OpenMontage

OpenMontage: Open-source video production system that uses AI agents to create and edit video, images, audio, animation and 3D.

OpenMontage is an open-source, agentic video production system that turns your AI coding assistant into a full video production studio. It manages the entire production lifecycle through eight stages and one gate, covering brief, research, script, scene plan, narration, music, compose, and render. Users can bring their own material or start from an idea, directing a complete production or specific elements using AI agents. The software runs locally on your machine with integration support for tools like Claude Code, ChatGPT Codex, and OpenCode. It supports multiple output formats including 16:9, 1:1, and 9:16 with a complete provenance record for every asset.
