What WCAG 1.2.2 Requires
Prerecorded video with sound needs synchronized captions, so a deaf or hard-of-hearing visitor gets the dialogue and important sound effects.
Can AccessBell Test This Automatically?
Yes. AccessBell's scanner runs axe-core, which includes 1 rule that catch code-level failures of this criterion:
video-caption— Ensure <video> elements have captions (details (opens in a new tab))
This criterion is included in: WCAG 2.2 AA Checker, WCAG 2.1 AA Checker, ADA Compliance Checker, Section 508 Checker, EN 301 549 Checker.
How to Test It by Hand
Turn on the video's captions and confirm they match the audio and appear on screen at the right time.
Common Failures
- A video has no caption track at all.
- Captions exist but are auto-generated and never corrected, so names and technical terms are wrong.
