track must describe all important visual-only content, using available pauses in dialogue.
<video src="tutorial.mp4"> <track kind="descriptions" src="ad-en.vtt" srclang="en"></video>Audio description narrates visual actions and on-screen content during the video's existing pauses.
Outcome
On a crowdfunding platform's campaign page, this barrier is gone for blind and low-vision viewers who need spoken descriptions of important visuals — they can finish what they came here to do.
Who is affected
Blind and low-vision viewers who need spoken descriptions of important visuals.
