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.

"The Library at Alexandria" — a 70-second history elegy on what humanity lost in a single night. Five hand-authored scenes — an illuminated manuscript page, cascading scroll-tags, a Burning Counter ticking 700,000 → 0 inside a candle's flame, a charred vellum fragment with surviving Greek, and an empty void — set to OpenAI 'ash' narration and a free Pixabay strings score. Total cost: $0.02. Built through OpenMontage's atelier (bespoke) composition mode — every scene crafted from scratch, no shared components.

"VOID — Neural Interface" — a product ad produced with just one API key (OpenAI). 4 AI-generated images (gpt-image-1), TTS narration, auto-sourced royalty-free music, word-level subtitles via WhisperX, and Remotion data visualizations. Total cost: $0.69. Zero manual asset work.

"Afternoon in Candyland" — a Ghibli-style anime animation. A little girl's whimsical afternoon adventure through candy gates, gumdrop rivers, and lollipop gardens. 12 FLUX-generated images with multi-image crossfade, cinematic camera motion (zoom, pan, Ken Burns), sparkle/petal/firefly particle overlays, and ambient music with auto-detected energy offset. Total cost: $0.15. No video generation, no manual editing.

"Mori no Seishin" — a Ghibli-style anime animation of a forest spirit's journey through ancient woods. 12 FLUX-generated images with parallax crossfade, drift and pan camera motion, firefly and petal particles, cinematic vignette lighting, and ambient forest soundtrack. Total cost: $0.15. Still images brought to life through Remotion's animation engine.

Start From A Video You Already Love

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:

Paste a reference video
The agent analyzes transcript, pacing, scenes, keyframes, and style
You get 2-3 differentiated concepts, an honest tool path, cost estimates, and a sample before full production

"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:

What it keeps from the reference: pacing, hook style, structure, tone
What it changes: topic, visual treatment, angle, narration approach
What it will cost at your target duration, before asset generation starts
What it will actually look like with your currently available tools

Works with Claude Code, Cursor, Copilot, Windsurf, Codex — any AI coding assistant that can read files and run code.

Watch It Happen — The Backlot Living Storyboard

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:
