Today a friend of mine asked me "What is a screencast?". I get this question often from fellow developers and finally decided to create a blog entry I can reference going forward to answer the question.
Screencast concept is best defined by Wikipedia entry:
Screencast is a digital recording of computer screen output, also known as a video screen capture, 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.
Just as a screenshot is a picture of a user's screen, a screencast is essentially a movie of what a user sees on their monitor.
Now that we have the formal definition, let me provide some very good examples of .NET technology related screencasts:
- dnrTV: Quality .NET screencasts on various topics related to .NET technology
- The Moth - Channel9 Screencasts: A collection of screencasts created by Microsoft MVP Daniel Moth
- How Do I Video Series: A very large collection of videos brought to you by Microsoft on .NET technologies.
In my own words screencasts are an excellent way to learn how to program or use various tools in a visual environment. If you Google this term along with a topic of interest the odds are you will find some content.
Enjoy!
