Hyperframes is an open-source framework that turns HTML into deterministic, frame-by-frame rendered video — so you can define a video the same way you build a web page.

​
See It in Action

Here is a video defined entirely as HTML: 
<div id="root" data-composition-id="demo"
     data-start="0" data-width="1920" data-height="1080">

  <video id="clip-1" data-start="0" data-duration="5"
         data-track-index="0" src="intro.mp4" muted playsinline></video>

  <h1 id="title" class="clip"
      data-start="1" data-duration="4" data-track-index="1"
      style="font-size: 72px; color: white;">
    Welcome to Hyperframes
  </h1>

  <audio id="bg-music" data-start="0" data-duration="5"
         data-track-index="2" data-volume="0.5" src="music.wav"></audio>
</div>
Run npx hyperframes render --output demo.mp4 and this produces an MP4 with deterministic, frame-by-frame capture. Same input, identical output, every time. No timeline editor. No proprietary format. Just HTML.

Why Hyperframes?

You already know the stack. Compositions are HTML files with data attributes. Animations use GSAP, Lottie, CSS, or any runtime that can seek to a given frame. There is no custom DSL, no proprietary component system, and no React requirement. If you can build a web page, you can build a video.
Hyperframes was designed from the ground up for AI agent integration. Compositions are plain HTML that any LLM can generate. The CLI is non-interactive by default — flag-driven with plain text output — so agents can scaffold, render, and lint without interactive prompts. Add --human-friendly for the interactive terminal UI. See CLI for details.

​
How It Works

1

Write HTML

Define your video as an HTML document. Each element gets data attributes for timing (data-start, data-duration) and layout (data-track-index). Add animations with GSAP, Lottie, CSS transitions, or any seekable runtime via the Frame Adapter pattern.
2

Preview in the browser

Run npx hyperframes preview to open a live preview in your browser. Edit your HTML and see changes instantly — no build step, no compilation.
3

Render to MP4

Run npx hyperframes render --output output.mp4 to produce a final video. The engine seeks each frame in headless Chrome, captures it with beginFrame, and pipes the result through FFmpeg. Run locally or in Docker for fully reproducible output.
