There are lots of tools to use for screen captures, but one of the most useful and intuitive applications to use for screen cast video capture is Jing by Techsmith. It’s available for Windows and Mac.
There’s a free version and also a Jing Pro version for $14.95 per year. (Note: Jing Pro is retired; use Snagit instead.) Screen shots and videos can be easily saved and shared on your favorite social media site; that’s the beauty of Jing. Your Jing account is connected to a Screencast.com account with 2 GB storage for easily storing your videos.
Once you sign up for your account, and install Jing, you can begin recording immediately. If you want to record audio, be sure to plug in your mic first. You can also set your Preferences by clicking on the gears on the sun logo before your first recording.
