What is OpenMontage?
OpenMontage is the world's first open-source, agentic video production system. It gives you 12 production pipelines, 52 tools and over 500 agent skills — all working together inside Claude Code to produce complete, professional videos from a single text prompt.
You describe what you want. The system researches, scripts, sources footage, generates narration, edits a timeline and renders a finished MP4. Without you touching a camera, editing timeline or paying per video.
Imagine hiring a master chef who works for free, never takes a day off, never asks for a raise and can cook any dish you describe — as long as you provide the ingredients.
You are the restaurant owner. OpenMontage is your master chef. Claude Code is the kitchen manager passing your orders to the chef. Your prompt is the menu order. The API keys are your ingredients. The finished MP4 is the meal served hot.
Once the kitchen is set up — you cook unlimited meals. The chef never burns out. Never sends an invoice per dish.

This is the part that surprises most people. According to OpenMontage's own published examples — real production costs are dramatically lower than any monthly subscription:
OpenMontage ships with a built-in $10 budget cap per generation run — so the agent estimates cost before executing and stops automatically if the cap is reached. No surprise bills. Ever.
This guide uses Claude Code — included with Claude Pro. But OpenMontage also works with other AI coding assistants. The repository ships dedicated configuration files for each one:
The Challenge
OpenMontage is powerful. It is also technical. The official documentation assumes you already know what a PATH variable is, why FFmpeg matters and how to handle a command line without panicking.
Most people who try to install it on Windows hit errors like these within the first twenty minutes:
Why This Guide
I am not a developer. I installed OpenMontage on Windows and documented every single step as I went — including every error, every confusing screen and every moment where I had to stop and figure out what to do next.
The errors that will catch you are already caught and fixed inside these pages. The confusing decisions are already made and explained. The exact clicks, the exact commands and the exact fixes are all here.
Most installation guides are written by developers who have forgotten what it feels like to not know what a PATH variable is. This guide is written from inside the beginner experience — while it was still fresh.
