video-captions
Use when applies to all `<video>` elements and third-party video embeds (YouTube, Vimeo) where the page owner controls the content. Prerecorded videos require `.vtt` caption files via `<track>`. For videos embedded via `<iframe>`, check that the video platform captions are enabled. Audio-only content requires transcripts instead (SC 1.2.1). Video-only content (no audio) requires a text alternative or audio description instead (SC 1.2.3).

# Provide captions for video content
Approximately 15% of adults have some degree of hearing loss. Captions are essential for deaf and hard-of-hearing users who cannot access audio content. They also benefit users in sound-sensitive environments (libraries, open offices), users watching without headphones in public, non-native speakers, and users with auditory processing disorders. WCAG SC 1.2.2 is a Level AA requirement — its absence is a legal compliance failure under the ADA, EN 301 549, and similar regulations worldwide.
## Quick Reference
- Prerecorded video with audio: synchronized captions required — WCAG 2.1 SC 1.2.2 (Level AA)
- Live video with audio: real-time captions required — WCAG 2.1 SC 1.2.4 (Level AA)
- Use `<track kind='captions'>` with a `.vtt` (WebVTT) file for HTML5 `<video>` elements
- Captions must include all spoken dialogue, speaker identification, and relevant non-speech audio (music, sound effects)
- Subtitles and captions are different: captions include non-speech audio; subtitles translate dialogue only
