An agentic video production system that runs inside AI coding assistants, handling research, scripting, asset generation, editing, and rendering.
Why you might care
Lets you describe a video in plain language and have your AI coding assistant produce it through 12 pipelines and 100+ tools. It can assemble real motion footage from free stock and open archives, not only animated stills, and it is AGPL-3.0 licensed.

README excerpt
Monty the Clapper — the official mascot of OpenMontage OpenMontage The first open-source, agentic video production system. Paste A Video · Quick Start · Try These Prompts · Pipelines · How It Works · Providers · Review Guide · Agent Guide Follow The Build --- Turn your AI coding assistant into a full video production studio. Describe what you want in plain language — your agent handles research, scripting, asset generation, editing, and final composition. **Important distinction:** OpenMontage can make image-based videos, but it can also make a real **video video** for free/open-source workflows: the agent builds a corpus from free stock footage and open archives, retrieves actual motion clips, edits them into a timeline, and renders a finished piece. That is not the usual "animate a handful of stills and call it video" trick. > **"SIGNAL FROM TOMORROW"** — a cinematic sci-fi trailer fully produced through OpenMontage: concept, script, scene plan, Veo-generated motion clips, soundtrack, and Remotion composition. > **"THE LAST BANANA"** — a 60-second Pixar-style animated short about a lonely banana who finds friendship with a kiwi. 6 Kling v3-generated motion clips (via fal.ai), Google Chirp3-HD narration, royalty-free piano music, TikTok-style word-level captions, and Remotion composition. Total cost: **$1.33**. > **"OBJECTS IN OVERDRIVE"** — a 54-second, music-driven 3D showcase featuring ten objects with distinct choreography: gravity-shifting furniture, frozen car drifts, cloth impacts, refractive lenses, moving gears, an acrobatic robot, and more. Custom Blender animation and physics, kinetic typography, and a phonk soundtrack. Rendered with Blender Eevee/Cycles and assembled with FFmpeg. No narration. > **"Reimagine Your Universe"** — a 50-second vertical transformation film in which one visual idea moves across objects, eras, materials, and scale. Five generated motion scenes, sparse Google Chirp narration, a Pixabay score, and a bespoke HyperFrames composition turn separate clips into one authored cinematic journey. Total cost: **about $4**. > **"Products Come to Life"** — a 60-second product film built from approved hero stills. Five hard-surface products separate into their own engineering and reassemble, with each still pinned as the first and last frame so the model invents motion without losing product identity. Image-to-video generation, bespoke sound, narration, and a custom composition complete the film. > **"Imagine the Possibilities with OpenMontage"** — seven generated worlds collected into one music-only showcase. Three image models supply campaign, fashion, and miniature-world artwork; four video models expand the journey through architecture, material transformation, a living greenhouse, and a creature encounter. OpenMontage animates the stills, edits the motion, unifies the soundtrack, and closes with Monty the Clapper. Source generation cost: **about $5**. > **"How Salt Made History"** — a 100-
