OpenMontage: agentic video production. Turns AI coding assistants into a full studio.

In simple English

This tool turns your text prompts into complete videos by working with your AI coding assistant. It handles everything from writing the script and finding stock footage to generating AI clips, adding voiceovers, and editing the final cut. You can use free offline tools or connect paid cloud services if you want high-end graphics. It saves you from learning complex video editors when you just want to ship content.

What it is

A Python-based agentic video production system with over twelve pipelines, one hundred tools, and hundreds of skill files. It coordinates AI models, local renderers, and open archives to build videos from plain language instructions.

What it is good for

Solo builders and content creators who want to automate video creation for marketing, tutorials, or social media without wrestling with professional editing timelines.

Good
  • Runs entirely on free local tools if you do not want to pay for cloud APIs.
  • Provides complete production pipelines from web research to final subtitle rendering.
  • Includes a live visual board to inspect and approve scenes before they render.
Watch for
  • Requires comfort with the command line and setting up Node.js alongside Python.
  • Paid video and image models can rack up costs quickly if you run them without limits.
  • The strict AGPL licence restricts how you can modify and host this code in commercial products.
Replaces

Manual video editing in Premiere or CapCut and stitching prompts across multiple separate web apps.

Works well with

FFmpeg (a command-line tool to convert, record, and stream audio and video)
