name: jet-dogfight-generator
description: Create cinematic 7-second MiniMax H3 text-to-video clips of high-speed jet dogfights above and through cloud decks. Full real-time speed, vapor cones, contrail arcs, G-load haze and sun flare on canopies; the camera orbits and whips with the airframes. No slow motion, no external footage feel — one continuous aerial shot. T2VA only, no reference material needed.
compatibility: Portable to agents that can read local files and use MiniMax H3. Use H3-Base-FL2VA in T2VA mode.
trigger-words: [jet dogfight, air combat, fighter jet, 空战, 战机, 缠斗, 俯冲, 高空, 凝结尾迹, dogfight, aerial combat]

# Jet Dogfight Generator
Default:
- Model: H3-Base-FL2VA
- Mode: I2VA (reference image first); T2VA fallback supported
- Duration: 7s
- Aspect ratio: 16:9
- Primary Motion Owner: the dogfighting airframes
- Tempo: Energetic — full real-time speed; slow motion prohibited for the subject
## Reference-First Workflow（参考图路线，推荐）
优选 **I2VA**：先用图像生成模型产出首帧参考图（见 `references/prompt-library.md` 的 P-IMG），
再让 H3 按图动起来——机型、音锥与凝结尾迹的视觉由图保底，文字只负责机动与镜头。
1. 按 P-IMG 的构图要求生成 16:9 参考图（大广角高空、双机对头占对角、云海平面居中）。
2. 用 P1-I2VA 模板生成 7s 视频；首帧必须与图同构图、同机型。
3. 没有图像生成条件时，降级 P2-T2VA 纯文字模板（结果取决于文字质感，非首选）。
## Global Motion Principles
These rules override decorative cinematic language. This Skill's whole identity is speed.
### Motion Ownership
- The airframes own all primary motion: the head-on pass, the pull, the vertical zoom. Contrails, vapor cones, cloud tears and heat haze accompany but never replace the move.
+ The airframes own all primary motion: the closing approach, the crossing, the separation. Contrails, wing-tip filaments and heat haze accompany but never replace the move.
If the jets never visibly maneuver at real speed with crisp G-loading, the generation fails even if the shot is beautiful.
### The Speed Rule
- - **No slow motion for the subject — ever.** Prefer explicit language: `The jets maneuver at full real-time speed, snapping through the turn at high G.`
- - At least two acceleration events: the head-on merge and the vertical zoom breakaway.
- - Exactly one Impact peak (the vertical zoom out of the cloud deck / canopy flash, placed at 70–90% of the clip).
- - Airframes stay physically coherent: correct wing flex, vapor cone placement, no gliding physics.
+ - **No slow motion for the subject — ever.** Prefer explicit language: `Both jets maneuver at full real-time speed, noses locked to their headings.`
+ - One continuous event per clip: the merge (close → cross → separate).
+ - Exactly one Impact peak — the high-speed crossing at 70–90% of the clip, sonic crack and contrail X.
+ - Aircraft grammar: nose always aligned with flight path, no sideways slide, no pivot in place, contrails attached to the actual path and bending smoothly with any bank.
### Camera
- Three camera landmarks, all participating in speed:
+ One dominant camera behavior:
- 1. **High-altitude head-on hold** — camera static against the cloud deck while the jets close fast (first second).
- 2. **Orbit whip** — camera whips around the lead airframe as it pulls, contrails carving arcs through the sky (mid-clip).
- 3. **Breakaway zoom & wide reset** — at the peak the jets zoom vertically out of the cloud top, sun flare on the canopy; camera pulls back to a wide high shot over the cloud sea (last second).
+ 1. **Locked high-altitude hold** — the camera holds absolutely still at altitude for the whole clip; closing speed is read from the two airframes growing in frame.
+ 2. **No whip, no orbit, no vertical moves** — the crossing does the drama; horizon stays level, screen direction never reverses.
- Camera follows G-forces; the horizon tilt reads the load. Never a cruise-by fly-over.
+ Never follow with the lens what the nose of the aircraft can do on its own.
## Texture & Scale Requirements (the epic look)
- **Sky as a stage with weather**: named cloud system (uniform stratus-like sheet layer / thin broken cirrus at altitude — avoid cell-like cumuliform words such as stratocumulus) that visibly tears around the jets.
- - **Speed artifacts**: vapor cone at the canopy, contrail pairs, wing-tip vortices, heat-haze shimmer off the exhaust.
+ - **Speed artifacts**: contrail pairs, faint wing-tip condensation filaments, heat-haze shimmer off the exhaust — no vapor cones.
- **Light as an accent**: sun flare on the canopy, low golden side-light on the airframe, cloud shadows streaking past.
- **Two surface details minimum**: panel lines and rivets, paint wear, missile rails, pilot helmet silhouette in the canopy.
- - **One color temperature** (stratosphere blue / dusk amber / dawn violet) plus one light accent.
+ - **One color temperature** (high-altitude golden / dusk amber / dawn violet) plus one light accent.
## Prompt Structure
Official three-field layout (see `h3-prompt-writing`):
```text
- integrated_multimodal_description: [Shot 1] <head-on hold, jets closing at real speed> <converge + vapor cone burst> <orbit whip, contrails arc, cloud tears> <Impact peak: vertical zoom out of the deck, canopy flare> <wide reset over the cloud sea> — time brackets per beat.
+ integrated_multimodal_description: [Shot 1] <locked hold, jets closing at real speed from opposite corners> <stable level approach toward center, noses locked to headings> <separation banks, contrails bowing> <Impact peak ~70%: clean high-speed crossing + sonic crack, contrail X> <both jets recede to opposite edges, contrail X settles> — time brackets per beat.
- overall_soundscape: <jet roar building> + <sonic crack at the merge> + <wind shear hiss during the orbit>.
+ overall_soundscape: <jet roar building steadily> + <sharp sonic crack at the crossing> + <wind hiss fading as the pair separates>.
- non_diegetic_music: <pulsing electronic pulse and low percussion> accelerating to the peak, breaking into open air on the wide reset.
+ non_diegetic_music: <pulsing percussion and strings> accelerating to the crossing, breaking into open air as the contrail X settles.
```
Rules:
- One continuous shot — no cuts, no montage, no grid, no text overlays.
- English body copy. Time brackets per beat.
- The Impact peak gets the strongest verb; the zoom is a single burst, not a loop.
- Never exceed 7s; the wide reset lands in the final second.
