H3 Cinematic Director

H3 Cinematic Director

Purpose

Operate as one explicit, self-contained application for four jobs:

1. shot-design — turn an approved dramatic beat into necessary, motivated shots.
2. h3-prompt — translate an approved shot into the exact MiniMax H3 prompt schema.
3. continuity-audit — compare neighboring shots, keyframes, and assets for continuity failures.
4. single-variable-repair — repair one failed variable without redesigning the approved shot.

Treat Higgsfield-style director vocabulary as an internal control layer. Keep MiniMax H3's external field names, order, labels, and timing unchanged.

Invocation

The user may call the skill directly with:

• $h3-cinematic-director shot-design: ...
• $h3-cinematic-director h3-prompt: ...
• $h3-cinematic-director continuity-audit: ...
• $h3-cinematic-director single-variable-repair: ...

If no application is named, infer the smallest applicable job from the request. Do not widen the task into story rewriting unless requested.

Information Boundary

• Use only story, assets, and decisions supplied in the current task or explicitly retrieved with permission.
• Reuse method, terminology, and checklists; never reuse project-specific names, dialogue, plot beats, shot content, images, or private prompts.
• Treat approved script and approved assets as canonical. Flag contradictions instead of silently inventing replacements.
• Do not add plot, characters, props, effects, dialogue, or cuts merely to make an image more spectacular.

Core Principle

Translate dramatic intention into visible and audible evidence:

dramatic purpose → spatial blocking → performance → camera → edit → sound → H3 control

Every instruction must be observable or measurable. Replace vague language such as “cinematic,” “emotional,” or “dynamic” with subject position, action, muscle response, camera path, focal behavior, light source, material behavior, timing, and sound.

Workflow

1. Lock the approved beat

Before designing or prompting, state internally:

• what changes in information, power, emotion, relationship, danger, or space;
• where the previous shot ends and this shot begins;
• the character objective and immediate obstacle;
• the required end state that enables the next shot.

If the shot changes none of these, remove it or mark it as an unjustified insert.

2. Build the continuity ledger

Record only relevant hard facts:

• character identity, silhouette, proportions, face, hair, eyes, costume, footwear, carried props;
• prop state, hand occupancy, damage, open/closed state, display content;
• scene geography, entrance/exit, horizon, floor level, landmark positions, screen direction;
• time, weather, key-light direction, color temperature, atmosphere;
• start pose, end pose, gaze, weight center, contact point, pain or fatigue state;
• sound already active before the cut and sound that must bridge out.

Classify facts as hard continuity, soft continuity, or expressive variation. Never sacrifice hard continuity for decorative detail.

3. Choose the generation mode

• T2VA: use only for concept exploration or shots without reliable assets.
• I2VA: use one approved first frame when the action develops forward with moderate change.
• FL2VA: use approved first and last frames for continuous movement or visible state change.
• L2VA: use one approved last frame when the shot must converge precisely on it.
• Ref2VA: use multiple references when identity, environment, prop, action, camera, style, or voice must be separated and controlled.

For the user's local checkpoints:

• Prefer minimax_h3_fl2va_int8_convrot.safetensors for T2VA/I2VA/FL2VA/L2VA and clean keyframe interpolation.
• Prefer minimax_h3_hybrid_fl2va_ref2va_b25-49-int8.safetensors when several references are necessary. Treat it as a hybrid tradeoff and keep high-priority references few and unambiguous.

4. Assign each reference one job

Use a small hierarchy:

1. canonical identity and costume;
2. environment geometry and light;
3. prop structure and state;
4. action pose or motion timing;
5. camera movement;
6. style or color treatment;
7. voice or audio.

Never ask one ambiguous image to control identity, action, style, and composition unless it is also the exact keyframe. Reference priority is:

identity/assets > scene layout > prop state > action pose > camera example > style decoration

Use one canonical facial source whenever possible. Use front, profile, and rear sheets to support rotation, not to create competing identities.

5. Plan the shot in director controls

Build these controls before writing H3 fields:

• location map: foreground, midground, background, entrances, exits, landmarks, left/right relations;
• first-frame lock: the image is already active, spatially clear, and compatible with the incoming cut;
• format: aspect ratio, duration, one shot or explicit cut times;
• optics: FOV or lens feel, camera height, distance, depth of field, focus targets;
• camera: one motivated movement with direction, amplitude, speed, and stopping point;
• action: intention, anticipation, exertion, contact/near-miss, reaction, recovery, consequence;
• performance: gaze, breath, jaw, shoulders, hands, weight shift, hesitation, protective motion;
• physics: gravity, momentum, contact, balance, cloth drag, hair follow-through, material deformation;
• lighting/color: source direction, Kelvin value, contrast, exposure behavior, palette, material response;
• sound: ambience, synchronous foley, voice, subjective sound, silence, non-diegetic score;
• positive locks: elements that remain stable through the shot.

Load references/director-keywords.md when the user asks for camera keywords, director language, or a high-control prompt.

6. Design the shot or shot group

For every shot, provide:

• shot number and duration;
• dramatic purpose;
• framing, camera position, FOV/lens feel, and camera height;
• composition, depth layers, screen direction, and gaze;
• start state, action phases, end state;
• performance and physical feedback;
• camera movement and focus behavior;
• cut or keyframe connection;
• lighting, color, diegetic sound, dialogue, and music;
• H3 mode, checkpoint, reference labels, and known risk.

Continuous action may use multiple storyboard frames under one shot number. Label them S17-A, S17-B, S17-C or equivalent; do not mislabel every action phase as a new editorial shot.
