How we taught Chrome to export video

A HyperFrames team member explains how the framework renders HTML to deterministic video: Chrome's BeginFrame protocol controls timing, a seek(t) contract lets GSAP, React, WebGL and Lottie scrub to any frame, and parallel Chrome workers cut render time sharply. It argues coding agents such as Claude Code can write video as plain HTML and lists limits like WebGPU and font swaps.
