Silent Demo Video With No Transcript or Narration
1.2.1 — Audio-only and Video-only (Prerecorded)
Scenario
Setting
A dating app's profile setup
What’s wrong
Video-only content (silent demo, screencast, animated GIF conveying process) with neither a text alternative nor audio track.
Example
<audio src="podcast.mp3"></audio>Why it matters
Deaf people who need transcripts of audio-only media, and blind people who need alternatives to silent video.
How to test
Play any silent video (demo, screencast, animated GIF of a process): if there's no transcript or narrated audio track describing what happens, it fails.
How to fix
A complete, accurate transcript (or an equivalent audio track for video-only media) must be provided and linked right next to the media.
<audio src="podcast.mp3"></audio><a href="podcast-transcript.html">Read the transcript</a>A text transcript gives Deaf users the same content the audio carries, with no video/audio dependency.
Outcome
On a dating app's profile setup, this barrier is gone for deaf people who need transcripts of audio-only media — they reach the same outcome without extra effort.
Who is affected
Deaf people who need transcripts of audio-only media, and blind people who need alternatives to silent video.
