NexGenVideo is an open source video editor for Mac. You and your agent can generate and edit videos together inside the timeline.
We built NexGenVideo from scratch with Swift. The north star is Premiere Pro, with our take on integrating AI into the workflow.
Generate videos and images with SOTA models like Seedance, Kling, Nano Banana Pro inside the timeline editor.
Connects your Claude/Codex/Cursor via MCP, or use the in-app agent to work on the same project together.
NexGenVideo ships with the editor, the generation providers, and a native generic
production engine (NexGenEngine, compiled into the app). Format packs add
structured, end-to-end workflows on top — the first is musicvideo (analysis →
treatment → storyboard → shotlist → render). Packs ship as signed .ngvpack
bundles outside the app. Activating a catalog pack downloads it on demand and binds
it to that project.
Learn how packs plug in — and how to add your own — in the format pack standard.
When the app is open, it exposes an MCP server at http://127.0.0.1:19789/mcp via HTTP. To connect:
Claude Code
claude mcp add --transport http nexgen http://127.0.0.1:19789/mcpCodex
codex mcp add nexgen --url http://127.0.0.1:19789/mcpCursor
The easiest way is go inside the app Help -> MCP Instructions -> Install in Cursor, or install manually by adding this to ~/.cursor/mcp.json:
{
"mcpServers": {
"nexgen": {
"type": "http",
"url": "http://127.0.0.1:19789/mcp"
}
}
}
Claude Desktop
We bundle a mcpb with the app that allows a one click install Desktop Extension on Claude Desktop. Go to Help -> MCP Instructions -> Install in Claude Desktop
Is NexGenVideo fully open source?
Yes — the whole app is open source: editor, MCP server, and agent chat. Generation runs through third-party providers (fal.ai, Runway, …) that you connect with your own API keys; only those providers' models are external.
Is it free?
The editor is free. You can download it with no login required, and use it as a video editor like CapCut or Adobe Premiere. You can also use the MCP server for free, and start experimenting using Claude Code/Desktop or Cursor to interact with your timeline editor.
Generative AI features use your own provider API keys — no account or login.
What platforms does it support?
macOS 26 (Tahoe) on Apple Silicon only.
