# 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

## Applicability

Any technology.

This failure relates to:

- Success Criterion 1.2.2 (Captions (Prerecorded))
  - How to Meet 1.2.2 (Captions (Prerecorded))
  - Understanding Success Criterion 1.2.2 (Captions (Prerecorded))

## Description

The objective of this failure is to avoid situations in which synchronized media alternatives provide more information than the text for which they are alternatives, but do not provide their own text alternatives to provide access to the extra information. Synchronized media alternatives provide enhanced access to users for whom synchronized media is a more effective format than text. Since they are alternatives to text, they are do not need themselves to have redundant text alternatives in the form of captions, audio descriptions or full text alternatives. However, if they provide more information than the text for which they are an alternative, then they are more than simply alternatives but are synchronized media content in their own right. In this case they are subject to the full requirements of Success Criterion 1.2.2 to provide captions and to Success Criterion 1.2.2 and 1.2.3.

### Expected Results

- If check #2 is false, then this failure condition applies and the content fails these Success Criteria.
