Introduction
OpenMontage is a groundbreaking open-source project that redefines video production by integrating it directly with your AI coding assistant. It's the world's first agentic video production system, empowering users to create high-quality videos from simple text prompts. With 12 distinct pipelines, 52 specialized tools, and over 500 agent skills, OpenMontage automates the entire video creation workflow, from initial research and scriptwriting to asset generation, editing, and final composition.
One of its most significant distinctions is its capability to produce "real video video" using free and open stock footage and archives, rather than just animating still images. This allows for the creation of documentary-style montages and other motion-led content without relying solely on paid video generation APIs.
Installation
Getting started with OpenMontage is straightforward. Follow these steps to set up the environment and begin creating videos:
Prerequisites
- Python 3.10+: Download from python.org
- FFmpeg: Install via
brew install ffmpeg(macOS),sudo apt install ffmpeg(Linux), or from ffmpeg.org - Node.js 18+: Download from nodejs.org
- An AI coding assistant: Compatible with Claude Code, Cursor, Copilot, Windsurf, or Codex.
Install & Run
- Clone the repository:
git clone https://github.com/calesthio/OpenMontage.git - Navigate into the project directory:
cd OpenMontage - Run the setup command:
make setup
Once installed, open the project in your AI coding assistant and provide a prompt to start your video production. You can optionally add API keys for various providers (e.g., OpenAI, ElevenLabs, Fal.ai) to unlock more advanced tools and capabilities, though many features work out-of-the-box with zero keys.
Examples
OpenMontage can handle a wide range of video production tasks. Here are a few examples of prompts you can use with your AI coding assistant:
Animated Explainers
- "Make a 60-second animated explainer about how neural networks learn"
- "Make a 45-second animated explainer about why the sky is blue"
Real-Footage Documentary
- "Make a 75-second documentary montage about what a city feels like at 4am. Use real footage only, no narration, elegiac tone, with music."
- "Cut together a dreamlike montage about coming home in the rain using real stock footage only. Music yes, narration no."
Reference-Driven Creation
- "Here's a YouTube short I love. Make me something like this, but about CRISPR for high school students."
- "I like the pacing and hook in this video. Keep that energy, but turn it into a 45-second explainer about black holes."
Why Use OpenMontage?
OpenMontage stands out from other AI video tools by offering a comprehensive, production-grade approach to video creation:
- End-to-End Production Pipelines: Unlike tools that generate single clips, OpenMontage provides 12 complete production workflows, from concept to final render, mimicking a professional production team's process.
- Real Footage Capability: It can build finished videos from actual motion footage pulled from free and open sources, semantically ranked and intentionally edited, not just animated still images.
- Extensive Toolset: With 52 production tools and over 400 agent skills, it covers video generation, image creation, text-to-speech, music, audio mixing, subtitles, and more.
- Reference-Driven Creation: Start with a video you like, and the agent will analyze it to create a grounded, differentiated production plan, saving you from inventing perfect prompts from scratch.
- Live Web Research: Before scripting, the agent conducts extensive web searches across various platforms to ensure your video is grounded in real, current information.
- Flexibility with Providers: Supports both free/local open-source alternatives and premium cloud APIs, allowing you to use what you have and avoid vendor lock-in.
- Production Governance: Features quality gates, a scored provider selection system, an auditable decision trail, and budget controls to ensure high-quality outputs and predictable costs.
