Video & Media Accessibility

Recommended Reading for Media Accessibility

Video and media content offer a powerful medium by which to share ideas and educate and inform people. Addressing the accessibility of video and other media requires attention to both the content itself as well as how the video and media is delivered to the end-user. It is possible to have a very accessible video presentation, but it may be delivered in such a manner that the controls are not accessible or usable by an individual.

Player Accessibility

Media players are available in a variety of plugins and skins that support the playback of media content on Web pages. Accessibility considerations for media players include:

  • Keyboard access to player controls
  • Labels or names for player controls
  • Ability to navigate into and out of the media player via keyboard
  • Support for captioning and audio description

Two accessible media players to consider for use on your websites are the Oz Player and Able Player. Both media players offer support for different media formats as well as content delivered from YouTube and/or Vimeo. Additionally, if captions are included in the original YouTube video, then these players can include that information as they stream the video media.

Oz Player

The CCC Technology Center and CCC Accessibility Center have acquired a site-wide license for the Oz Player that is free for all California community colleges. The Oz Player is an accessible HTML5 player that replaces the standard HTML player controls with accessible keyboard and button elements. This offers individuals the ability to interact with the Oz Player using a variety of assistive technologies as well as standard keyboard commands. The example below uses a video from YouTube and wrapped with the Oz Player interface

Audio/Video Accessibility

Accessibility for video and audio presentations can be supported by including captions and audio descriptions for video and providing a text transcript for audio. Captions are the synchronized text equivalent of audio content from a video, film, television broadcast, live event, etc. Further, captions provide the same information in a text format that is provided through the audio presentation, including speaker identification and sound effects.

Additional information about captioning can be found at the Captioning Key, a resource from the Described and Captioning Media Program.

Audio descriptions are intended to provide blind and visually-impaired users with additional information as to what may be happening on-screen. For instance, a video presentation may include identified speakers or on-screen instructions. If this information is not communicated through the regular audio track, then it is necessary to include this information as an audio description, including directional cues and other on-screen information.

Description Key, a project of the Described and Captioned Media Program, is a collection of best practices and recommendations for producing audio descriptions, including what to describe and how to describe on-screen information.

Transcripts provide individuals who cannot access the video or audio information an opportunity to still engage with the content. Transcripts may be provided for video content, but must be provided for audio-only presentations. Transcripts should include information as to the speakers as well as related informational cues.
