Creating a screen recording of a second display with Apple’s QuickTime Player
One of the features of Apple’s QuickTime is that it allows a video recording to be made of your screen. This allows whatever you’re doing on the screen to be captured in a video and played back later.
To use QuickTime Player on OS X El Capitan to make a screen recording, use the procedure described below:
1. Launch QuickTime Player
2. In the File menu, select New Screen Recording.
3. In the Screen Recording window, click on the arrow drop-down menu and select the desired options.
4. Set up the conditions that you want to capture then click the Record button.
5. Select the desired option for recording either a portion of the screen, or the whole screen.
6. When you’re ready to stop recording, click the Stop button in the menubar.
Note: You can also press Command-Control-Escape on the keyboard to stop the recording.
By default, this procedure will work to record your Mac’s primary display but you can also use it to record an alternate display. For more details, see below the jump.
To create a screen recording of an alternate display, do the following:
1. Follow steps 1 – 4 of the procedure described above.
2. Move your mouse to the alternate display. You should see the recording options notification message appear on the alternate display.
3. Select the desired option for recording either a portion of the alternate display’s screen, or the whole screen.
4. When you’re ready to stop recording, locate and click on the Stop button in the menubar.
Note: Be aware that the Stop button may be in the menubar of the Mac’s primary display.
