Hyperframes

Write HTML. Render video. Built for agents.

Hyperframes is an open-source video rendering framework that lets you create, preview, and render HTML-based video compositions — with first-class support for AI agents via MCP.

Why Hyperframes?

• HTML-native — AI agents already speak HTML. No React required.
• Frame Adapter pattern — bring your own animation runtime (GSAP, Lottie, CSS, Three.js).
• Deterministic rendering — same input = identical output. Built for automated pipelines.
• AI-first design — not a bolted-on afterthought.

Quick Start

npx hyperframes init my-video
cd my-video
npx hyperframes dev      # preview in browser
npx hyperframes render   # render to MP4

Requirements: Node.js >= 22, FFmpeg

How It Works

Define your video as HTML with data attributes:

<div id="stage" data-composition-id="my-video" data-start="0" data-width="1920" data-height="1080">
  <video
    id="clip-1"
    data-start="0"
    data-duration="5"
    data-track="0"
    src="intro.mp4"
    muted
    playsinline
  ></video>
  <img id="overlay" data-start="2" data-duration="3" data-track="1" src="logo.png" />
  <audio
    id="bg-music"
    data-start="0"
    data-duration="9"
    data-track="2"
    data-volume="0.5"
    src="music.wav"
  ></audio>
</div>

Preview instantly in the browser. Render to MP4 locally. Let AI agents compose videos using tools they already understand.
