How to Record Narrated Slides and a Demo on Mac

Both Keynote and PowerPoint can record narration inside a slideshow, and that built-in path is fine when you never leave the deck. The moment you want to switch from slides to a real app demo, though, in-app slide recorders get clumsy, because they are not built to capture other windows well. That is where a screen recorder earns its keep: run your slides in presenter mode, then Command-Tab to your app for the live portion, and record the whole thing as one continuous screen capture so slides and demo flow together seamlessly.

Record that screen capture with Limelight for a polished result. It records locally and offline, sits everything on a clean padded background, and smooths the cursor throughout. During the demo section, Limelight automatically zooms into every click so the audience follows the live product, and it bakes on-screen keystrokes into the video so any shortcuts you use are visible. This keeps the demo portion just as clear as your designed slides, instead of dropping into a flat, hard-to-follow screen share the second you leave Keynote or PowerPoint.

Now the honest part, which matters a lot here because narration is the point. Limelight does not record audio yet, no microphone and no system audio, and it does not generate captions. So record the visual pass, slides plus demo, silently in Limelight, then record your narration separately with QuickTime or Shift-Command-5 and lay the voiceover over the video in an editor. Recording narration to a finished visual actually helps, since you can pace your words to what is on screen and re-record a single line without redoing the whole deck.

Assemble and refine in an editor, using Limelight's built-in tools first. Trim the setup, ripple-delete stumbles, speed up any slow transitions, and adjust the zoom so the demo lands on the right control, then bring the clip into your editor and sync the voiceover, nudging slide changes to match your narration. Export mp4 for a webinar replay, a course, or a proposal, or vertical 9:16 for a short teaser. Limelight is free to start with the cursor spotlight, and Pro is $2.99 per month or a $34 one-time lifetime license.
