The process of clicking pictures from the desktop and making a movie out of it is automated with the use of ScreenCam. The tool will click pictures from the desktop and then convert all the snapshots into a movie. It also allows you to delete the pictures that you do not want in the output.
Furthermore, the application lets you customize the pictures in terms of size, part of screen etc. You can also review the pictures before deleting and the undo and redo features lets you try out various options. The humble user-interface is only a pleasant addition to all the present features.
