Making a Panopto recording
At its simplest, you can just use the microphone on your laptop or iMac to record your voice and the computer screen. If your computer doesn’t have a microphone, or the built-in sound isn’t good enough, try using a USB headset or your earbuds (with microphone).
Here’s an example of a Panopto lecture recording made by Professor Laura Listenberger of the Chemistry Department, using the document camera in a Regents classroom. Use the arrow on the lower right to expand the recording into its own window in order to see the doc cam window.
