In this hands-on workshop, participants will develop a complete understanding of how to make video fully accessible. They will add captions, audio description, chapters, and interactive features to a video using Able Player.


When HTML5 was published in 2014, it introduced a variety of new features that make it possible to provide highly interactive, fully accessible audio and video in the browser with standard HTML markup. To date, no browsers natively support all possible functionality, but Able Player, a free, open source HTML5 media player developed at the University of Washington, does. This session will explore the full array of HTML5 media accessibility features, and will use Able Player to bring all resources together to form a single highly interactive video. Specifically, participants will learn to: a) Caption video; b) Add audio description using two different methods; c) Add foreign language subtitles to video; d) Add navigable structure to videos using chapters, and e) Add interactive features such as clickable hot spots to video using metadata.


  1. What features make online media more accessible and usable to all users.
  2. Various methods for adding accessibility features to online video.
  3. How to setup fully accessible video using Able Player.
