To create an accessible video review the resources below.  Alternatively, videos can be submitted to ATI for captioning and transcripts by submitting a Request Services Form.

To learn more about creating accessible multimedia content, please review the following:

 

What is Accessible Multimedia?

 

Making multimedia content accessible benefits all learners (e.g., video streaming in noisy airport). Nonetheless, it is especially beneficial for individuals with hearing loss, those who speak English as a second language, and/or those with learning/cognitive challenges. The World Wide Web Consortium (W3C) outlines a number of different success criteria for meeting WCAG 1.2 (Provide alternatives for time-based media)*.

Accessible audio and/or video content should have the following (see Accessible Media for examples):

  • Transcripts
    • Transcripts are required for audio-only content like podcasts. For videos, it is strongly encourage that you post a copy of the transcript along with the video, but it is not required.
  • Synchronized, accurate captions
    • Synchronized, accurate captions are required for videos (with audio) where it is important that the viewer also follow what is being shown visually.

NOTE: Although the video does not have synchronized captions, the text transcript matches the dialog word-for-word. Furthermore, the inability to see the visual imagery would not impact the end-user’s understanding of the content (For more information, see Examples of Success Criteria for Captioning Prerecorded Video*)

  • Audio descriptions
    • Audio descriptions are required when the visual imagery is important to understanding the content presented in the video

 

Choosing Accessible Video Players

 

Creating accessible multimedia is more than just captions, transcripts, and audio description, it is imperative that the player used to deliver the multimedia content be accessible as well. Accessible video players show support the following:

  • Video buttons and controls should be accessible without use of a mouse
  • Video controls should be announced properly to a blind person using screen reading software (e.g., JAWS, NVDA)
  • Support for closed captions
  • Support for audio description (nice-to-have, but not required)
  • Interactive text transcript (nice-to-have, but not required)

Examples of Accessible Video Players

  • Fully Accessible Video Players
    • OzPlayer (AccessibilityOz), See OzPlayer* for more information.
    • AblePlayer, See AblePlayer* for more information.
  • Keyboard accessible with support for captions (Neither supports audio description unless it is burned directly into the video)
    • YouTube (also supports text transcripts)
    • Vimeo
    • Kaltura

 

University-Supported Lecture Capture Solutions

 

Lecture capture tools allow instructors to digitally record lectures.  The lectures may include audio, videos, PowerPoint slides, and screen capture into a single video for instructors to make available online for students. The following resources cover lecture capture features for solutions supported by Mason:

Kaltura Capture Desktop Recorder

Third-Party Lecture Capture Solutions

PLEASE NOTE: While some 3rd-party solutions may be in use in specific academic departments, they are likely not broadly supported by the university. Please contact the ATI for questions on how to ensure content produced using this tools can be made accessible.
