Frequently asked
What is screencasting?
Screencasting is the practice of recording your screen as a video, usually with narration, so you can teach, demonstrate, or explain something visually instead of in writing.
The video you produce is called a screencast. While a one-off screen recording is often just a quick capture, screencasting tends to describe the ongoing activity and format, the kind used for tutorials, online courses, software walkthroughs, and onboarding clips. The narration and on-screen actions together guide the viewer through each step.
Any screen recorder can produce a screencast. Sirvez is one free option: it's a Chrome extension that records a tab, your desktop, or your webcam, adds microphone narration and cursor highlighting, and lets you trim and annotate before you share, so a finished tutorial comes together in one place.
