Camtasia is one of those products that you see a lot of people using, but for some reason takes a long time to justify purchasing. If you don’t know what Camtasia is, it’s a program that lets you create screen recordings, optionally along with voice, and then edit them to create great presentations or training videos. Screencasts can then be published in a number of formats, including Flash. The best part about the software is that it’s just SO easy to use!
Ease of use really is the key here. The software is quick and easy to use, so you can create a screencast in little more time than it would take to demonstrate something to one person, and then save that screencast to a reference library that you can draw upon in the future.
