廢棄森林停車場裡載著驚恐司機的老舊綠色巴士，變形為巨大的機械機器人

提示詞

建立一段 30 秒超寫實電影級變形序列，場景設定在被茂密森林環繞的偏遠廢棄停車場。使用照片級視覺效果、寫實人體解剖結構、細緻機械紋理、自然光線、物理精確的變形、電影級運鏡、寫實陰影、大氣霧氣、細微膠卷顆粒感以及好萊塢等級的 VFX。

0–5 秒 — 巴士
一輛老舊、超長的美式綠色巴士停在被樹木環繞的破舊停車場中。一名年輕亞裔男性駕駛坐在車內，緊張地握著方向盤。巴士突然劇烈搖晃。駕駛驚恐地環顧四周，車內開始傳出奇怪的機械聲。

5–12 秒 — 變形開始
內部開始由內而外劇烈變形。座椅分裂並重新組合成複雜的機械零件。金屬面板扭曲、摺疊並滑動到位。駕駛艙重塑成巨大的機械頭部，擋風玻璃變成發光的眼睛，前保險桿形成威脅性的嘴部。

變形過程應感覺沉重、機械化且符合物理邏輯，活塞、齒輪、液壓系統、纜線和金屬板的移動需具備寫實的重量感。

12–18 秒 — 機械巨人現身
整輛巴士變形成一隻類似怪異毛毛蟲的巨大機械生物。輪子保持可見並作為其身體的一部分運作。嘴部兩側以液壓方式張開，露出由破損的橘色巴士扶手和金屬零件組成的尖銳牙齒。

生物劇烈搖晃並咆哮，煙霧、灰塵和碎片瀰漫空中。

18–24 秒 — 攻擊
機械生物向驚恐的駕駛猛撲過去。巨大的下顎戲劇性地咬向他（非血腥畫面），將他舉起並拋到背上。他抓住裸露的金屬扶手以防掉落，同時生物劇烈移動。

使用快速的電影級運鏡、寫實動態模糊、飛揚的灰塵和火花。

24–30 秒 — 最終揭露
機械生物在停車場和森林中快速爬行，將小型障礙物壓碎在巨大的身體下。其金屬腿部和輪子以令人信服的機械重量感移動。

鏡頭拉遠至戲劇性的廣角鏡頭，揭示生物相對於森林的巨大比例。

結尾定格在發光的機械眼和咆哮嘴部的震撼特寫。

視覺指導：超寫實、照片級 4K/8K 細節、寫實金屬、鏽跡、污垢、液壓活塞、齒輪、纜線和機械關節、物理精確的變形、寫實反射、電影級景深、大氣夜間照明、體積霧、動態運鏡、強烈的科幻驚悚氛圍。

重要：確保巴士、駕駛、環境和機械生物在整個過程中保持一致。變形必須看起來像真實的物理機器在變形，而非魔法或卡通效果。

Create a 30-second ultra-realistic cinematic transformation sequence set in a remote, abandoned parking area surrounded by dense forest. Use photorealistic visuals, realistic human anatomy, detailed mechanical textures, natural lighting, physically accurate transformations, cinematic camera movement, realistic shadows, atmospheric fog, subtle film grain, and Hollywood-level VFX.\n\n0–5 sec — The Bus\nAn old, oversized, extra-long American-style green bus sits abandoned in a dilapidated parking lot surrounded by trees. A young Asian male driver sits inside, nervously gripping the steering wheel. The bus suddenly shakes violently. The driver looks around in fear as strange mechanical sounds begin from inside the vehicle.\n\n5–12 sec — Transformation Begins\nThe interior starts aggressively transforming from the inside out. Seats split apart and reorganize into complex mechanical components. Metal panels twist, fold and slide into place. The driver's cabin reshapes into a massive mechanical head, while the windshield becomes glowing eyes and the front bumper forms a menacing mouth.\n\nThe transformation should feel heavy, mechanical and physically believable, with pistons, gears, hydraulic systems, cables and metal plates moving with realistic weight.\n\n12–18 sec — Mechanical Giant Emerges\nThe entire bus transforms into a gigantic mechanical creature resembling a monstrous caterpillar. The wheels remain visible and functional as part of its body. The sides of the mouth open hydraulically, revealing sharp teeth made from broken orange bus handrails and metal components.\n\nThe creature violently shakes and roars as smoke, dust and debris fill the air.\n\n18–24 sec — Attack\nThe mechanical creature lunges toward the terrified driver. Its enormous jaws snap around him in a dramatic but non-graphic attack, lifting and throwing him onto its back. He grabs onto the exposed metal handrails to avoid falling as the creature moves violently.\n\nUse fast cinematic camera movement, realistic motion blur, flying dust and sparks.\n\n24–30 sec — Final Reveal\nThe mechanical creature crawls rapidly through the parking lot and forest, crushing small obstacles beneath its massive body. Its metallic legs and wheels move with convincing mechanical weight.\n\nThe camera pulls far back into a dramatic wide shot, revealing the creature's enormous scale against the forest.\n\nEnd on a powerful close-up of its glowing mechanical eyes and roaring mouth.\n\nVisual Direction: Ultra-realistic, photorealistic 4K/8K detail, realistic metal, rust, dirt, hydraulic pistons, gears, cables and mechanical joints, physically accurate transformation, realistic reflections, cinematic depth of field, atmospheric night lighting, volumetric fog, dynamic camera movement, intense sci-fi thriller atmosphere.\n\nImportant: Keep the same bus, driver, environment and mechanical creature consistent throughout. The transformation must look like a real physical machine transforming, not magical or cartoon
