Camtasia Studio 3.1.2 | Mac OS X | 210 MB.

Excellent application to record videos and edit them later.
Camtasia for Mac is an excellent variant of the Camtasia Studio application developed exclusively for Macintosh to record and edit any recorded video from your desktop, either in full screen or what happens only in a particular space, like a webcam.

The program lets you record videos by specifying the sound source you want to record too and if you want the webcam is active or not.
After recording the video sequence we want, you can edit this by creating a powerful tool that includes all kinds of filters and video editing options.

After finishing the complete creation of the video it can be shared via iTunes, Screencast or YouTube, or exported as a video file format Flash 3G, AIFF, Quicktime, AU, AVI, Wave, MPEG-4 …

the essence remains the same. Camtasia for Mac records what you see on screen with absolute quality. Playback controls are simple and direct, just interfere with your work. And while you record the images, Camtasia for Mac gives you the opportunity to use iSight and micro, so your face and your explanations are integrated with the catch.
