Seedance 2.5 プロンプトガイド（前編）：プロンプト構成と参照生成

Asset mapping + one-sentence brief + timeline or shot order + global constraints

Asset mapping:
Images 1–2: Character A's appearance; Audio 1: Character A's voice.
Image 3: Character B's appearance; Audio 2: Character B's voice.
Video 1: Reference only the two characters' action order.
Video 2: Reference only the orbiting camera and editing rhythm.
Image 4: Reference only the warm golden backlight and film color; do not reference the people.

Starting at second 4, rack focus: the sharp glass in the foreground gradually softens while the woman in the background moves from blurred to sharp. The focus transition is smooth and the camera position does not change.

Use Video 1 only for the complete shot order, camera positions, framing changes, subject paths, and timing. Do not copy the blockout materials or character appearance. Images 2–10 constrain the character design, environment, and color at each corresponding stage.

Generate a 30-second, 16:9 cinematic 3D fairytale animation: a girl launches a toy airplane in her bedroom, enters a fantasy sky, dives toward the ocean and underwater, crosses a space-time rift into space, then returns to the carpet asleep as her father enters the frame.

0–3 seconds corresponds to Image 2; 3–5 to Image 3; 5–8 to Image 4; 8–10 to Image 5; 10–19 to Images 6–7; 19–23 to Image 8; 23–28 to Image 9; 28–30 to Image 10. Preserve Video 1's shot structure exactly, add no new shots, and keep character appearance consistent with each corresponding keyframe.

Fully re-render Video 1 while preserving its action paths, camera movement, timing, and framing exactly.

Replace the environment with a cyberpunk night city in deep blue and violet. Dense skyscrapers carry holographic ads and neon reflections while distant aircraft move slowly between them. The subject is a small raccoon in a black stealth suit, carefully crossing a rooftop, its silhouette rim-lit by the city behind it.

No background music. Keep only wind, distant mechanical ambience, footsteps, and fabric movement. Do not generate motion paths, axes, or camera guides.

Asset mapping: Image 1 defines the order, framing, and camera rhythm of nine shots. Image 2 defines the composition and warm/cool palette of a grassland launch site at dusk. Image 3 defines an elderly woman in a golden-yellow dress. Image 4 defines a tall, weathered teal guardian robot.

Generate a 30-second, 16:9 live-action disaster-film sequence. Use 35mm color-film grain, subtle handheld breathing, and shallow depth of field. Contrast warm golden sunset, cool dusk blue, and explosive orange. No black-and-white, illustration, storyboard line art, toy-like rendering, or plastic CG.

Follow Image 1's nine-shot order: the pair watch the rocket from afar; the robot supports the woman; a close-up farewell; rocket liftoff; explosion in the sky; a tear falls; the woman collapses; the robot bends down and wraps around her protectively; end on a wide shot of the embrace. Dialogue is natural English. Place ambience, wind, and explosion sounds accurately.

Use Images 1 through 6 in order as keyframes for a 15-second vertical pixel-art science-fiction short. Keep a deep-blue space background, consistent 16-bit pixel texture, and retro electronic music throughout. Connect all frames through one continuous horizontal camera move.

Begin with the orbital station exterior in Image 1. After the camera passes through a window, the space courier in Image 2 turns toward the lens. In Image 3, she removes a glowing energy core from a storage bay. When the alarm lights activate, she moves through the zero-gravity corridor in the pose shown in Image 4, then leaps across a broken catwalk using the action in Image 5. The camera keeps following and enters the reactor chamber in Image 6, where she inserts the core and the room lights change from red to blue.

Keep her face, orange-and-white spacesuit, energy-core design, and station architecture consistent. Motion must remain continuous. No text, subtitles, flicker, or element deformation.
