WCAG 1.2.5 Audio Description (Prerecorded)
Level AA
Pre-recorded video must include an audio-described track that narrates important visual information not already conveyed in the main audio.
Common failures
- Tutorial videos rely on "click here" with no spoken description of where "here" is.
- Visual-only branding moments (logos, on-screen names) aren't described.
How to fix
- Script a separate AD narration and mix it during natural pauses in dialogue.
- Where re-recording isn't possible, provide an extended audio description (1.2.7).
