Editing Captions within Kaltura

  • We'll begin with editing within the Kaltura system. Select "Edit Captions".

Make your changes keeping in mind that each section of your transcript requires time code to keep the captions associated with the video in the proper place. Click on the text you want to edit and make your changes, the text box will become editable once you click on it. You can also search within your captions, replace text, and add a speaker. These changes will be reflected in the transcript as well.
