How to Record Audio, Video, and Screens in QuickTime Player
Most folks don’t think of QuickTime Player as a recording application because Apple provides applications (such as Photo Booth and iMovie) that have long been the recording tools of choice in the Mac universe. However, you can indeed record audio, video, and your Mac’s screen display with QuickTime Player, as long as your Mac is equipped with the proper hardware (a microphone or a line-in device for audio and an iSight or a FaceTime HD camera or an external video camera for video).
When you’re ready to record, launch QuickTime Player, click File and choose New Movie Recording, New Audio Recording, or New Screen Recording. Click the down arrow icon next to the Record button to display a menu where you can choose your input sources and recording quality.
When all the settings are correct, the process itself is a one-click operation: Click the big red button to start and stop recording. QuickTime displays both the recording time and the approximate hard drive space used so far.
When you’ve finished recording, QuickTime Player even provides a Share icon at the right of the toolbar, allowing you to immediately share your new masterpiece with your friends via social media, Messages, or Apple Mail. ‘Nuff said.
