HyperFrames review
HyperFrames is an open-source framework that turns HTML, CSS, media, and seekable animations into deterministic MP4 videos, built for AI coding agents.
TL;DR
HyperFrames is an open-source framework from HeyGen for rendering HTML compositions into MP4 video. It targets developers and AI coding agents such as Claude Code, Codex, and Cursor. Compositions are plain HTML with data attributes and need no build step or React, and the same input produces the same frames.

What HyperFrames does
- HyperFrames renders HTML, CSS, media, and seekable animations into deterministic MP4 videos.
- HyperFrames ships agent skills that teach coding agents to plan, write HTML, animate, add media, lint, preview, and render videos.
- HyperFrames supports GSAP, CSS, Lottie, Three.js, Anime.js, WAAPI, or a custom frame adapter for seekable animation.
- HyperFrames offers a catalog of about 450 ready-made blocks such as transitions, overlays, captions, charts, and maps, installed as editable source.
- HyperFrames can render locally, in Docker, or through a distributed AWS Lambda render stack.
- HyperFrames includes Studio, a browser surface for previewing and editing compositions, and an embeddable player web component.
- HyperFrames provides frame.md, which converts a web design system into a DESIGN.md superset an agent can compose video from.
How it works
HyperFrames defines a video as HTML with data attributes for timing and tracks. You preview it in the browser with live reload. To render, the engine seeks each frame in headless Chrome via Puppeteer and encodes the result with FFmpeg, so the same input gives the same video. You can drive it with the CLI or from coding agents through installed skills or plugins.
How to install and start using HyperFrames
Agent skills (core set)
npx hyperframes skills updateStandalone skills picker
npx skills add heygen-com/hyperframesRequirements
- Node.js 22 or later
- FFmpeg
First steps
- Scaffold a project with `npx hyperframes init my-video`, then `cd my-video`.
- Run `npx hyperframes preview` to preview the composition in the browser with live reload.
- Run `npx hyperframes render` to render the composition to MP4.
- Or ask your agent, using `/hyperframes`, to create a short product intro with a title, background video, and music.
Who HyperFrames is for
- Developers using Claude Code, Codex, Cursor, or Gemini CLI to generate videos from prompts.
- Automated content pipelines and CI that need deterministic, repeatable video renders.
- Product launch videos, PR walkthroughs, data visualizations, and social videos with captions.
- Teams that want to author video in plain HTML rather than React components.
Limitations to know
- HyperFrames requires Node.js 22+ and FFmpeg installed locally.
- HyperFrames Studio is marked as available but still evolving.
- HyperFrames animations must be seekable, through a supported adapter or a custom frame adapter.
- HyperFrames skills installed via `skills add` can lag the main branch by hours.
