Back to Success Criterion 1.2.2 Captions (Prerecorded)
Contents
Status
Description
This test checks that prerecorded synchronized media (almost video) contains captions, which are a complete substitute of the audio content.
Background
- Captions (Prerecorded): Understanding SC 1.2.2
- G93: Providing open (always visible) captions
- G87: Providing closed captions
- F8: Failure of Success Criterion 1.2.2 due to captions omitting some dialogue or important sound effects
- F75: Failure of Success Criterion 1.2.2 by providing synchronized media without captions when the synchronized media presents more information than is presented on the page
- F74: Failure of Success Criterion 1.2.2 and 1.2.8 due to not labeling a synchronized media alternative to text as an alternative
Assumptions
- The synchronized media is not a media alternative for another media
- The test does not check for programmatic determinability of the media alternative or a reference such as "The description can be found in text below" from the short text alternative of the video to it.
