Perfect Presentations Every Time

Camtasia Studio allows individuals with no multimedia or programming expertise to create on-demand demonstrations, presentations, and screencasts to communicate in an effective, engaging and visually informative way to share knowledge and ideas about technology.
Camtasia Studio automatically records exactly what a user sees on a computer screen, what they say, and how they interact with any application or Web site on a Windows-based desktop. Users can then edit and share the recordings online or via fixed media in all popular streaming media formats, including Flash (SWF).
