Rule ID Video 4
Definition Live and prerecorded video with synchronized audio (i.e. a movie, lecture) using the video element must have synchronized captions.
Purpose
  • Synchronized captions provide a means for people who cannot hear the audio content of a video to understand the audio content of the video.
  • Some types of learning disabilities affect auditory processing, captions provide an alternative way to understand the audio content of a video.
  • This rule covers the requirements of both WCAG 2.0 Success Criteria 1.2.2 and 1.2.4, and therefore covers both live and prerecorded video content.

Techniques

  • Use open captions to include the captions as part of the video.
  • If closed captions are not support, use open captioning to include captions as part of the video.
  • Open captioning is the only way to insure that captions are available on most cells phones and tablet computers connecting through wireless services.
Manual Checks
  • When captions are enabled on the media player, verify the captions are visible.
  • Verify that the captions accurately represent and are synchronized with the speech and sounds in the video.

Column Definitions

Element Identifier
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
Element Position
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
