Miguel ÁngelandClaude Opus 4.6 e2061694f2 fix(producer): pass entryFile to renderStream handler + add debug logging
The renderStream handler was missing entryFile in createRenderJob,
causing all composition renders to fall back to index.html.

Also adds logging for staticDuration and entryFile to help diagnose
duration detection issues.

Hyperframes

Node.js

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.
