Goal
Provide an audio description or text alternative for all prerecorded video content to ensure people who are blind or have low vision can understand the visual information presented in the video.
This guideline focuses on making visual information accessible to users who cannot see the video.
If a video includes important visual actions, context, or scenes that aren’t described in the audio, then an audio description track or alternative text-based transcript should be provided.
For example, if a character silently picks up a key to unlock a door, that action needs to be described so that a blind user can understand the plot.
There are two acceptable approaches:
- Audio description track – a narration describing key visual details.
- Text alternative (transcript) – a written description that includes both dialogue and visual details.
