You can quickly create a screencast at launch by first selecting sound and Webcam preferences, then hitting the red record button. The interface is fairly easy to understand right away with your media, transitions, animations, and effects on the left side, the work area (what they call the Canvas) on the right, and a video timeline on the bottom.
Camtasia for Mac makes it easy to create professional screencasts (capturing all actions on screen) for demonstration videos, instructional videos, and other screen-recording projects.
