Kaltura will automatically caption videos that are uploaded, recorded using Kaltura Capture or Express Capture, or imported from a Zoom cloud recording. While the quality of these automatic captions is generally good, there will always be editing required to ensure that the captions meet WCAG 2.1 accessibility guidelines. Usually, editing of spelling, capitalization, and punctuation is all that is required but in some cases the machine-generated captions will have critical errors in content that will need to be corrected.

There are several ways to get to the Kaltura Caption Editor, but most efficient way is to:

  1. Log in to Kaltura
  2. Go to My Media
  3. Find the video in the listing
  4. Click the Edit button (icon looks like a pencil)

  5. Click the Captions link to view the captions that are available for your video.  For each set of captions you will find options under the Actions column including: set as default on the player, edit the name that you want to appear on the player (ex. English), delete the caption file, download the caption file, or display/hide from player. Choose which caption set(s) you want to appear on the player , which set should be the default, and how you would like them labelled.Kaltura video details page showing the location of the Captions button and the Edit Captions buttons
