Video’s Visual-Only Content Never Described in Any Format
1.2.3 — Audio Description or Media Alternative (Prerecorded)
Scenario
Setting
A community forum's discussion thread
What’s wrong
Video with important visual-only information (on-screen text, charts, demonstrations, scene changes) and no audio description and no descriptive transcript.
Example
Here's a real case from a community forum's discussion thread: video with important visual-only information (on-screen text, charts, demonstrations, scene changes) and no audio description and no descriptive transcript.
Why it matters
Blind and low-vision viewers who hear dialogue but miss unique visual information. In this case (a community forum's discussion thread), they are left guessing what the media actually shows.
How to test
Play the video with eyes closed for 30 seconds: if you lose track of what's happening because visual information isn't described, it fails.
How to fix
An audio description or a full descriptive transcript covering all important visual information must be provided.
Outcome
Once corrected, a community forum's discussion thread lets them hear or read what the media conveys.
Who is affected
Blind and low-vision viewers who hear dialogue but miss unique visual information.
