Screen Studio turns a plain Mac screen recording into a smooth, zoomed, polished demo with almost no editing, and founders adore it

Every startup needs product videos, and almost nobody on a small team has time to keyframe zooms in a video editor. Screen Studio's big idea is that the recorder should do that part for you. It watches where you click and type, then zooms in on the action, glides the cursor smoothly between moves and adds a touch of motion blur. The result looks like it was cut by someone who does this for a living.

Adam Pietrasiak shared the first version on Hacker News in December 2022, describing a four-month build aimed at making promo-quality videos easy. He grew it in public on X, and it became a familiar sight in launch videos and feature announcements across the startup world. The site lists people at Shopify, Netflix, Google and plenty of others among its users.

Where it shines

The magic is in the defaults. Automatic zooms can be tweaked by hand, but often they are already right. You can switch between full camera, split screen, camera overlay and screen-only layouts inside one recording, and export the same take as a widescreen video for your site, a square clip for LinkedIn and a vertical one for short-form feeds.

It has grown into a proper editor too. You can trim by editing the transcript like a document, strip filler words, add styled captions generated on your Mac, clean up your voice on-device and blur anything sensitive. Need to show a mobile app? Plug in an iPhone or iPad and record it directly.

The best way to start

Record the one flow you explain most often, like onboarding or your headline feature, and post it to your launch page and socials in each aspect ratio. Then use the shareable link feature for quick walkthroughs to customers and teammates. Mac users only, and very happy ones.

Hit record, click around, and walk away with a demo that looks like it had an editor.
