A screencast is a digital recording of a computer screen's output, typically accompanied by audio narration, used to demonstrate software, create tutorials, or deliver online presentations. Screencasts are the foundational format for software tutorial channels, online course content, and tech review videos. Tools like Camtasia, Loom, OBS, and QuickTime enable screencast recording. Unlike screen sharing (which is live), a screencast is a recorded artifact that can be edited and distributed asynchronously. Screencasts are a high-value content format because they provide step-by-step visual instruction.
