What's inside
Want to support OpenMontage? Sponsor the project.
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-second cinematic documentary about the mineral that funded empires, shaped trade routes, sparked revolutions, and gave us the word “salary.” Real-world footage is woven together with original narration and hand-authored motion graphics for its etched title, etymology reveal, animated maps, historical timeline, and closing thesis.
"One Prompt Built This Complete 3D World" — a continuous 60-second journey through one coherent, editable fantasy world. Distinct terrain regions, an inhabited village, waterways, ruins, dense vegetation, and a late hero-landmark reveal are assembled from textured 3D assets, then brought together with cinematic lighting, atmospheric music, and a planned camera path.
Starting from a reference video is often faster than starting from a blank prompt.
OpenMontage can start from a YouTube video, Short, Reel, TikTok, or local clip and turn it into a grounded production plan:
"Here's a YouTube Short I love. Make me something like this, but about quantum computing."
What you get back is not "best guess prompt spaghetti." You get:
Works with Claude Code, Cursor, Copilot, Windsurf, Codex — any AI coding assistant that can read files and run code.
Chat tells you what the agent said. Backlot shows you what the production is actually doing — a local board that fills itself in as the pipeline runs. Stages light up, the script lands as a screenplay page, scene cards shimmer while assets generate, and every provider decision and dollar spent is on the wall.
When a production starts, the agent opens it for you automatically. No setup, no reporting — the board derives everything from the project files the pipeline already writes.
The storyboard is now a real approval gate. Asset generation pauses on a scene-by-scene contact sheet — takes, prompts, per-asset cost, quality scores — so you approve the visuals before the render, not after it's too late:
Creative gates hold until you answer. The board shows what's waiting and why; you reply in chat:
Every production on your machine, live-first, in the library:
python -m backlot open # the library — every project on disk
python -m backlot open <project-id> # one production's live board
python scripts/backlot_simulate_run.py # no production yet? watch a simulated one live
And when a run is done, hit ▶ REPLAY RUN — the whole production replays from its timestamps, scrubbable end to end. See backlot/README.md for how it works.
