1.2.2 · Captions (Prerecorded)
Lesson overview · Captions (Prerecorded)
In plain language
Every prerecorded video with sound needs captions that include all dialogue and important sounds.
Who it affects
Deaf and hard-of-hearing viewers, and anyone watching video without sound.
How to check
Play each video: turn captions on, verify they exist, match the speech, name the speakers, and include important sounds.
Common misconception
A transcript alone does not meet this rule. Captions must be synchronized with the video, not just available as a separate text block to read afterward.
