Screencast-o-matic is a versatile Java-based web application used to create screencasts on Windows, Mac, and Linux operating systems. It captures screen and webcam video and saves it or posts it online on YouTube or the program's website. The system is easy to use and offers great high-definition recording.
It is possible to drag the recording frame and adjust its size to the appropriate recording area before recording. If you have a built-in camera, you can include video of yourself or something else in a “picture-in-picture” manner. It is also possible to add text files for captions. Videos can be saved in MP4, AVI, or FLV formats and then uploaded to Screencast-o-matic’s web space or YouTube.
Screencasts are very useful for demonstrating software use and other computer functions, presentation of lectures or short lessons, or providing rich feedback on students’ work.
Tools for Screencasting
A screencast is a movie of your computer screen that is often used to demonstrate how specific features of a software are used. Good screencast videos are short in length, they have audio - either as voice narration or in the form of background music - and they may also include some sort of notes or text transcripts to aid the viewers.
In the Screencast Tutorial page you can find a list of several freeware screen recorders, like Screencast-O-Matic, CamStudio, Wink, ScreenR and more.
