Camtasia Studio is software that allows the user to create professional looking screencasts. It has a lot more features than the other free and inexpensive versions, but the $299.00 price tag is a bit steep.

Some of the features include:

• The ability to record in numerous screen sizes and create videos in various file formats;
• Editing is similar to the features in Windows Movie Maker with some special options like Zoom-n-Pan, multiple audio tracks, transitions, and effects;
• There are a lot of presets that make it easy to produce videos for a blog, cd, dvd, HD, iPhone, iPod, the web, YouTube, and more;
• This software can be used to add audio to PowerPoint presentations and save as a video.  It can also capture live Powerpoint presentations.

There are numerous video tutorials easily accessible from withing the program to help explain how-to use most of the features.

One of the most useful editing features is the ability to zoom in closer on sections of the video to show things like a url being typed into a web page or to highlight areas that you want to emphasize.
