And the best part about QuickTime 10 is… Screen recording. Long a task that required 3rd party products, recording events from your screen in Mac OS X is now built in with QuickTime 10. Simply open up QuickTime, click on File and then select New Screen Recording. From there, a screen will appear with a red button to start recording. Don’t worry as that screen will not appear in your recording. Instead you will be able to use the Command-Control-Escape keystroke to stop recording.
At the Screen Recording screen you will also be able to perform a few settings changes. Here, use the disclosure triangle to switch between microphones, change quality and even change the default location that recorded movies are saved to. The third party applications that can do screen recording in Mac OS X are still a bit more mature, but if you need to do basic screen recording, QuickTime itself now seems poised to become the de-facto standard.
