Accessibility in Videos

It is always important to keep in mind the many ways in ensuring that everyone has access to the content you create. One can broaden the usability of their videos for anyone at different times by providing captions, transcripts, or audio descriptions. This article will provide you with an overview of what captioning is, how it supports learning, and the technical aspects of how to add captions to recordings using tools currently available at the University of Windsor.

What is Captioning?

Captioning is the process of using time-synchronized text to convey all spoken content from television, visual screens, or any other visual display. Additionally, captioning incorporates non-speech descriptions that articulate sounds like indistinct or background speech, music, and even dialogues. The benefits of captioning lie in its ability to offer additional support in numerous ways, which include:

To gain a better understanding just how important captioning is in everyday life, watch this 3:30 minute video produced by the Collaborative for Communication Access via Captioning Organization called “Don’t Leave Me Out!”.

Why should you include Captions in your Videos?

Under the Accessibility for Ontarians with Disabilities Act (AODA) guidelines, all internet websites and web content must conform with the World Wide Consortium Web Content Accessibility Guidelines (WCAG) 2.0 Level A and Level AA requirements. WCAG 2.0 is an accessibility guidelines for organizations to comply with in order to ensure every element on their website and web content are as accessible as possible to everyone. The key guideline that applies to video content requires captions be provided for all pre-recorded audio content. You can learn more about the recommendations for implementing accessibility principles by reviewing the WCAG 2 Checklist.

Accessible Video Sharing Platforms

Currently, there are two platforms that are provide automatic captioning and are accessible to University of Windsor students and staff: Microsoft Stream and YouTube. Both platforms include functionality that improves the accessibility of content for users such as auto-generating/editing/downloading captions and transcripts. While other platforms are used within the University community for sharing video content such as uView and Blackboard Collaborate Ultra (Virtual Classroom), these platforms required the user to create and to upload their own caption files from a source outside of the platform, which limits the accessibility of the platforms for sharing content which is mindful of the AODA regulations for captioning recorded videos. In order to help users determine which platform is best suited for their needs, a brief summary of key differences has been provided below.

Considerations Stream YouTube
Blackboard Integration

Videos uploaded to Stream can be shared within Blackboard either using a link or by embedding the video. For step by step instructions on embedding, please review the Embedding Microsoft Stream Videos in Blackboard article.

Videos uploaded to YouTube can be shared within Blackboard using a link, by embedding the video or through the Mashup tool available within the content editor in Blackboard.

Security and Privacy

Access to videos uploaded is limited to the company or organization (ex: University of Windsor) when using the default permission setting, Allow Everyone in Your Company to View This Video. If this option is deselected the video remains visible to the owner only.

Permissions allow the owner to share the ability to view or edit with groups they are a member of, by uploading to an existing channel or with individual people.

When the video is Shared with a group, channel, or select number of people they are automatically given the ability to view, however the ability to edit must be granted by raising the individual/group intended to Owner status.

Within the Privacy Settings, videos may be set as Public, Private, or Unlisted.

  • The Public setting allows anyone who can access YouTube to view the video.
  • The Private setting initially hides the video from everyone but the owner and allows the video to be shared with up to 50 select individuals via email addresses.
  • The Unlisted setting removes the video from any public search results/feeds however anyone with access to the link may view it.

Availability This application is available as a part of the Office 365 package which all University of Windsor faculty and staff have access to. This platform is available to the general public for use free of charge.
To learn more about how to use these features, please review the sections below Captioning in YouTube and Captioning in Microsoft Stream. Each section provides step by step instructions for users with images and/or animated GIFs for support. Both images and animated GIFs can be clicked on to examine at a higher resolution.
