City University of Seattle Library: Accessibility: Accessibility Practices for Audio, Video, and Alternative Formats

Audio, Video, and Alternative Formats

Common accessibility barriers to audio and video content include:

missing description of visual information (such as text in the video) for people who cannot see the video
requiring sight to understand the content of the video
making text in the video hard for some people to see because there is not enough contrast between the text and the background colors

The Web Accessibility Initiative's guide to Making Audio and Video outlines how to make media accessible, whether you are creating it yourself, outsourcing it, or sharing content created elsewhere:

Making Audio and Video Media Accessible
This guide helps you figure out which accessibility aspects your specific audio or video needs, provides project management guidance, and includes requirements from the Web Content Accessibility Guidelines (WCAG) standard.

Audio

Before posting audio, such as a podcast, to your LMS shell consider the following questions:

Have you provided a transcript for users?
If you've posted music, have you provided lyrics?

Creating Audio Content

Video

Before posting videos to your LMS shell, consider the following:

Are the videos 5-10 minutes or less? If they're longer are they searchable?
Do the videos have captions and are the captions accurate?
Have they been embedded into your modules in a user-friendly way?
