TL;DR
OpenMontage turns natural language descriptions into fully produced videos through 11 pipelines and 400+ agent skills.
§01

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.

§02

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.

§03

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.
§04

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.

Frequently Asked Questions

What types of videos can OpenMontage produce?+

OpenMontage supports 11 pipeline types including animated explainers, talking head videos, screen demos, cinematic trailers, and more. Each pipeline encodes specific production patterns optimized for that video style.

Does OpenMontage require GPU hardware?+

It depends on the pipeline. Simple animated explainers can run on CPU. Pipelines that use AI-generated footage or local image generation models require a GPU. Cloud API-based generation (Runway, Kling) offloads compute to external services.

What AI services does OpenMontage integrate with?+

OpenMontage integrates with ElevenLabs for voice synthesis, Kling and Runway for video generation, Google Veo for video, and OpenAI for scripting and planning. It also supports local alternatives like Piper TTS.

Is OpenMontage free to use?+

The software itself is free and open-source under AGPLv3. However, most pipelines rely on external AI APIs (ElevenLabs, OpenAI, Runway) which have their own pricing. Local-only setups are possible but with reduced quality.

How does OpenMontage compare to manual video editing?+

OpenMontage automates the full pipeline from script to render. Manual editing gives you precise creative control. OpenMontage is best for producing content at scale or creating first drafts quickly, while manual editing is better for polished one-off productions.
