Record your screen with audio, even with captions or in-picture webcam, using CamStudio
CamStudio records screen and audio activity on your computer and creates AVI video files. Using its built-in SWF Producer can turn those AVIs into streaming Flash videos (SWFs)
You can use CamStudio to create demonstration videos, tutorials for school or college class, etc.
CamStudio can also add anti-aliased (no jagged edges) screen captions to your recordings, or even a webcam movie of yourself “picture-in-picture” over your desktop.
You can choose to use custom cursors, to record the whole screen or just a section of it and to reduce or increase the quality of the recording (for emailing to people, for instance).
