About this tool
What is the AI Film Storyboard?
The ReelStack AI Film Storyboard takes a film idea, ad concept, trailer, or music-video brief and breaks it down into a complete shot list with copy-ready prompts for every shot. Pick the visual style axes first (camera body, focal length, film stock, lighting, atmosphere — the same axes the Prompt Builder exposes) and the storyboard locks them across every shot so the look stays consistent.
The output is a structured shot-by-shot deck: for each shot you get an image prompt (paste into Midjourney / Flux / nano banana), a video prompt (Runway / Kling / Sora), a sound-design prompt (ElevenLabs SFX or human Foley brief), and the on-screen copy if any. The style lock means shot 1 and shot 9 share the same cinematography signature — no rewriting "Arri Alexa Mini, anamorphic, Kodak 5219" into every prompt by hand.
Use cases: pre-production for short films, ad campaign storyboarding, music video shot planning, pitch decks, and turning a paragraph-long brief into something you can actually generate. Beta, free, rate-limited at 10 per hour.

Questions about the AI Film Storyboard
How is this different from a basic 'AI storyboard generator'?
Most AI storyboard generators just produce vague text descriptions. This tool outputs FOUR coordinated prompts per shot — image prompt (for Midjourney/Flux/nano banana), video prompt (for Runway/Kling/Sora), sound design prompt (for ElevenLabs SFX or human Foley), and on-screen copy. Plus the style lock keeps every shot visually consistent.
What kinds of projects work best?
Ads (30s-60s), music videos (3-4 minute), short films (1-10 min), trailers, and pitch decks. It works less well for very long-form narrative (feature scripts) because the model loses thread across many beats — use it scene-by-scene instead.
Can I edit the storyboard after generation?
Yes. Every shot's image prompt, video prompt, sound prompt, and copy are individually editable. Regenerate a single shot without redoing the whole storyboard. Style lock stays applied to regenerated shots.
What does 'style lock' actually do?
When you pick visual axes (camera, lens, film stock, lighting, atmosphere, grade) before generating, those exact strings are appended to every image/video prompt in the storyboard. Shot 1 and shot 9 share the same look — no model drift, no rewriting cinematography vocabulary into each prompt.
