Why Make a Screencast

Screencast is a digital recording of computer screens, full screens or screen regions and usually comes with an audio narration to describe the on-screen actions. The term screencast dates back to 2004 with an interesting story.

In 2004, a columnist Jon Udell invited readers of his blog to propose names for the emerging genre. In all the suggested terms, Udell selected screencast, which was proposed by both Joseph McDonald and Deeje Cooley. His "Heavy metal umlaut" screencast is a well-known example - which explains how Wikipedia works. http://weblog.infoworld.com/udell/gems/umlaut.html
Since then, the term screen has be known by more people and the use of screencasts has itself become more popular. Currently the new trend of screencast is documentary filmmaking of software-based social networking services like Wikipedia, del.icio.us. or digg.

Guide Lines of making a screencast

Know what you want to present
First and foremost, You’ll need to have an idea about what you’ll present, and you’ll need to figure out which platform to use. Knowing your purposes of making a screecast is the first step.

Make it real
Always make a screencast real and substantial. For example, if it is for software demonstration or a network monitor, then work with the software or live network.
Of course , for reasons of logistics or security, this isn’t always possible. But the more real you can make it, the better.

Interactivity is important
Interactivity engages viewers through the demo. If your screecast is just screen by screen, your viewers will leave soon. You can and should record narration or insert background music to the screencast. Usually, some screencasting tools like DemoCreator enable you to add some visual aids to the captured screens like callouts, shapes, annotation buttons and animated images. Note that when a screencast is interactive it will engage the viewers in a conversation that steers it into unexpected areas.
