seedance 提示詞：重型摩托車品牌廣告（霧中山路—暴雨岔路—山頂揭曉 · 懸念式汽車廣告結構）

時長與鏡頭：原作 30 秒六場，本站壓縮到 15 秒五段。更穩的做法是拆成兩條：第一條 0–9 秒（霧中出現、追逐、暴雨岔路），第二條 9–15 秒（山頂揭曉 + 產品環繞），第二條用第一條最後一幀接上。

結構值得學：高端汽車 / 摩托車廣告常用"先講故事、最後才亮產品"——前 2/3 完全不像廣告，製造懸念（她要去哪、誰在追她），到最後揭曉"她是在尋找這個地方"，產品作為旅程的一部分登場。這比開場就懟產品特寫更有記憶點。色調從冷到暖的變化，也在暗示情緒從緊張到釋然。

怎麼填變量：[重型摩托車] 換成"越野車""電動皮卡""公路自行車"，並上傳產品圖作 @圖片1。人物可以換成男性騎手，或者乾脆不摘頭盔，保持神秘感。

常見失敗與調整：

• 摩托車每個鏡頭都不一樣：多給幾張不同角度的產品圖（參考圖數量上限以官方當前說明為準），並寫"車輛外觀嚴格以參考圖為準"。
• 產品環繞段車身變形：環繞角度改小，或最後用實拍產品素材替換。
• 雨夜太黑：寫"閃電和車燈提供足夠的光線"。

Create a 30-second premium cinematic advertisement centered around a powerful heavy motorcycle and a striking adult female rider.

The film should initially feel like a serious, high-budget cinematic action thriller — NOT a motorcycle commercial.

For the first 20 seconds, create mystery and tension. The audience should wonder where she is going, what she is searching for, and why she is riding alone through such a dangerous environment.

The motorcycle should feel heavy, powerful, expensive and mechanically realistic.

The story should naturally build from:

MYSTERY → PURSUIT → DANGER → DESTINATION → REVEAL → HERO PRODUCT

Do NOT copy any existing advertisement, film, commercial, character, composition, scene or visual sequence. Create an entirely original story.

VISUAL STYLE

Photorealistic cinematic filmmaking.

Premium high-budget automotive commercial production.

Large-format cinema look with 35mm anamorphic photography.

Deep cinematic contrast, natural skin texture, realistic motorcycle materials, metal, leather, glass and rubber.

Realistic engine vibration, suspension movement and mechanical motion.

Subtle film grain, natural motion blur and realistic environmental lighting.

No cartoon appearance.
No generic AI aesthetic.
The motorcycle must remain physically believable and visually consistent throughout the entire film.

Use dramatic wide landscapes contrasted with intimate close-ups.

The color palette begins cold and desaturated and gradually transitions into rich, warm golden tones toward the final reveal.

MAIN CHARACTER

A strikingly beautiful adult woman in her late 20s.

Dark flowing hair naturally tucked beneath a premium black motorcycle helmet.

Confident, focused expression.

Natural makeup.

She wears a fitted black leather motorcycle jacket, dark riding pants, black gloves and realistic protective riding boots.

Her appearance, clothing, helmet and motorcycle remain perfectly consistent throughout the entire film.

She should look like a real professional rider, not a fashion model posing on a motorcycle.

MOTORCYCLE

A massive premium heavy motorcycle.

Muscular proportions.

Large engine.

Wide rear tire.

Heavy metallic frame.

Premium black and brushed-metal finishes.

Realistic suspension movement.

Visible engine vibration.

Powerful headlight.

Subtle reflections across the fuel tank.

The motorcycle should feel extremely powerful but elegant.

Keep the exact motorcycle design consistent throughout every shot.

SCENE 1 — THE UNKNOWN ROAD

0–5 SECONDS

EXTREME WIDE CINEMATIC SHOT.
