Machine captioning is a service that uses artificial intelligence to create captions for the spoken audio in a media recording. Users can order automatic machine captioning for a single video or for multiple videos in My Media. These captions are around 80-85% accurate and can be edited by the user after the caption process is complete. Once the request is completed (usually 1-24 hours), the captions will automatically be present on the requested media.

  1. Access My Media, click the checkboxes of the desired Media (A). More than one can be selected.
  2. Click Actions (B), then click + Caption & Enrich (C).
  3. Click the Source Language (D) dropdown menu and choose the language spoken in the media recording.
  4. Click Submit (E). The captions will be added to the video(s) automatically (1-24 hours).
    Note: We highly advise these captions be edited for accuracy. See the Edit Captions section of this guide to learn how to edit captions once they are completed.

Professional captioning is more accurate and can be requested via the UAB Disability Support Services (DSS) request form. Caption requests on behalf of students requiring accommodations should be done through this method. DSS recommends all captioning requests be submitted one to two weeks in advance to allow adequate time to complete each request. If your media is in Kaltura, the captions will appear in the requested media once the process is complete.

If your media is in Kaltura, follow the instructions below to request professional captions.

  1. Open the request form by clicking DSS Captioning and Transcript Request Form on the DSS webpage.
  2. Click Login to request this service (A) and provide your BlazerID and Strong Password.
  3. Choose Closed Captions (B) or Caption File + Transcript from the Services Requested drop down menu.
  4. Type in the Canvas course (C) the media is placed in.
  5. Answer Yes/No (D) to indicate if the request is directly for a student needing accommodations currently enrolled in the course.
  6. Answer Yes (E) if the media is in Canvas and provide the title of the media as it shows in My Media (Kaltura).
  7. Click Submit (F). You will receive an email confirmation ticket and update to the progress of the request.
    Note: For information on how to get your video into Kaltura, see the Adding Media to My Media Guide.
