MasterSelects
A browser-based video editor for video, audio, motion graphics, and 3D. Build a multitrack edit, connect effects in a node graph, and use the in-app AI agent to work on the timeline. Editing and rendering run locally with React, TypeScript, WebGPU, and WebCodecs.

Build effects from connected nodes with live previews. Explore the Node Workspace.
What you can make
| Workspace | Highlights | | --- | --- | | Video | Multitrack editing, nested compositions, proxies, multicam, speed changes, and Premiere Pro sequence import. | | Nodes & effects | Editable image, color, geometry, and 3D graphs with typed connections, live previews, reusable groups, and animated controls. | | Audio | Waveforms, mixing, recording, effects, stem separation, beat-based editing, and a score editor. | | Motion | Text, shapes, captions, keyframes, masks, tracking, and rigged stick figures. | | 3D | Models, lights, cameras, Gaussian splats, particle simulations, woven curves, and optional path tracing. | | AI | Timeline editing through the in-app agent, plus image and video generation in AI Studio. |
Explore the feature guide, Node Workspace, Weave, Flock, and AI Studio. The 3D Scan workspace reconstructs scenes from photos or video and can show a training splat directly on the timeline.
Try it
Open masterselects.com, import a clip, and drag it onto the timeline. Press Space to play, C to cut, and Ctrl/Cmd+S to save. See the keyboard shortcuts.
Projects save continuously with branching history. Save waits for pending content and workspace changes to reach storage; named versions are separate from Save.
Use Chrome or Edge on desktop to get started. Hosted AI and media generation use external services and may require credits; local AI features may download models on first use. MasterSelects is under active development, so keep backups of important projects. See Linux GPU troubleshooting for platform-specific rendering constraints.
Run locally
Install the Node.js version in .node-version, then run:
git clone https://github.com/Sportinger/MasterSelects.git
cd MasterSelects
npm ci
npm run devOpen http://localhost:5173. Hosted login, credits, and AI services need the
full development stack and separate service configuration. Maintainers with the
private kernel checkout can use npm run dev:full; the hosted kernel is maintained
separately from this repository.
External coding agents can connect to the authenticated local editor with
npm run mcp. See AI bridge control for setup
and access boundaries. An optional Native Helper
provides desktop integrations, and an Android development app
packages the editor for mobile testing.
Contribute
I built MasterSelects because I wanted an editor I could shape around a project. When a tool is missing, a coding agent can add an effect, control, or workflow; you can try it in the same project and contribute it for others to use.
Focused pull requests, reproducible bug reports, and documentation improvements are welcome. For larger features, open an issue first. Read AGENTS.md for repository conventions and the feature guide for architecture and workflows.
