Open-source huashu-motion turns Claude Code into a launch-film studio, 1.3k stars

AlchainHust · x · 2026-10-22

Developer Alchain remade the official Claude Duet launch film using Opus 5.5 plus huashu-motion, an open-source skill that renders every frame as code (HTML + GSAP) — and claims it turned out better than the original.

huashu-motion (1.3k GitHub stars, MIT) lets coding agents like Claude Code or Codex produce commercial-grade product films: say "make a 30s launch film for my product," and it reads your product, proposes three directions, writes the whole film and composes its own music, then opens a browser editor — click any frame, describe the change, and the agent fixes just that spot. Install: npx skills add alchaincyf/huashu-motion.
