What Does Screencast Mean?

A screencast is a digital video recording of a user’s screen or desktop complete with real-time or post-edited narration. It is often done as a video tutorial to allow viewers to follow exactly what the tutor/narrator is doing. It is related to the term screenshot, but whereas a screenshot is just a single image of the content of a computer screen, a screencast is a full video recording.

Techopedia Explains Screencast
