Diffusion Studio

Diffusion Studio is a professional AI video editor built for both agents and humans, offered as a free and open-source product under the MPL 2.0 license. Everything runs locally in the browser, on a macOS desktop app, or through the dapi CLI, and the company's tagline is turning your agent into a professional video editor because every edit is written to a real codebase that coding agents can read, write and render. The interface is a rethink of video editing around modern design tools: you start on an infinite canvas where scenes are arranged spatially, then sequence them on a multi-track timeline, with everything staying connected so you can organize and iterate without losing visual context. Editing features include precise property control for timing, position, scale and layout from a single inspector; built-in visual effects such as Lumetri Color and Motion Blur; audio mixing with effects like EQ and denoiser; and motion design through bezier curves, spring easing and presets.

The AI side is equally central. A generation panel supports prompts with reference images and model settings for creating video, images, audio, speech and sound effects, and credits are consumed when models run to understand footage, transcribe it or generate media. Coding agents work through dapi, activated from the macOS app, together with official skills; Claude Code, Codex, Cursor, Copilot and Gemini CLI can analyze footage, make edits, create and animate scenes, build motion graphics, generate media, transcribe, localize, add captions and export, and everything they create stays fully editable by humans, with iteration in both directions. Performance is a selling point: sub-120ms canvas response, pan, zoom and scrubbing, and 4K playback and export with no proxies and no waiting, while 75,000-plus creators are cited as users. For teams, one project can hold entire productions, and because compositions are TSX, reusable components can be versioned in GitHub as shared infrastructure. The business model is credit-based: the editor, exports and agent workflows are free, and paid plans only add credits for AI model actions such as generation, footage analysis and transcription.
