Add Onscreen Text to a Kaltura Video


This tutorial provides instructions on how to add onscreen text to a Kaltura video. This is done by adding a URL hotspot, but not actually adding the URL itself - only the text.

Any Kaltura media owner can add a hotspot to a video they own. This applies to all UCSD instructors, students, and staff with active directory credentials.

Critical Concepts

A hotspot is a textbox layered on top of the video that allow for several actions if a viewer clicks on it while watching:

  2. Ensure that the "URL" radio button is selected.
  3. Leave the "link to" field blank.
  4. Click Done. (If you want to explore the "Advanced Settings," read below.) You should now see a little yellow box has appeared above the timeline at the bottom of the Video Editor, and above the timeline.
  1. Position the hotspot within the player window by dragging and dropping it where you see fit. You can also enlarge the box, though this won't change the font size.
  1. Play the video or use the scrubber in the timeline to find the time in the video when you no longer want the hotspot to be onscreen for viewers. Drag the right side of the yellow box that's above the timeline to that desired endpoint.

Advanced Settings

You have additional configuration options for your hotspots that you can access by clicking "advanced settings" when an existing hotspot is selected in the Video Editor. In addition to being able to change the text and link or timecode (depending on the type of hotspot), you have control over the look and feel.
