- Success Criterion 1.2.5
- Conformance level AA
1.2.5 · Audio Description (Prerecorded)
Lesson overview · Audio Description (Prerecorded)
In plain language
Prerecorded videos need an audio description track describing important visual-only content.
Who it affects
Blind and low-vision viewers who need spoken descriptions of important visuals.
How to check
Play the video with the described track (or check one exists); confirm on-screen text, actions and scene changes are spoken.
Common misconception
People confuse this with 1.2.3. That one lets you choose between audio description OR a text alternative; this one, at Level AA, specifically requires the audio-description track itself.
