I made a 4K film of the James Webb launch and unfolding. No frame of it came from an AI video or image model. Every frame is computed by code running in a browser. Built with Claude Opus 5.5. Sound on 🔊 How it works The film is a website that plays itself. Each chapter is a React component, a function of time. Remotion opens it in headless Chrome, steps through one frame at a time, and encodes all 2,700 frames at 3840×2160 to MP4. 3D three.js/WebGL: PBR materials, shadows, bloom, depth of field. The telescope is NASA's own JWST model. Opus rigged every mechanism (pallets, tower, mid-booms, 5 sunshield layers, the secondary mirror tripod, both mirror wings) to go from folded to deployed. Effects Liftoff smoke is thousands of lit, depth-sorted particles whose positions are computed from time, so every render is identical. Earth is a custom shader with 8K day, night and cloud maps and an atmosphere that thins with altitude. The HUD and titles are plain HTML, CSS and SVG. Music…
