How to do screen recording in Windows and OS X

This is something you all should know how to do cause it comes in handy.

For OS X - Fire up Quicktime Player, follow these instructions.

This will only record the video unless you install Soundflower, which is a nice free program that will let you record the audio output. After setting up Soundflower, make sure you tell Quicktime to capture audio from Soundflower instead of your microphone if you want to record your speaker output.

For Windows - I use OpenBroadcaster Software, which is what many gamers use to stream games via Twitch.tv. It lets you record your entire monitor or select a window to record. It will also record your audio output AND your microphone output simultaneously.

How cool is that?
