WCAG 1.2.2: Captions (pre-recorded)
In European law this criterion is EN 301 549 clause 9.1.2.2 — chapter 9, the part of the harmonised standard that applies to websites under the European Accessibility Act.
What automation checks
One axe-core rule tests failures of this criterion. Our scanner runs it on every page it visits:
video-caption
On top of axe-core, our own browser check a11y-video-no-captions flags <video> elements that have no captions or subtitles track.
What automation cannot prove
An automated test finds some failures of WCAG 1.2.2; it cannot confirm the criterion is met. Whether the result actually works for people — in context, with real content — is a judgement call that needs a human auditor. Nothing on this page is a statement of conformance or legal advice. The full map of what our scanner covers and where it stops is on what our scanner checks.
