OpenMontage

Overview

GitHubGitHub

OpenMontage is an open-source agentic video production system designed to turn AI coding assistants (such as Cursor, Copilot, etc.) into a full-fledged video production studio. Simply describe your needs in natural language, and the Agent automatically handles research, scripting, asset generation, editing, and final compositing. Unlike conventional approaches that merely stitch static images into videos, OpenMontage supports creating truly dynamic videos. In free or open-source workflows, the Agent builds a corpus from free stock libraries and open archives, retrieves real motion footage, edits it onto a timeline, and renders the output. ### Key Capabilities - **Multi-pipeline support**: 12 built-in production pipelines covering the entire workflow from concept to final cut. - **Rich tools and skills**: Over 100 tools and 700+ Agent skills and production knowledge files. - **Reference video reverse-engineering**: Paste a YouTube video, Short, Reel, TikTok, or local clip as a reference. The Agent analyzes its transcript, pacing, scenes, keyframes, and style, then outputs 2–3 differentiated concepts, tool paths, cost estimates, and pre-production samples. - **Multi-model integration**: Compatible with OpenAI, ElevenLabs, Flux, Stable Diffusion, Kling v3, Veo, Remotion, FFmpeg, Blender, and other image, video, voice, and rendering tools. ### Use Cases & Audience Ideal for developers, creators, or teams looking to automate video production via natural language instructions. Whether it's Pixar-style animated shorts, sci-fi trailers, 3D product showcases, documentaries, or promotional videos, the system orchestrates different model and tool combinations to deliver them. Written in Python and open-sourced under the AGPL-3.0 license.

Q&A

Is OpenMontage free?AI-generated

OpenMontage itself is an open-source project under the AGPL-3.0 license. It supports producing videos using free stock libraries and open-source workflows, but calling certain third-party AI models (such as Kling v3, Veo, etc.) may incur API costs. Costs mentioned in the original examples range from about $1.33 to $5.

Can OpenMontage only make videos by stitching images together?AI-generated

No. As explicitly stated, OpenMontage can produce not only image-based videos but also truly dynamic videos. The Agent can retrieve real motion footage from free stock libraries and open archives, edit it onto a timeline, and render the final video.

How do I use the reference video feature?AI-generated

You can paste a link to a YouTube video, Short, Reel, TikTok, or a local clip. The Agent will analyze the video's transcript, pacing, scenes, keyframes, and style, then provide you with 2–3 differentiated concepts, tool paths, cost estimates, and pre-production samples.

What programming languages and tech stacks does OpenMontage support?AI-generated

According to the repository information, OpenMontage is primarily written in Python and integrates tech stacks such as Remotion, FFmpeg, and Blender for video rendering and compositing.
