CamStudio: Free screencasting software
CamStudio download page (link)
Ever wonder how to “record” your efforts online, from Line Rider to Google Earth, and export them into a video file you can upload and share?
CamStudio can do that.
CamStudio is a flexible, powerful, and (most importantly) free piece of software that can record what you do on-screen as an .avi file.
Screen recordings — also known as screencasts — are especially useful in web tutorials and presentations. Â They could benefit you in creating presentations and movies for our class.
You can use CamStudio video files as-is, or edit them into larger presentations.
