Renders HTML, CSS, and JavaScript animations into deterministic MP4 video frames.
Renders HTML, CSS, and JavaScript animations into deterministic MP4 video frames.
html-animation-to-mp4 captures HTML/CSS/JS animations in a headless browser and encodes the frames with ffmpeg. Claude Design .dc.html bundles can expose their own frame-seek hook, while --virtual freezes clocks and advances ordinary canvas, WebGL, or CSS animation frame by frame. It supports multiple aspect ratios and frame rates; capture is silent by default, and Playwright, Node, and ffmpeg are required for the CLI.
