1.2.2: Captions (Prerecorded)

What it means

Prerecorded video with sound must include captions so people who are deaf or hard of hearing can follow spoken words and important sounds. Captions should be accurate and in sync with the video.

This covers dialogue, narration, and sound effects that matter to understanding.

How to fix it

  • Add closed captions to all prerecorded videos with an audio track.
  • Caption speech, speaker changes, and meaningful non-speech sounds (for example [door slams]).
  • Check timing so captions appear when the words are spoken.
  • Review auto-captions and fix errors before publishing.

Quick examples

  • Good: A training video on the help page plays with accurate, synchronised captions users can turn on.
  • Bad: A marketing video auto-plays with speech but no caption option at all.
  • Good: Captions include [phone rings] when that sound affects what happens next.
  • Bad: Auto-generated captions garble technical terms and never get reviewed.
