HyperFrames Turns HTML and GSAP Animations Into Deterministic MP4 Files
HyperFrames is an open-source TypeScript framework developed by HeyGen that converts HTML, CSS, and GSAP animations into frame-perfect MP4 video files via a command-line interface. The tool chains Puppeteer for headless browser rendering, GSAP for deterministic animation timing, and FFmpeg for video encoding, ensuring the same HTML input always produces identical output. Unlike conventional video tools designed for human designers, HyperFrames treats video as a build artifact, making it suitable for AI agents that require structured, reproducible outputs. It integrates with AI workflows through an MCP server and a skills.sh distribution, allowing coding agents to invoke video rendering as a native capability. The project has gained significant traction on GitHub, accumulating 42,000 stars and ranking among the top trending TypeScript repositories.
