Providing captions and transcripts for videos on your website is a way of ensuring what?

Accessible Video Content

When including video and/or audio content on your site, you are required by law to ensure they meet WCAG 2.1 AA standards.  This means ensuring you are providing closed captions/subtitles and transcripts where required.

If your video has audio content, captions are required.  This is a requirement for both pre-recorded and live video content.

  • For pre-recorded videos, captions are required in WCAG at Level A.
  • For live videos, captions are required in WCAG at Level AA.

You need to include closed captions/subtitles on any video with spoken dialogue. Therefore, in any video when someone is talking, subtitles should display what is said.

What are closed captions?

Closed captions are a text version of the spoken part of a video. Captions are called 'closed' captions because they are hidden, until they are opened by the viewer from a menu to view.  It is the same as choosing to turn subtitles on when viewing a TV programme. On your website, the user can choose to turn captions on when viewing your video.

Adding Captions to a Mediasite Video

To add captions to a Mediasite video, the staff member needs to register for the Mediasite Learning and Teaching group.  Mediasite does not currently auto include captions without being registered.  You can find out how to register on the Mediasite information pages.

Adding Captions using Youtube

Youtube auto includes captions for videos you upload.  You can choose to either leave the auto captions as they are or edit the auto captions to make them more accurate.  It is recommended that you manually refine the auto captions. Youtube shows you how to add and edit captions using its online guidance.

Google Chrome Captions

One of the latest features in Google Chrome is that anyone can enable live captions on videos and audio played through the Chrome browser. Learn how to use live captions in Chrome

Live Captions in MS Teams

Accessible Audio Content

Audio content typically means a podcast you are including on your site. WCAG 2.1 regulations require all audio content published to the web to be supported by text equivalents. This means all audio podcasts require a transcript.

What is a transcript?

A transcript is a text based translation of the audio content of a video or podcast.  This should also include notes on who is speaking if there are multiple presenters. It can be presented either as an accompanying accessible pdf or form part of the text of the web page itself.

Advice on Podcasts

Please contact the Mediasite team for advice on how to create Podcasts using the Mediasite platform and how to create a transcript of your recording.

Captioning & Transcripts

Creating captions and transcripts for your videos is a simple but important step to ensure everyone has the opportunity to engage with your content and that you're complying with legally required digital accessibility guidelines.

Creating Accessible Videos

Every time you create a video to be shared with others, you will need to follow a few simple instructions to ensure that video is properly captioned. This will make your content more usable for all viewers, including people who:

  • Are trying to listen in a noisy environment.
  • Have hearing loss or impairments.
  • Prefer to read captions due to the way they learn and absorb content.
  • Are non-native speakers.
  • Are having trouble understanding the speaker for any reason.

Always provide captions. 

You must caption any and all videos you plan to ask others to watch or otherwise engage with, such as those created for:

  • Websites, Apps and Digital Tools of Any Kind
  • Social Media Posts
  • Emails
  • Course and Classroom Materials 
Include non-speech sounds in your captions.

Be sure to caption noises too! Music, applause, laughter, nature sounds, sound effects, etc. all communicate information in your video. Those who can’t hear the video won’t know about those sounds unless you tell them in your captions by putting these sounds in brackets as they play. For example: [Laughter] or [Applause].  

Add Captions More Quickly

If you need to add captions to a video after it's been recorded, we recommend uploading the video to Microsoft Stream using your Teams account to add auto-captions to your video. You will still need to review the captions and make corrections, but Teams' captioning accuracy is some of the very best for auto-captioning software.

Using Microsoft Stream for Captions and Transcripts

Audio Files

If you are sharing an audio-only file like a podcast or another  audio recording, you should provide a transcript of the audio via an accessible document or on a web page. The link to your transcript should be readily available from the screen where you are sharing the audio file.

Music

If you need to share an audio file that is all or mostly music, your accessibility liaison will be able to help determine the best way to communicate that content in an accessible way.
