OpenMontage: Open-Source Agentic Video Production System for AI Coding Assistants
OpenMontage is an open-source video production system that turns AI coding assistants like Claude Code into full production studios. You type what video you need, and the agent handles the entire pipeline from research to final render.
What It Does
The system performs these specific tasks when given a video request:
- Researches the topic with live web search
- Plans scenes mixing AI-generated images with animated data visualizations
- Generates product shots
- Writes a narration script budgeted to fit the video duration
- Generates voice narration with direction like "speak like a keynote narrator"
- Automatically searches and downloads royalty-free background music
- Generates word-level subtitles with TikTok-style highlighting
- Validates the entire composition before rendering (catches audio-video mismatches, missing files)
- After rendering, reviews its own video and catches issues like wrong backgrounds, cut-off narration, or broken subtitles
System Components
The package includes:
- 11 production pipelines for different video types (explainers, product ads, cinematic trailers, podcasts, localization)
- 49 tools including 12 video generation providers, 8 image generation options, 4 text-to-speech systems, plus music, subtitle, and analysis tools
- 400+ agent skills
- Works with zero API keys using Piper TTS + stock footage + Remotion animation, or can be configured for full cloud setup
- Budget governance with cost estimates before execution, spend caps, and per-action approval
This isn't a SaaS platform or a simple prompt-to-clip tool. You give your coding assistant a prompt, guide its creative decisions, and it manages the complete production workflow.
