What is the Cinematic Sheet Composer?
The Cinematic Sheet Composer is the only free prompt composer purpose-built for multi-panel AI image grids — the 3x3 angle sheet, 9x9 storyboard, 2x3 ad sequence, or 5-cut pre-production brief format that working filmmakers actually use. You pick what varies across the panels (camera angles, narrative beats, emotions, time of day, environments, poses, product variations, full ad storyboard, or a 5-cut director brief), pick the layout, lock a visual style, and the composer assembles fragments from a curated cinematography database, then runs a single Gemini 3 Flash smoothing pass for natural-language flow.
The output is a single, structured prompt designed to render a coherent sheet in one generation — not nine separate prompts you have to manually align. Take it to nano banana, Midjourney, Flux, GPT Image 2.0, Imagen 3, or any compatible image model. No platform lock-in; the prompt is portable.
Filmmakers use this for character turnarounds, location plates, ad-campaign mood boards, music-video pre-pro, and shot-list visualization. Beta-tier, free, rate-limited at 10/hour to keep the Gemini smoothing pass affordable.

Questions about the Cinematic Sheet Composer
What's a 'cinematic sheet'?
A grid of related shots — 3x3 character turnaround, 9-panel storyboard, 2x3 ad sequence, 5-cut director brief — generated as a single AI image so the panels stay visually consistent. Filmmakers use them for pre-production, mood boards, and pitch decks.
Which AI image models work?
Any text-to-image model that handles multi-panel prompts well. Tested on nano banana, Midjourney v7, Flux Pro Ultra, GPT Image 2.0, Imagen 3, and Sora's image mode. The composer outputs a portable prompt — no platform lock-in.
What's the difference vs. the Prompt Builder?
Prompt Builder makes a single-shot cinematic prompt (one image). Cinematic Sheet Composer makes a multi-panel grid prompt (one image with 4-9 coordinated panels). Use Sheet Composer for character refs, storyboards, ad sequences. Use Prompt Builder for one-off hero shots.
Is it really free?
Yes. Beta tier, no signup required. Rate-limited at 10/hour to keep the Gemini 3 Flash smoothing pass cost affordable for us. Sign in to a ReelStack account for 50/day.
What's the 5-cut pre-production brief?
A director's brief layout: hero wide → med 2-shot → close on subject → cutaway → final beat. The composer generates a prompt that renders all 5 in a single panel with consistent lighting, framing, and grade — useful for pitching a commercial concept in one image.
