Remove the Split and Delete toolbar buttons which had many edge cases (style capture, media offset, depth counting, DOMParser + regex hybrid). Replace with an Edit button that: 1. Opens a modal with time range selection (start/end sliders) 2. Shows all elements that overlap the selected range 3. Provides a prompt textarea for describing the desired change 4. "Copy to Agent" button copies structured context to clipboard The AI agent handles the actual HTML mutation — which is what it's good at. This eliminates ~300 lines of fragile split/delete code. Removed: splitElement, deleteElement, applyBakedStyles, styleCapture.ts Kept: parseStyleString, mergeStyleIntoTag, findElementBlock (useful utilities)
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.
