Media chapters available

Supplemental requirement

Audio or video that lasts five minutes or longer can be navigated by chapters.

Except when the media is a piece of music that the composer has not divided into movements.

Research is needed to determine the length of time that triggers the chapter requirement and whether this threshold varies for different languages. If you are aware of research in this area, please email public-agwg-comments@w3.org.

Tests

Procedure

For media that lasts five minutes or more:

  1. Play the media.
  2. Check that the media is divided up using chapters.
  3. Check that the chapter titles have descriptive names which are suitable for their content.
