I got tired of janky screen recordings — so I built Scrollcast

Every landing page needs a video. A preview for a case study, a clip for stories, a demo of a template for sale. And every time it's the same story: you record the scroll with the system recorder — and out comes jank. The scroll stutters, frames drop, and instead of "wow, so smooth" you get something you're embarrassed to show.

Smoothness is half a designer's job. So I built a tool that guarantees it.

Scrollcast is a browser extension. Open a site → one button → get a smooth scroll video. Not a screen recording, but a synthetic scroll, computed section by section: even acceleration, soft braking, pauses where the eye should linger.

A clean plate, not a finished clip

Scrollcast's main decision — it hands you a clean plate: no browser chrome, no background, no shadows. Just a smooth scroll of the site on a clean frame.

Why? Because styling is your territory. The device mockup, background, shadows, effects — you'll make those in Figma or After Effects exactly the way you see them. Scrollcast doesn't impose a style — it gives you a perfectly smooth base to do anything with.

What's inside

• —Auto-scenario. The scan finds the page's sections and builds the scroll itself — showing every block, losing nothing.
• —Pace, not budget. You pick the character of the motion — Calm, Natural, Dynamic — and the duration adapts. No sections silently disappearing.
• —Position fine-tuning. Didn't land the frame on the right spot in a section? Click, drag on the page, lock it in.
• —Desktop and mobile frames. 1440/1280/1024 and iPhone/Android — pick a size, hit record.
• —Clean MP4 (H.264), 2× on Retina.

Built openly and tested

Scrollcast was built iteratively and honestly — with an automated bench that runs the scan, scenario and recording itself, catching regressions. Every frame, every bit of smoothness — measured, not promised.

Launching soon

Right now Scrollcast is in active development — final details before launch on the Chrome Web Store. If you build landings on Framer / Webflow and you're also sick of janky previews — stay tuned, it's coming soon.
