TechSmith released a free image capture / screen recorder tool yesterday called Jing. I focused on the video recording features because we have SnagIt here at work. Jing is very easy to use. I installed it, configured it (setting up Screencast), and created a video in about 10 minutes. Jing is cool because it allows you to record your entire screen, an entire application or objects within applications. After recording one click sends your video up to Screencast and even puts the URL to your video in your clipboard!
We will probably use this tool for training.
