What is region capture?

Region capture lets you draw or define a rectangular area and record just that part of your screen, leaving everything outside it out of the footage. Instead of capturing an entire display — with its menu bar, dock, and unrelated windows — you isolate exactly the content that matters, such as a single app window, a browser tab, or one panel of an interface. This produces a tighter, more focused recording and avoids the need to crop away large empty margins later in an editor.

The feature is valuable for both clarity and privacy. By framing only the relevant region, you keep the viewer's attention on the subject and avoid distracting clutter, and you also prevent private notifications, tabs, or desktop icons from sneaking into the recording. Selected-area capture is common for focused tutorials, bug reports, and demos of a specific tool, where the surrounding desktop adds nothing. Choosing a region that matches your target aspect ratio up front also saves reframing work when you export for a particular platform.

Limelight records your Mac's screen and then enhances it with auto-zoom, cursor smoothing, on-screen keystrokes, and a clean padded background, producing a focused result whether you're capturing a window or a portion of the display. Its built-in editor lets you trim, cut, speed up, and zoom to tighten the final video further, and it exports in 16:9 or vertical 9:16. The emphasis throughout is on keeping only the important content sharp and front and center.
