Auto Zoom Screen Recording — Free in Chrome

A raw screen recording is functional and forgettable: a tiny cursor wandering a cramped frame, the viewer squinting to follow what you clicked. The recordings that hold attention zoom in when something matters, glide the cursor instead of jittering it, and sit the capture on a clean background instead of butting it against the window edges. Screen Studio made that look famous, then made it a paid macOS app.

SuperchargeCapture brings the same three effects into a free Chrome extension, rendered on your own machine. One caveat up front, because it shapes how you record: the auto-zoom and cursor effects apply to tab recordings.

Auto-Zoom That Follows Your Clicks

The signature effect is automatic. During a tab recording, the extension captures pointer positions and the moments you click. The video gently zooms toward each click and eases back out afterward, so the viewer’s eye lands exactly where you acted, without you placing a single keyframe. Clicks that come close together merge into one sustained zoom instead of pumping in and out, and the camera is already gliding in as the click lands rather than reacting after it.

This is the difference between a recording someone tolerates and one they actually watch. The motion is gentle, the framing follows intent, and nothing about it requires editing skill.

Every Zoom Is Editable After Recording

The automatic pass is a starting point, not a verdict. Each zoom the extension creates lands as a block on its own lane of the editor timeline, under the clip track, and every property of it is yours to change:

• Retime it — drag a selected block’s in and out points to move where the zoom starts and ends.
• Change its strength — a Level slider runs from a subtle 1.2× to a tight 4×.
• Re-aim it — drag the focal dot on the preview and the zoom drives toward that spot instead of the click position. A re-aimed zoom stays pinned where you put it.
• Delete it — one click removes a zoom the automatic pass shouldn’t have made.
• Add your own — drop a zoom at the playhead, or use Draw zoom to drag a box on the preview. The box becomes a zoom that fills the view with exactly the region you drew, its strength derived from the box size.

So the honest description is no longer “the zoom is decided at record time.” The clicks give you a competent first draft; the timeline gives you the final cut. These editing tools read the same pointer data the automatic pass does, so they too are part of the tab-recording package.

The Tab-Recording Caveat, Stated Plainly

Auto-zoom and the cursor effects depend on captured pointer samples, and those samples are recorded when you record a tab via the “This tab” source. Window and screen recordings capture no pointer data at all, so the zoom-on-click and cursor polish don’t apply to those captures. If the polished, zoomed look is what you’re after, record the tab. We’d rather you know this before you record than discover it at export, so it’s worth repeating: the auto-zoom magic is a tab-recording feature.

Cursor Polish and Padded Backgrounds

Two more effects round out the Screen Studio look:

Cursor polish replaces the twitchy real-cursor path with a smoothed track and adds a subtle ripple on each click, so taps read clearly. Padded background frames the whole capture on a gradient backdrop with rounded corners and a shadow, with the Dusk (amber) and Graphite presets joined by solid colours, custom gradients, and your own wallpaper image — or switch it off for a raw, unframed export. The background framing works on any capture, so even a window or screen recording gets the clean, presentation-ready frame.

Rendered Locally, Not in a Cloud

Every one of these effects is applied during export, on your device, to the footage you already captured. There’s no cloud render queue and no quality loss from a server round-trip. The source stays sharp and the polished file is produced right on your machine. That’s the whole point of a local-first tool: Screen-Studio-grade output without sending your screen to anyone.

When you’re done, export to WebM, to MP4 where the browser supports MP4 recording (WebM always works), or to a scaled GIF (up to 120 seconds) for a quick loop.

Privacy

The recording and all of its polish stay on your device. Pointer samples used for auto-zoom are captured only during your recording and only to render the effect locally; they aren’t transmitted anywhere. No account, no telemetry, nothing injected into pages until you start a capture.
