HyperCam captures the action from your Windows screen and 
       saves it as a standard, easily edited, AVI (Audio-Video 
       Interleaved) movie file. This format can be played under 
       Windows, as well as the Internet, unlike other programs that 
       use proprietary formats that may need special viewers and be 
       difficult, if not impossible, to edit. HyperCam lets you 
       define the precise area of the screen you want to capture, 
       unlike MS Camcorder and others that record the entire screen
       
       These files can be useful as teaching tools, to demonstrate 
       software, as a start for animation, and for many other uses. 
       This easy to learn, flexible system will have you making your 
       first screen movie in no time at all
