Tips for Making Web Video & Audio Accessible
Updated: June 3, 2019
How do you tackle making your web content accessible to everyone? What about media-rich content, like videos and audio recordings?
Janet Sylvia, leader of the University of Georgia’s Web Accessibility Group, helps answer those questions in our webinar, 10 Tips for Creating Accessible Web Content with WCAG 2.0. The following augmented excerpt from her presentation focuses on how to make your web video and audio content WCAG compliant.
Accessible Audio Files
If you use audio only, like a podcast or audio lecture, we must provide a text transcript of the spoken word. And that text transcript should be a document that’s accessible, preferably HTML, but it can be an accessible document of another format, such as .TXT.
Accessible Video Files
If you provide video without audio, you need to provide a video description. This is a text description of the key visual elements that are required to comprehend what’s taking place in the video. The text can be read aloud by a screenreader. Alternatively, you could provide an audio recording of the video description to be played by a user with low or no vision.
If your video has audio, you must provide synchronized closed captions, the text transcript, and the video descriptions.

Don’t Auto-Play Video
We must provide an option to turn off all multimedia on a website or in an online course. This means that the Pause and Stop buttons must be keyboard accessible, and the controls need to be screen reader accessible.
Imagine a blind user navigating your page and getting bombarded with an auto-playing video that they can’t stop. That’s a UX nightmare!
Accessible Media Player
Not all media players are accessible. In general, Flash is considered outdated in terms of web accessibility. HTML5 handles keyboard controls, labels, and accessible design features much better.
In higher education, it’s very common to put content on YouTube. YouTube’s default media player is now HTML5, which makes it a much more accessible choice for web video.
