muapi-ai-fight-scene
Generate a high-cut-density action / fight scene by first composing a 16-cell storyboard image, then driving Seedance 2.0 image-to-video off that storyboard. Stacks GPT-Image-2 (character sheet + storyboard), Nano-Banana-2 (environment concept), and Seedance 2.0 i2v.
Why this skill is useful
Adds a complete workflow for generating high-density action scenes with executable prompts and structured outputs that the AI cannot generate on its own.
What it needs

What this skill does
AI Fight Scene Generator Generate a high-cut-density action / fight scene by first composing a 16-cell storyboard image, then driving Seedance 2.0 image-to-video off that storyboard. The core idea: action tension comes from cut density, not single-shot quality. Forcing the video model to follow a pre-drawn 4×4 storyboard grid gives you 16 distinct shots in a 15-second clip — landing punches, reverse angles, ECUs, whip-pans — that no t2v prompt could choreograph on its own. Inputs Name Type Required Default Description :--- :--- :--- :--- :--- characterdescription text yes — Full physical description of the fighter(s). Asymmetric details (eye colour, scar side, holster on left hip) help the model preserve identity across panels. environmentdescription text yes — The scene setting — e.g. "cyberpunk wet back-alley, neon kanji signage, Stray-game aesthetic, rain on chrome." actionscript text yes — The action beat — prose or numbered beats. E.g. "Hero is cornered → blocks first punch → counter-elbow → throw opponent into trash cans → finisher." styledirection text no cinematic action film, anamorphic lens, high contrast, motion blur on hits Aesthetic / look tags applied to every frame. duration int no 15 Final video length in seconds. The storyboard's 16 cells map roughly 1 shot per second at default. aspectratio text no 16:9 Output aspect — 16:9 cinematic, 9:16 vertical, 1:1 square. Steps Phase A — Character Sheet Generate a clean turnaround-style character sheet using muapi image generate (model=gpt-image-2-text-to-image): Prompt: Character reference sheet of {{characterdescription}}. Three views — front, 3/4, profile — on a neutral grey backdrop. Studio lighting, full body, no text overlays, photoreal. Asymmetric identifying details preserved on the correct side. {{styledirection}}. Aspect ratio: 3:2 Present the character sheet and confirm identity details look right before proceeding. This image becomes reference #1 for later phases. …
