Captioning Services

The Center for Disability & Access is pleased to offer captioning services of course content for approved CDA registered students free of charge. Contact your CDA advisor to find out if you qualify.

Closed captioning (CC)

Closed captioning is the process of displaying text on a visual display (TV, monitor, etc.) to provide additional or interpretive information. Typically the text is a transcription of the audio portion of a program as it occurs, sometimes including descriptions of non-speech elements.

  • The term "closed" (versus "open") indicates that the captions are not visible until activated by the viewer using a menu or remote.
    • Note: On Canvas and most online video players, closed-captions are turned on by clicking on a "CC" menu on the video player and then selecting the language of captions from the available list.
  • Captions are stored in a captions file (we use .srt) which also includes a time-code for syncing the captions with the video. Many video players will play a captions file with your video.

Open captions

If a video has open captions, the captions are permanently displayed on the video and cannot be turned off.

Captions, Transcripts and Audio Description (WebAIM info article)


Captioning requests should be made at least 10 days in advance of when the video is needed.

Please make requests for captioning services to:

If requesting for a University department, please include:

  • Title(s) of the videos
  • Department name and contact name
  • Whether you would like open or closed captions
  • Video file or info on how we can access the video (web link, Canvas info, cloud service)
  • Date the captioned video will be used

For University departments, captioning services from the Center for Disability & Access are provided for a fee. Please contact us for more information.

Audio/Video Transcription Services

We will also accept requests for transcripts of audio and video material following the same guidelines as above.

Audio Description Services

Audio description services for videos is available. Turnaround time for production is a minimum of 7 business days. Please contact us for more information.



Delivery of captioned videos or caption files will depend on the project. Most are delivered by one of the following:

  • Kaltura video server update (for videos posted through Canvas/Kaltura tools)
  • Amara web captioning service (For YouTube/Vimeo videos)
  • MediaSpace
  • Digital file (typically for open captions)


Using YouTube/vimeo Videos on Canvas

We are not able to add captions directly to videos linked by URL on a Canvas page. For these videos we will add a "(CC)" link on your Canvas page under the linked video that will redirect students to the website or the University's Mediaspace site which will host the video with captions.

If you embed YouTube videos in your Canvas course using the "Embed Kaltura Media" tool in the page's HTML Editor (pictured below), we can add captions directly on these videos. You do not need to be the YouTube/Vimeo channel owner to do this. This method will be more convenient for students using captions, and requires minimal effort for the content creator. Please contact us if you need any support using this method.

If you are the owner of the YouTube/Vimeo account where the video is posted, you can add caption files that we have produced for you to your videos, create your own captions, or update the existing Automatic Captions (for YouTube). We are happy to show you how this is done, or use the help articles linked below. 


Audio Embedded PowerPoint Presentations

Your audio embedded PowerPoint presentation can be more easily be captioned if it is converted to a video. These videos can also be embedded in to your course content in Canvas. To convert your presentation to a video on Windows, open your PowerPoint file and go to the File menu, select Exports, then Create a Video. Adjust any settings and click Create Video. An .mp4 file will be created of your presentation. We are happy to do this conversion for you if you have a student in your course with a captions accommodation.

Kaltura Capture

PowerPoint presentations or other presentations can easily be recorded along with audio or video using the University's Kaltura Capture tool in Canvas or Mediaspace. This is a great screen capture tool. Check TLT's help article on using Kaltura Capture and more on their Canvas: Media knowledge article


Thank you! This service is a crucial piece to our student’s success and has a positive impact for many other students as well.
