When you record your desktop, Screencastify captures everything on your entire screen or in a specified application. Here's a quick walkthrough for:
Start a desktop recording
- Click the extension icon
to open up the Recording Control Panel - Select the Desktop
option
- To narrate over a recording with your microphone, enable "Microphone"
and choose your audio device. The soundbar next to the microphone icon 
will light up if it is successfully detecting sound. If it's not, click here to troubleshoot audio issues. - To embed your webcam into your recording, enable "Embed Webcam"
and select your camera - To capture the audio coming from your computer, click "Show more options" and enable "System Audio."
NOTE: If you are using a Mac, System Audio is not available due to operating system limitations. However, you can still record your tab audio to capture the audio emanating from a specific tab.
- To narrate over a recording with your microphone, enable "Microphone"
- Click "RECORD"
Next, a window will pop up asking if you'd like to record your entire desktop or a specific application:
- If you choose a specific application, Screencastify will only capture that application window.
After you've made your selection, click "Share" 
.
You'll hear a countdown and then your recording will begin.🎉
NOTE: When Screencastify is recording, a red dotwill appear in the extension's icon.
End a desktop recording
When you're finished recording, click the Screencastify extension icon and click the stop button 
. You'll then be taken to the Video Details Page, where you can edit and share your recording.
