Jing is a great tool for capturing a screencast. I have been using it for a few weeks now and it allows me to create video of what I am doing on my computer screen. I am now creating video tutorials for my customers.
Jing is a perfect solution for tutorials that run under 5 minutes. Jing is a free tool but they do offer a more robust paid version
