Kaltura: Remove Automatic Captions

When videos are uploaded to Kaltura in Moodle and Canvas, they are automatically captioned by a service called Cielo24. This article describes how media owners and co-editors can remove the automatic caption and associated files from a specific video in Kaltura.

Removing Automatic Captions

1. Open a browser and navigate to Moodle or Canvas.
2. Navigate to your media:
   • Canvas: Click on one of your courses and select My Media in the course menu.
     
   • If the link is not shown, the course's owner can add My Media to the Canvas course menu.
   • Moodle: Click on your name in the top right of the browser window and select My Kaltura Media from the drop-down menu.
     
3. Locate the video from which you would like to remove automatic captions.
4. Click Edit (the pencil icon) located to the right of the video.
5. Click the Captions tab under the video.
6. Click the X next to the English caption to delete it.
   
7. Click Delete in the popup box that appears.
   

Removing Associated Files

• Note: When videos uploaded to Kaltura are automatically captioned, additional files are created for use in the Interactive Transcript Viewer. This feature is not yet available at the University of Minnesota. However, when you remove caption files, it is a good idea to remove the associated Interactive Transcript Viewer files as well. This way, if/when the transcript viewer becomes available, it will create a more predictable experience for viewers.

1. Open a browser and navigate to Moodle or Canvas.
2. Navigate to your media:
   • Canvas: Click on one of your courses and select My Media in the course menu.
     
     If the link is not shown, the course's owner can add My Media to the Canvas course menu.
   • Moodle: Click on your name in the top right of the browser window and select My Kaltura Media from the drop-down menu.
     
3. Find the video you want to remove automatic captions from.
4. Click Edit (the pencil icon) located to the right of the video.
   
5. Click Attachments under the video.
6. Click the X next to both transcript_en.txt and c24Trans_en.json.
   
7. Click Delete in the popup box that appears.
