For various reasons, you may need to record what is happening on your screen. Perhaps you want to record a video tutorial or are trying to create your own machinima video. Here's how you can do it.
Steps
Method 1 of 2: Using QuickTime (preinstalled)

Method 2 of 2: Using Jing (Free Download)

Step 1. Find out what Jing is
Jing is a free image grabber that comes in both Mac and PC versions. In terms of its functions, it is very similar to QuickTime, with a number of additional features. We'll take a closer look at Jing's screen capture capabilities.

Step 2. Download Jing
You can do this by going to TechSmith.com

Step 3. Install Jing
Jing's setup wizard works on a move-and-paste basis. Just move the application to the Applications folder, then launch it.

Step 4. Start Jing
Once launched, Jing will appear as an image of the sun at the top right of the screen. You can install it in the menu bar as well. Hovering the mouse cursor over the image of the sun will bring up a menu on the screen.
- The illustration shows the Capture function. There is also a function Historywhich keeps a history of all your entries, and the button Morewith which you can access the settings.

- Post the result to Screencast.com. This option will allow you to share videos or screenshots you take with anyone on a service that, as you might have guessed, is called Screencast. You can send the resulting link to anyone you want.
