Kaltura Drexel Streams -- Capture

Tagged with: audio capture


Great for voice-over PowerPoint presentations, Kaltura Capture lets you record anything you do on your computer screen as a video with audio. Kaltura Capture is an option within the Kaltura tool in Bb Learn, or within Drexel Streams. Once you stop the recording, you can easily upload to Bb Learn via the Kaltura tool.  Or to Drexel Streams, from which you can either upload to Bb Learn or share in other ways.

ExpressCapture is NOT the same thing as Kaltura Capture. You cannot screen record with ExpressCapture.

Advantage of Kaltura Capture?  The videos you make and upload to Kaltura or Drexel Streams and use in Bb Learn can allow viewers or students to make either the webcam video or the recorded screen video the larger or the more primary focus in the video at any time.

Quick Troubleshooting

Kaltura Capture has been a memory HOG in the past. The issue has been reported and may be resolved on some OS's or browsers. 

However, you may want to close non-essential applications before using Kaltura Capture.

And disable any ad blockers or privacy enhancing web browser plug-ins or add-ons for the Bb Learn and Drexel Streams websites, if you use any.

Also, open the applications you need for your recording before you start recording. Outlook, for example, in the past would't open while Kaltura Capture was in use. It had to be opened previously.

And if you run into persistent issues, try the other alternatives below for making screen recordings.

Low Volume/Hard-to-hear Audio?

If you are having trouble hearing a professor due to low audio, or bad audio, one possible work-around solution to try is to download/install the Chrome web browser and install the "Volume Master" extension from the Chrome Web Store at the link below.

We cannot find a similar link for Firefox as of yet. The above link has a good chance of working for other Chrome-based web browsers, such as the new Microsoft Edge and the Brave web browser, as well, which may be less resource intensive on your computer.
