How to use QuickTime to record video and audio playing on your mac...
Thanks to QuickTime’s handy capturing capabilities, recording video playing on your mac is actually very simple.
First you’ll need to make sure you have the latest version of QuickTime on your system. I’m running version 10.1.
If you have an earlier version, run a manual software update in OS X, or head on over to the QuickTime website to get the latest update.
Then simply open QuickTime
Click on ‘File‘ in top menu bar
Click ‘New Screen Recording‘
Select ‘Built-in Input/Internal Mic‘ from the drop down menu
Now click ‘Record‘
You will then be given the option to record the whole screen, or use the mouse to select the area of the screen you wish to capture.
This setting records audio and video in one .mov file. Note, that the audio is captured from the in-built microphone, which is great if you’re filming a tutorial, but not so great if you’re looking for high quality audio recording too.
To record high quality audio playing on your mac, you can use QuickTime in conjunction with a little app called Soundflower. This software basically routes any audio playing on your mac through your recording software, for a lossless way of capturing audio when you cannot digital extract the audio from a source.
