Smooth functioning: Camtasia provides a lot of nice features in a fluid interface that makes creating screen capture videos and processing them a breeze. You can set the program to record either the screen or a PowerPoint presentation. You can also choose to record your entire screen or only a portion of it that you preset before recording begins. The recordings, themselves, are clear and crisp, providing you with an excellent framework on which to put all the finishing touches and effects you want.
CamStudio is a compact little program with some nice features tucked away to maximize its allure. Installation is a breeze. However, when you launch CamStudio, a private product upgrade is offered that has not been verified by SourceForge. You’ll have to decide if you want to take a chance on CamStudio’s private upgrade or not. Yet, once you launch CamStudio, you’ll find several helpful features to make your screen recording journey quite enjoyable. For example, controls to record an entire screen or a portion of it, sound options, and the ability to add comments to videos and screen captures. CamStudio and its codec are released under GPL license.
