OpenMontage is the world's first open-source, agentic video production system. It orchestrates the full workflow — research, scripting, voiceover, image & video generation, editing, and final render — driven by your AI coding assistant. Not isolated clips: complete productions.
What it does
Agentic Orchestration
Reads YAML pipelines & markdown skills, then runs each stage automatically via Claude Code, Cursor, Copilot, Windsurf or Codex.
12 Full Pipelines
Animated explainers, cinematic trailers, documentary montages, talking heads, screen demos, podcast repurposing and more.
52 Production Tools
14 video-gen providers (Kling, Runway, Grok, local), 10 image tools, 4 TTS engines, plus music, avatars & lip-sync.
Live Research First
Runs real web research before writing the script, and can analyze a reference video's transcript, pacing, scenes and style.
Quality & Budget Gates
Production-grade quality checks, cost controls, and a 7-dimension scored provider selection so you stay on budget.
Backlot Board
An optional local production board to monitor each render live while the agent works through the pipeline.
Get started (Windows)
Clone the repository
Grab OpenMontage from GitHub into a folder of your choice.
git clone https://github.com/calesthio/OpenMontage.git
cd OpenMontage
Install dependencies
The repo ships a make setup target. On macOS/Linux run it directly; on Windows, install a make tool first (or run the Makefile steps manually — I can translate them for you).
# after installing make on Windows:
winget install GnuWin32.Make
make setup
Add your API keys
Copy the example environment file and drop in keys for whichever providers you want (many free/local options work with no keys at all).
copy .env.example .env
notepad .env
Produce your first video
Open the cloned folder in your AI coding assistant (Claude Code, Cursor…) and just ask it to make a video. It reads the pipelines and renders an MP4 to disk.
