1.2.5 Audio Description (Prerecorded)
Manual verification
How to validate 1.2.5 by hand
Check that prerecorded synchronized video provides audio description for important visual information not already conveyed by its soundtrack.
Start with the extension result
Reopen the reported URL and reproduce the same state (for example, after expanding a menu or submitting a form). Use the result’s Highlight action when available, or its affected-element details and CSS selector, to find the reported content. Apply the checks below to that content and its context. If the element or state has changed, rescan and record that difference before deciding whether the finding still applies.
- Watch the video and note meaningful actions, scene changes, on-screen labels, and visual relationships absent from dialogue.
- Enable the audio-description track and listen through the same moments; determine whether it describes those details during natural pauses.
- Check that the description can be selected and remains synchronized with the video.
Evidence to record
Record the timestamp and missing visual detail, or confirm the description makes the action and context understandable without seeing the screen.
Scope and exceptions
This criterion specifically requires audio description for prerecorded video; a transcript alone does not satisfy it. Check the normative exception for media where all visual information is already conveyed in the audio.
Record the review outcome
- Confirmed: the recorded evidence shows the requirement is not met in the tested page state, and no applicable exception explains it.
- Not reproduced: the reported issue is absent in the current state. Record the URL, state, and affected element you checked; this does not prove other pages or states conform.
- Needs more review: evidence is incomplete, the content requires human judgment, or an exception is uncertain. Record what remains to be checked instead of treating it as a pass.
