OpenMontage — AI Video Production System

What it is

OpenMontage is the first open-source agentic video production system. It takes a natural language description of a video and handles the entire production pipeline automatically -- from research and scripting to asset generation, editing, and final render. The system includes 11 production pipelines, 52 tools, and 400+ agent skills.

OpenMontage is built on Remotion (React video engine), FFmpeg, and Piper TTS. It supports external services like Kling, Runway, Google Veo, and ElevenLabs for higher-quality output. It is best for developers and content creators who want to automate video production with AI rather than editing manually.

How it saves time or tokens

Traditional video production requires separate tools for scripting, asset creation, editing, and rendering. OpenMontage collapses this into a single command. You describe what you want, and the agent system handles each stage. The 11 specialized pipelines (animated explainers, talking heads, screen demos, cinematic trailers, and more) each encode production best practices so you do not need to specify every detail.

How to use

1. Clone the repository: git clone https://github.com/calesthio/OpenMontage.git && cd OpenMontage.
2. Run setup: make setup and configure .env with your API keys.
3. Produce a video: python produce.py 'Create a 60-second animated explainer about how MCP servers work'.
4. The system will research, script, generate assets, edit, and render the final video.

Example

# Install and configure
git clone https://github.com/calesthio/OpenMontage.git
cd OpenMontage
make setup
cp .env.example .env
# Add API keys to .env

# Produce a video from a description
python produce.py 'Create a 90-second product demo for a CLI tool'

# Output lands in ./output/ as MP4

Common pitfalls

• API key configuration is required for most pipelines. Without ElevenLabs or similar TTS keys, voice generation falls back to Piper TTS which has lower quality.
• GPU requirements vary by pipeline. Animated explainers run on CPU, but cinematic trailers with AI-generated footage need significant GPU resources.
• The AGPLv3 license requires sharing modifications if you deploy OpenMontage as a service. Check license terms before commercial use.
