SmoothScroll Studio Capture

One browser extension: keyframe the scroll, export an MP4. Rendered entirely on your own machine, every animation intact.

Turn your website into a movie. One browser extension: keyframe the scroll, export an MP4. Rendered entirely on your own machine, every animation intact. The page is stepped, not filmed. Screen recorders film the page in real time, one busy CPU and the scroll stutters. The studio takes over the page clock and advances it by exactly one frame per capture, then screenshots only once the compositor has painted. A slow machine means a slower export, never a worse video. Three moves from tab to MP4. • Pick a tab — every open tab shows up in the studio. Choose one and an output size, from 720p up to 4K. • Set the curve — drop keyframes at scroll positions, then tune duration, easing and strength for each segment between them. • Export — frames are captured through the DevTools protocol and encoded with WebCodecs, on your graphics hardware wherever it can. The file lands in your downloads. Your session comes along. Localhost, staging and pages you are signed into all record like any other tab. Nothing leaves your computer. The extension makes no network requests of its own. Capture, encode and save all happen on your machine, which is why it works on internal tools without a compliance conversation first.
