Lecture capture is the process of creating video and audio content for any standard, hybrid, or online course. By recording your voice and computer screen, it allows you to digitally record your classroom lecture or presentation.

You can record PowerPoint presentations, website articles, videos, etc. either in the classroom or at home and then share them online with your students.

*Equipment Needed:

  1. USB Microphone
  2. Webcam (optional)

*It is recommended that you acquire your own microphone. In the meantime, if you do not have a USB microphone or webcam, you can request an equipment loan by filling out the Audio/Video Equipment Online Request Form and contacting:
