How do I record lectures using Kaltura Capture?

Recorded lectures work best when they are short.  According to one study, student attention begins to drop off after the six-minute mark in a recorded lecture.  By rule, TED talks don't last longer than 18 minutes.  Pre-recorded lectures can be used to provide initial exposure to difficult concepts, since students can watch the videos multiple times.  You can also use recorded lectures for simpler concepts that don't require extensive in-class discussion.  At Bucknell, we have an easy-to-use tool called Kaltura Capture that allows you to record your lecture slides along with your voice/face as you deliver the lecture.  To use Kaltura Capture, you need only a Webcam, microphone, and Internet browser.  You don't need any pre-installed software.  Here are instructions on how to record a lecture using Kaltura Capture:


Using your Internet browser, go to:


Click the Login button in the upper right hand corner. (If you are already logged in to one of our single-sign-on systems, as in Bmail or myBucknell, you will pass straight through to Mediaspace.  Otherwise, you will be prompted to log in)


Click on the + Add New menu button, and within the menu that drops down, click on Kaltura Capture.


Install the desktop plugin to your computer.

After the installation is complete, you will need to re-select the Kaltura Capture option from the + Add New menu in Mediaspace.

After the plugin is installed, you should see the options on the right for the sources you can include in your recording.

Kaltura Recording Options


Determine which input sources you’ll want to record. (For a narrated lecture, you'll most likely want the options shown here: screen, camera, and audio.)  Screen allows full desktop or window selection options, and audio includes options from either the internal microphone OR an external mic.  (External microphones are recommended for improved audio quality.)

Start Recording


A recording monitor will appear near the lower right corner of your screen as you record.  If you are recording a lecture presentation (and capturing your computer screen), you'll want to switch to your lecture slides (PowerPoint, Google sides, etc.) and page through those slides as you record your comments.

When you Save a recording without uploading it, the Management window opens with the Edit tab and displays the options to Upload or delete your media.
