Limelight
What is Screencast?
A screencast is a video recording of what happens on a computer screen, usually paired with voice narration, used to teach or demonstrate software.
A screencast is a digital recording of computer screen output, frequently accompanied by audio narration. The term combines "screen" and "broadcast." People make screencasts to explain how an app works, walk through a workflow, deliver an online lecture, or document a process for teammates. The result is a video file that viewers can watch and replay at their own pace.
A screencast differs from a static screenshot because it captures motion over time: clicks, scrolling, typing, and transitions. It differs from a webcam video because the primary subject is the screen itself, not a person. Tools such as QuickTime, OBS, ScreenFlow, Camtasia, and Screen Studio create screencasts. Quality screencasts often add visual aids so viewers can follow the cursor and understand which keys were pressed.
Limelight is not a screencast recorder. It is a macOS menu-bar overlay that runs on top of whatever recorder you already use. While your recorder captures the screen, Limelight adds a cursor spotlight, an on-screen keystroke display, and freehand drawing directly on the screen, so those visual aids appear in the finished screencast. It records and uploads nothing itself; it simply makes the screen clearer for your audience.

FAQ
- Does Limelight record screencasts?
- No. Limelight is an overlay only. You use your own recorder, such as QuickTime or OBS, and run Limelight on top to add a cursor spotlight, keystroke display, and drawing.
- How does Limelight improve a screencast?
- It makes the cursor easy to follow, shows which keyboard shortcuts you press, and lets you draw on screen, so viewers can track every step in the recorded video.
