Kaltura: Request captions for your Kaltura video


Kaltura is Oregon State University's video platform. Kaltura allows for captions to be added and played in a video. Captions can be added to a video by the video's owner or Disability Access Services at OSU, generated automatically, or ordered through a third party vendor.

If you are planning on sharing the video with students in Canvas, review how to edit the video and how to share the video in Canvas.

If you have a captioning request for your course through Disability Access Services, contact them directly to confirm all videos in your course have captions created in a way that meets legal accessibility requirements.

Oregon State University also has a contract with a captioning vendor, 3Play Media, to provide low cost accurate captions with a quick turnaround.

Furthermore, Kaltura allows for Automatic Speech Recognition (ASR) - also known as "machine captioning" - to be generated for your videos at no cost. Since these captions are automatically generated, they should not be considered to meet the definition of "accessible".

Requesting ASR ("machine") Captions

  1. Visit My Media in either Canvas or MediaSpace
  2. Click the video that you would like to have captioned
  3. Beneath the video, choose Caption & Enrich from the ACTIONS menu
  4. The "Service", "Source Media Language", and "Feature" options are set by default and cannot be changed
  5. Press the Submit button

Your captions should be ready within approximately 30 minutes of your order having been submitted.

Note: You can only request ASR captions for each video once. There is no cost to these captions.

Publishing Captions

After your captions are ready, it is advised that you review your captions and edit them, if necessary, to improve their accuracy.

Once you are satisfied with the accuracy of your captions, click the "Show On Player" button to add the captions to your video.

Note: Your ASR captions will not appear in your video until you have clicked the "Show On Player" button.

Consult the following tutorial for a video demonstrating these functions.
