  3. Use the auto-captioning function or add a transcript you already have

  4. Review and edit the results for accuracy

  5. Share the appropriately captioned video

Captioning and transcription format

Captions and transcripts should include the following:
  • Punctuation
  • Who is speaking in brackets at the start of a new speaker
  • Ambient sound in brackets if applicable to media content
  • Vocal or emotional tone in brackets if applicable to media content
  • For vidoe, any on-screen text that is not read aloud in brackets
Learn more about bracket content format.


Captioning for a student requesting accommodations

If an instructor has a student in their course who is affiliated with the McBurney Disability Resource Center, McBurney will send instructors a faculty notification letter. McBurney will contact the instructor to discuss the accommodation process for McBurney providing sign language, live captioning (CART) services, or captioning pre-recorded media to the student. See McBurney Disability Resource Office departmental services for more information.


Pre-recorded (asynchronous)

The following tools can be used to add captions to videos using automatically generated machine captions which the instructor must then edit and review for accuracy and format.

Kaltura

Kaltura is a set of UW-Madison supported tools that allow you to pre-record your video (using Kaltura Capture) and then upload your video (to Kaltura MediaSpace) and add captions. 

  1. Install Kaltura Capture to record your video.

  2. Record your video/screen capture in Kaltura Capture using these best practices.

  3. Log in to Kaltura MediaSpace with your NetID and upload the video to Kaltura MediaSpace.

  4. Use the machine captioning function in Kaltura MediaSpace (“ordering machine captions”) to generate auto-captions. The results are approximately 75% accurate and are best recorded with a dedicated headset/microphone, and when there is a single speaker with no overlapping speech. 

  5. Review and edit the machine captioning results for accuracy and correct punctuation. In brackets state who is speaking at the start of a new speaker and indicate relevant ambient sound or emotional tone if applicable. Editing on average takes 3.5 times the duration of the video.

  6. Share the captioned video to Canvas using Kaltura MediaSpace or using Kaltura My Media within Canvas.

YouTube

A widely used and familiar video sharing site, YouTube typically integrates well with wherever you are sharing your video content. With your UW-Madison NetID, you already have an associated YouTube account and there is an automatic captioning feature.

  1. Login with your NetID or use the instructions on first time YouTube account setup

  2. Upload your video, or learn how to upload a video.

  3. Once your video is uploaded, you can add transcripts (if you have them), or use automatic captioning.

  4. Edit and review your captions for accuracy and correct punctuation. In brackets state who is speaking at the start of a new speaker and indicate relevant ambient sound or emotional tone if applicable. Editing on average takes 3.5 times the duration of the video.

  5. Publish your video

  6. Use the shareable link to add your Youtube video into Canvas or your preferred location to share content. 


Live web conferencing (synchronous)

Quick tip: a person involved in your live web conference has to caption for you. There is no automated option for captioning your video.

When conducting web conferences for course instruction or webinars, use Blackboard Collaborate Ultra or WebEx. For both services, select a web conference participant to be a “Live Captioner”. This person inputs captions while the session is in progress. See the following captioning guides for different services:

Blackboard Collaborate Ultra

WebEx
