This software can also capture and record almost anything that can be played or displayed on the computer screen. The program saves the video on your hard drive as avi, wmv or many other file types.

Now a full retail version of Camtasia Studio 5 costs $300 but you can have Camtasia for free.
The only catch is that this offer is available for Camtasia Studio 3. Download the demo of Camtasia Studio 3 here and then request a registration key from Techsmith here to convert that demo into a full licensed version.
Though you may miss some of the new features like Auto Pan and Zoom, Camtasia Studio 3 will still solve most of your screencasting problems – also includes quizzing, titles, PIP and support for recording PPT presentations.
Once you download a free copy of Camtasia Studio 3, it can be upgraded to Camtasia 5 edition at half the standard cost. Thanks Paul and labnol.org.
