Cut, grade, caption, generate — on a real multi-track timeline. Or just tell the agent what you want and watch it edit.

_{That palm tree? Generated inside the editor, straight onto the timeline.}

What it does

🎬 Real timeline editing	Multi-track, ripple & razor tools, linked A/V, sync-locked tracks, keyframes on opacity/position/scale/crop/volume, snapping, frame-accurate trims
🎨 Color & effects	20 GPU effects: color wheels, curves & hue curves with histogram, LUTs (.cube), chroma key, blur/grain/glow, 16 blend modes
✨ AI generation	Video, image, audio & TTS via fal.ai — Veo, Kling, Seedance, nano-banana and more. Your key, your cost control, results land in the library
🤖 The agent	A chat that edits your timeline: cuts, layouts, color, captions — 40+ tools over the same undo stack you use. Any model via OpenRouter
💬 Captions & transcription	On-device Whisper transcription (free, no key), word-level editing, 11 animated caption presets, remove filler words by text
🔍 Visual search	Search your footage by what's in it — on-device SigLIP embeddings, no cloud
🔌 MCP server	Point Claude (or any MCP client) at your project — 43 tools to edit it from the outside
📤 Pro interop	Export FCPXML (DaVinci Resolve / Final Cut), XMEML (Premiere), SRT/VTT subtitles, MP4 render

Run it

• Web — frontstage.studio: the full editor in your browser, no account, no keys needed for editing

• Windows — download the installer (unsigned: SmartScreen will warn — "More info → Run anyway")

• macOS / Linux — use the web editor (no install, full functionality)

• From source (Node 18+, pnpm 10):

  pnpm install
  pnpm -F @frontstage/desktop dev     # desktop app
  pnpm -F @frontstage/web dev         # web app

Your keys, your data

AI features are strictly bring-your-own-key: fal.ai for generation, OpenRouter for the agent. Keys live in your OS keychain (desktop) or your browser (web) — never on anyone's server. Transcription and visual search run entirely on your machine, free. Zero telemetry.

Let Claude edit your project (MCP)

The desktop app ships an MCP server (Settings → Agent → enable). Add it to Claude Code / Claude Desktop:

{
  "mcpServers": {
    "frontstage": {
      "type": "http",
      "url": "http://127.0.0.1:19789/mcp",
      "headers": { "Authorization": "Bearer <token from Settings>" }
    }
  }
}

Then: "split the interview at every silence and add captions" — and watch your timeline change. 43 tools: editing, color, generation, transcription, export.
