Kaltura - Editing Captions in a Video

This article describes how to edit captions in a Kaltura video .

Instructions:

Captions are, for the most part, machine generated in Kaltura. This process is handled by Automatic Speech Recognition (ASR) technology, and is about 80% accurate. The remaining errors can be corrected by hand. This process is not immediate, and captions will take some time to appear. If you rip the video from a DVD or download from another location, captions may already be available.

The overall process of creating a captioned video consists of:

1. Uploading to Kaltura
2. Requesting captioning if necessary
3. Correcting/editing captions:

The Understanding Captions and Captioning Workflow outlines a variety of starting points for video and the steps to get those videos captioned.

This article guides you through the captioning options noted below.  Click on any of the links to navigate to the section you would like to learn more about.

Editing Captions within Kaltura

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

          

2. This will bring up your transcript and 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.
