Have you tried Camtasia or Captivate and found them too difficult to use? If so, you may wish to look at a free tool called Jing. Jing was created by the same company that makes Camtasia and SnagIt.
With Jing, you can create a “screencast” video showing anything on your computer. The Jing website describes the process this way, “Select a window or region and Jing will record a video of everything that appears in that area. Point to things with your mouse, scroll, flip through photos, click around in a website or application…Jing captures it all.”
You can add audio as well as capturing anything you would like to show on your computer. The screencasts are in Flash format, so viewers can see the screencast directly from Flash enabled browers.
The company recently released a new version called Jing Pro, which costs $14.95 a year. Jing Pro has the added advantage of uploading your screencasts directly to YouTube.
For more information, go to the Jing website. Jing is very easy to use, but the website also has tutorials available for getting started quickly.
If you try Jing, please comment here on your experiences. If you used Jing successfully to build a screencast, please post a link to it!
