如何为 Seedance 写提示词

Mara (@mara) is a young woman in a yellow raincoat; the street is a narrow cobbled lane at dusk.
Shot 1: Mara (@mara) walks toward the camera along the lane, slowly lowering her hood with her right hand as the rain eases. The camera tracks backward in front of her at walking pace.
Shot 2: She stops under a lit shop sign, looks up at the clearing sky, and lets out a long breath, shoulders dropping. Static medium close-up.
High definition, rich detail, cinematic texture. Her face stays stable without distortion; movement is natural and smooth, with no flicker.

Goal: Generate [kind of video]. The core subject is [subject]; the principal event is [one-line summary].
Inputs: [Name] is [@handle]; use only the face, hairstyle and clothing. @image2 is [the place]; use only its layout and light, not the people in it.
Positions: [Fixed features, who stands where relative to doors and tables, who holds what.]
Script: At the start: [state]. Shot 1: [...] Shot 2: [...] At the end: [final positions, who holds what].
Keep the same: [Identities and count, clothing, who owns which prop, directions, which voice belongs to whom.]

Rooftop chase at sunrise, saturated color.
0-3 seconds: [Wide shot, locked off] A cyclist in a red jacket sprints across a flat rooftop toward the edge.
3-6 seconds: [Extreme close-up, low angle] The front wheel leaves the edge against the orange sky.
6-10 seconds: [FPV, following] The bike lands on the next roof and skids to a stop, and the rider punches the air, the city spread out below.
The sound includes wind, the hum of the tires, a hard landing thud, and a distant siren.

Goal: Generate a tense dialogue scene in a candlelit tent at night. Hatim offers bread to a guest who hides a dagger.
Inputs: Hatim is @hatim; use only his face, head wrap and cloak. The guest is @guest; use only his face, head wrap and travel cloak.
Positions: Hatim sits on the west side of a low rug, the guest on the east side, a clay plate of bread between them. The camera stays south of them.
Script:
Shot 1: [Medium two-shot from the south, locked off] The guest's right hand rests on a sheathed dagger under his cloak. Hatim tears bread and holds out a piece. Hatim's line (in English, warm): {Eat. You are my guest.}
Shot 2: [Close-up on the guest, slow push in] His eyes move from Hatim's face to the bread. He lets go of the hilt and takes the bread with that same hand. Hatim keeps his mouth naturally closed.
Shot 3: [Medium two-shot from the south, locked off] Both men eat in silence. End with the bread in the guest's hand and the dagger still sheathed.
Keep the same: Two men only, seats unchanged, the dagger stays sheathed. No subtitles. Sound: candle crackle, cloth rustle, wind against the tent.

Edit: Edit video 1, replacing only the red bicycle and its rider with the dark-gray electric patrol cart from @image1.
Source video: video 1 is the sole editing master and governs the park path, the two people on the bench, the camera, the rider's motion and the event order.
New material: @image1 is used only for the cart's body, color and clear windshield; do not use its background or driver.
Scope: There is exactly one cart throughout. Except for the objects explicitly modified above, all other visible characters, props, and background elements in video 1 remain unchanged and are not to be replaced or removed.
Timing: The cart takes the rider's exact timing, path, speed and occlusion in front of the bench. The bicycle and rider no longer appear.
