A screencast is a recording of what’s happening on your computer screen. It’s very similar to sharing your screen during a video call. However, while screen sharing occurs live and in real time, a screencast is recorded for others to view later. Or, put differently, a screencast is like a moving screenshot.
When making a screencast, everything that is visible on your screen will be recorded. This might include active programs, open documents, and even the movement of your mouse.
So what is the purpose of recording your screen? The most common use for screencasts are how-to videos. By recording your screen, you can show someone how to use a program or perform certain actions without having to sit next to them. Screencasts are also frequently used to create webinars and tutorials.
