ReVideeo

Web-based video editor with AI-powered auto-captions, multi-track timeline, transitions, and multi-format export.

Made with ❤️ in Poland for the European Union.

Render server required — For video export and AI-assisted editing, you need the separate render server: revideeo-render-server. The frontend app alone provides timeline editing, preview, and project management.

Render Server

Video export and AI-assisted editing features require the render server. It is maintained as a separate repository:

→ github.com/RevoProject/revideeo-render-server

The render server runs independently and is NOT part of this repository's browser bundle.

Quick Start

# Frontend
pnpm install
pnpm dev              # → http://localhost:5173

Deployment

pnpm build
vercel build --yes
vercel deploy --prebuilt --yes --prod

Third-Party Notice

This project does not include any Remotion code in its browser bundle. Remotion is used exclusively by the separate render server (revideeo-render-server), which maintains its own dependencies and license obligations.

See NOTICE for the full list of third-party dependencies and their licenses.

The @revideeo/player package (EUPL-1.2) provides an independent HTML5 preview renderer (NativePlayer) that does not depend on Remotion.
