kinetograph.

A blazingly fast programmatic video engine, made for agents.

Kinetograph makes videos from code, without a browser. You (or an agent) write a video in TypeScript with Remotion's API, or as a plain HTML page. Node runs the code, and a Rust GPU compositor draws every frame: CSS, SVG, Canvas 2D, WebGL shaders, 3D and Web Audio. Existing Remotion projects render as they are, and so do HyperFrames projects. The film above is one TypeScript project in examples/launch.

Kinetograph is in beta (version 0.3.0). APIs can still change between versions.

Install

You need Node.js 22 or newer. The prebuilt package covers macOS on Apple Silicon, Linux x64 and Windows x64, and installs in about a minute with nothing else to set up:

npm install kinetograph
npx kinetograph doctor

Building from source is only for working on the engine, or for a platform with no prebuilt package. It needs Rust and the FFmpeg libraries and takes 15 to 30 minutes: see Installation: From source.

Install with a coding agent

Paste this into Claude Code, Codex or another coding agent:

Set up Kinetograph (https://github.com/0xS4N4TG/kinetograph) for me by following its AGENTS.md:
https://github.com/0xS4N4TG/kinetograph/blob/main/AGENTS.md
Ask me first whether I want the prebuilt package (recommended) or a build from source,
and ask before installing anything system-wide or installing the Kinetograph agent skills.

Make a video

Start a project in an empty folder:

npx kinetograph init          # TSX, Remotion-style
npx kinetograph init --html   # or an HTML / HyperFrames page
npm install

init makes src/ for code (or html/ for a page), public/ for images, fonts, audio and video, and out/ for everything Kinetograph writes. It also writes a starter title card. Render it:

npx kinetograph render src/index.tsx      # writes out/renders/Main.mp4
npx kinetograph render html/index.html    # for an HTML project

How it works

Node runs your project and a Rust addon draws each frame on the GPU. The Engine page walks through the six steps.
