A new tool called Agentcut is bridging the gap between code generation and visual media production by allowing developers to watch Claude Code or Codex edit videos in real time. Released on October 23, 2026, the open-source project leverages Remotion, a React-based video creation framework, to translate natural language prompts into editable timeline scenes. Unlike traditional AI video generators that operate as black boxes, Agentcut exposes the underlying React components, enabling users to inspect and modify every layer of the production process directly within their local environment.

Local-First Architecture and Agent Integration

Agentcut operates entirely on the user's machine, requiring Node.js LTS version 20.10 or newer. The architecture is notable for its lack of a backend server; all API keys, project files, and agent processing remain local. The tool functions as a harness that interfaces with existing coding agents, specifically supporting both Claude Code and Codex. Users can switch between these models within the chat interface, maintaining access to the same toolsets and skills regardless of the underlying LLM. This design choice ensures privacy and reduces latency, as the agent writes real Remotion scenes and places library components while the preview rebuilds live in the browser.

Granular Control Over Motion Graphics and Assets

The system comes equipped with 49 open-source components, including kinetic titles, lower thirds, word-by-word captions, and stat counters. These assets are not static templates but dynamic React components that the agent places on the timeline based on user prompts. For instance, a user can request a "kinetic Bauhaus poster" or an "AI chat input," and the agent will assemble these using specific motion graphics and music syncs. The interface includes an inspector panel that allows for manual tweaks to any prop, such as changing the value of a stat counter or adjusting the timing of a transition, providing a hybrid workflow between AI generation and manual editing.

Key Takeaways

  • Agentcut uses Remotion to convert natural language prompts into editable React video scenes.
  • The tool supports both Claude Code and Codex, allowing users to switch models mid-workflow.
  • It operates locally with no backend, keeping API keys and project files on the user's machine.
  • The project includes 49 open-source components under the MIT license, ranging from kinetic titles to stat counters.
  • Users can export MP4 files directly in the browser in both 16:9 and 9:16 aspect ratios.

The Bottom Line

Agentcut represents a significant shift toward transparent, code-based AI video editing, moving away from opaque generation models to inspectable React components. By harnessing existing coding agents like Claude Code, it demonstrates that LLMs can effectively manage complex timeline logic when given the right structural framework. This tool challenges the notion that AI video editing requires proprietary cloud infrastructure, proving that local, open-source stacks can handle real-time, high-fidelity media production.
