How to Record Vertical 9:16 Video for Social on Mac

The core problem is aspect ratio. Your Mac display is landscape, roughly 16:9, while Reels, TikTok, and Shorts want a tall 9:16 frame. Apple's built-in Shift-Command-5 toolbar can only record what is on screen in its native shape, so a straight capture leaves you with a wide video that you would have to crop and reframe by hand in another app afterward. You can record a selected portion to get closer to a tall region, but you are still fighting the geometry and end up with awkward letterboxing or a cramped slice of the interface.

Limelight handles this directly. It is a native macOS screen recorder that, alongside standard mp4, exports to a vertical 9:16 clip, so you capture your Mac normally and get a social-ready tall video out the other side. Because it auto-zooms into every click and smooths the cursor into clean motion, the important action is pushed into the center of the frame where a vertical crop keeps it visible. The clean padded background fills the tall canvas attractively instead of leaving empty bars, so your clip looks designed for the format rather than jammed into it.

Vertical clips also live or die on pacing and clarity, since viewers scroll fast. Limelight bakes on-screen keystrokes, a cursor spotlight, and freehand annotations into the video, so even in a small phone-sized frame a viewer can see exactly what you pressed. In the built-in editor you can trim to the strongest few seconds, cut anything slow, ripple-delete dead time, speed up setup steps, and adjust the zoom so the payoff is unmistakable. That combination of automatic emphasis and quick editing is what turns a plain screen capture into a scroll-stopping short.

When it looks right, export the 9:16 clip and post it, or export a standard mp4 too if you want a horizontal version for other platforms. Everything records locally and fully offline, so unreleased features stay private until you publish. Limelight is free to start with the cursor spotlight, and Pro is $2.99/month or a $34 one-time lifetime license. Keep in mind Limelight does not record audio, captions, or a webcam yet, so if your short needs a voiceover, record it with Shift-Command-5 or QuickTime and add it, along with any captions, in your social editor.
