A screencast is a digital
recording of
computer screen output, often containing audio
narration.
Although the term screencast dates from 2004, products such as
Lotus ScreenCam were used as early as 1993. Early products produced large
files and had limited editing features. More recent products support more
compact file formats such as
Macromedia Flash and have more sophisticated editing features allowing
changes in sequence, mouse movement, and audio. Screencasts are useful for demonstrating features of both simple and complicated software. Creating a screencast helps software developers show off their work. It is a useful skill for ordinary software users as well, to help report bugs (the movie takes the place of potentially unclear written explanations) or to show others how a given task is accomplished in a specific software environment. Screencasts are excellent tools for learning how to use computers, and several podcasts have started to teach computer users how to use software through screencasts. The term was coined by columnist Jon Udell in 2004 in an article [1] describing the benefits of using the technique as a way to show other users applications he found interesting. Since then, the term has gained widespread use, and the use of screencasts has itself become more popular. |
