OpenMontage

About

An open-source agentic video production system that takes a brief plus your own materials and runs a nine-stage pipeline — research, script, scene plan, approval gate, narration, music, compose, render — to produce a finished, editable video. Costs are estimated and held at an explicit approval gate before any paid generation happens, and composition and rendering run locally with a provenance report covering source, licence, and model for each asset. It runs as a plugin inside existing coding agents including Claude Code, ChatGPT Codex, and OpenCode, as well as its own Studio app.
