// summary

OpenMontage is an open-source, agentic system that transforms AI coding assistants into comprehensive video production studios. It automates the entire creative workflow, including research, scripting, asset generation, editing, and final composition. The platform supports both AI-generated visuals and real-footage documentary montages using a variety of free and premium tools.

// technical analysis

OpenMontage is an agentic video production system designed to transform AI coding assistants into full-scale production studios. By utilizing a pipeline-driven architecture, it automates the entire creative lifecycle—from research and scripting to asset generation and final composition—while ensuring human oversight at critical decision points. The project distinguishes itself by offering both high-end AI-generated video capabilities and a robust 'real-footage' workflow that utilizes open archives and stock media, effectively solving the problem of high-cost, low-quality AI video generation.

// key highlights

Supports 12 distinct production pipelines, including animated explainers, documentary montages, and podcast repurposing.

Features a reference-driven creation mode that analyzes existing videos to replicate pacing, style, and structure.

Integrates live web research to ground scripts in real-time data from sources like YouTube, Reddit, and academic databases.

Provides a flexible provider-agnostic architecture that allows users to swap between local open-source models and premium cloud APIs.

Includes rigorous quality gates, such as ffprobe validation and audio analysis, to prevent the generation of low-quality or 'slideshow-style' content.

Implements built-in budget governance with cost estimation and spend caps to ensure transparency and control over production expenses.

// use cases

Automated production of animated explainers, cinematic trailers, and social media content

Reference-driven video creation that analyzes existing clips to generate original, structured production plans

Real-footage documentary assembly using indexed archives and open-source media without requiring paid video generation APIs

// getting started

To begin, ensure you have Python 3.10+, Node.js 18+, and FFmpeg installed on your system. Clone the repository, run 'make setup' to initialize the environment, and open the project in an AI coding assistant like Cursor or Claude Code. You can then trigger a production by providing a natural language prompt, such as 'Make a 60-second animated explainer about how neural networks learn'.
