CamStudio

CamStudio is able to record all screen and audio activity on your computer and create industry-standard AVI video files and using its built-in SWF Producer can turn those AVIs into bandwidth-friendly Streaming Flash videos (SWFs).

CamStudio can be really useful if you want to share your explanations or if you want to show someone how to do something by using the computer.

Creating demonstration videos for any software program is really easy, you only have to click on record and then do what you have to do,when finished, click stop and the file will be saved according to the parameters you set.

Finally, choose the output quality and the video-size.
