Anyone interested in producing professional-looking movies and demos from the computer screen needs some quality screencasting software, and TechSmith's Camtasia definitely fits the bill. This app strikes the perfect balance between powerful tools and ease of use.
Considering the relatively minor boost in version number, Camtasia offers quite a few feature updates. The program now includes the capability to record system audio, as well as automatically resize windows during recording. Plus, you get the option to "smartfocus" on key frames and add closed captions to your presentation. Additonally, the app offers speech-to-text with a voice training feature; auto output to more formats, such as the iPad; and the capability to overlay text and search within Flash video.
