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". Co-editors can also request machine captions, but they must check the box next to the video on the main "My Media" page and click Actions in the top right corner instead of navigating to the individual video.

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. Select your options
    1. The "Service" is set to "Machine" by default and cannot be changed
    2. For "Source Media Language", you can select either "English" or "Spanish"
    3. For "Feature", you can select "Captions" or "Alignment" (click here to learn more about transcript alignment)
  5. Press the Submit button

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

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

Review and Edit Your Captions

After your captions are automatically generated, it is prudent to review them and make corrections as necessary.

To edit your captions:

  1. Visit My Media in either Canvas or MediaSpace
  2. Click the pencil icon that corresponds to your video in order to edit that video's information
  3. Choose the Captions tab
  4. Click the Edit Captions button and the captions editor will open
  5. To edit the timestamp of each line, click the desired timestamp to modify the time. The editor will highlight any overlapping time.
  6. To search, enter your text in the "Search in captions" box.
  7. To find and replace text:
    1. Enter your search term in the "Search in captions" box
    2. Enter your replacement term in the "Replace with" box
    3. Click Replace
  8. To add a speaker ID:
    1. Select the rows you want a speaker added to
    2. Enter your speaker ID in the "Add speaker to selected items" box
    3. Click Add
  9. When you are finished making edits, click Save

To modify the label for your captions:

  1. Visit My Media in either Canvas or MediaSpace
  2. Click the Edit button for the desired media
  3. Click the Captions tab
  4. In the Actions section, click the pencil to edit the label
  5. In the pop-up window, modify the label
  6. Click Save

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

Publishing Captions

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

Whether you review your captions for accuracy or not, automatically generated captions are NOT published by default. After machine captions are generated, you must then publish them.

To publish your captions:

  1. Visit My Media in either Canvas or MediaSpace
  2. Click the Edit button for the desired media
  3. Click the Captions tab
  4. In the Actions section, click the "Show On Player" button as demonstrated in the animation below.

Consult the following tutorial for a video demonstrating these functions.
