1.2.5Audio Description (Prerecorded)
Level AAPrerecorded video must include audio description that explains visual-only information during pauses in dialogue. Unlike 1.2.3, a full text alternative can't substitute for this -- it's a stricter AA requirement. Video where the soundtrack alone already conveys the visual content, such as a talking-head interview, doesn't need extra description.
