Project overview

OpenMontage provides an end-to-end video production pipeline that automates research, scripting, asset generation, and editing via AI coding assistants. It orchestrates structured workflows from natural language prompts or reference videos into finished video files using built-in validation checks.

Best for

• Creators and developers who need an orchestrated, multi-stage video production workflow automated through an AI coding assistant.

Key capabilities

• Orchestrates complete production workflows from idea to finished video through structured stages including research, proposal, script, scene_plan, assets, edit, and compose.
• Includes over 400 agent skills consisting of production skills, pipeline directors, creative techniques, and quality checklists that instruct the AI assistant on executing stages.
• Provides a local, auto-populating board that displays production progress, live stages, and assets currently generating. It also functions as a visual approval gate.
• Enforces pre-compose validation to block slideshow renders and conducts post-render self-review using ffprobe, frame extraction, and audio analysis to ensure outputs meet standards.
• Ranks tools across seven dimensions—task fit, output quality, control, reliability, cost efficiency, latency, and continuity—to automatically select a provider.

Limitations and risks

• The system requires an external AI coding assistant to function and cannot operate autonomously.

Getting started

• Clone the repository, navigate into the project directory, run 'make setup' to install dependencies, and open the project in an AI coding assistant to begin. The setup requires Python, Node.js, and FFmpeg.
