The gist

OpenMontage is an open-source, agentic video production system built to be operated by an AI coding assistant. It automates the entire video creation workflow, from initial research and scripting to asset generation, editing, and final composition. The system aims to replicate the structured process of a human production team, allowing users to generate complex videos from a single plain-language prompt within their code editor.

What it does

Automate end-to-end video production pipelines, including research, scripting, asset generation, and composition.
Generate videos from AI-generated images, complete with narration, music, and animated effects.
Assemble documentary-style montages using real motion footage from free stock and open archival sources.
Analyze a reference video (YouTube, TikTok) to create a new production plan based on its style and pacing.
Repurpose long-form content like podcasts into multiple short-form social media clips.
Localize and dub existing video content with subtitles and translated voiceovers.

How it works

A user provides a text prompt to their AI coding assistant within the OpenMontage project. The agent then acts as an orchestrator, executing predefined production pipelines by reading Markdown skill files and calling Python tools. The system can run locally without any API keys by using built-in free tools for TTS and stock footage, or it can be configured with keys for premium providers. Output is a final rendered MP4 video file.

Best for

Developers and technical content creators who want to programmatically generate videos by giving high-level prompts to their AI coding assistant.

Watch out for

This is not a web-based tool. It requires a local development environment with Python, FFmpeg, and Node.js installed, and is operated through an AI-powered code editor.
