制作一个45秒的超写实电影级科幻惊悚/动作片段，视觉品质对标高预算好莱坞大片。

Create a 45-second ultra-photorealistic cinematic sci-fi thriller/action sequence with the visual quality of a high-budget Hollywood blockbuster. CONCEPT In a futuristic megacity at night, a mysterious global emergency signal orders humanity to evacuate Earth immediately. A lone 25-year-old female survivor races toward an orbital evacuation station while millions flee the city. Everyone believes a catastrophic disaster is approaching, but the truth is far more terrifying: something enormous has entered Earth's orbit, and humanity was never the one being evacuated. MAIN CHARACTER A beautiful young adult female survivor, approximately 25 years old, with a natural oval face, expressive brown eyes, realistic skin texture, subtle facial imperfections and long slightly messy dark-brown hair. She wears dark charcoal futuristic tactical clothing, lightweight armor, gloves, utility belt, dark pants and rugged combat boots. She carries a compact futuristic rifle and blue-white handheld scanner. Maintain perfect facial identity, hairstyle, body proportions, clothing, weapon and scanner throughout the video. ENVIRONMENT A massive futuristic megacity during a violent nighttime storm, filled with towering skyscrapers, holographic emergency warnings, wet streets, abandoned vehicles, evacuation towers, military aircraft, orbital elevators, smoke, steam, rain and flashing red emergency lights. The atmosphere should feel chaotic, enormous and realistic. 0–5 SECONDS — THE WARNING Begin with a huge aerial shot of the futuristic city. Every screen suddenly displays: "GLOBAL EVACUATION — LEAVE EARTH IMMEDIATELY." Sirens erupt as crowds panic and spacecraft launch. The female survivor stands in the rain, looking at her scanner as it detects an enormous unidentified object approaching Earth. 5–10 SECONDS — THE EVACUATION She runs toward a massive orbital evacuation station through terrified crowds. Military spacecraft launch overhead. Emergency countdowns flash across buildings. Her scanner begins malfunctioning as a strange blue glow spreads across the clouds. 10–15 SECONDS — SOMETHING ARRIVES She reaches an elevated platform and looks upward. The clouds slowly open, revealing an impossibly enormous alien structure emerging from orbit. It is far larger than any human spacecraft, with gigantic geometric surfaces and thousands of blue-white lights. The Moon appears tiny beside it. 15–20 SECONDS — THE REVELATION The entire city falls silent. The colossal structure moves closer without visible propulsion. Every aircraft stops. Her scanner suddenly receives a transmission from the object. Every screen on Earth turns black. 20–25 SECONDS — THE MESSAGE Every screen simultaneously displays the same mysterious alien symbol. A calm distorted voice comes through her scanner: "Earth evacuation confirmed." She looks around in confusion as humanity realizes the message did not come from human authorities. 25–30 SECONDS — THE SKY OPENS The enormous structure positions itself around Earth instead of attacking. Thousands of blue-white lights activate across its surface. Massive beams descend toward the planet, scanning cities, oceans and continents. No explosions. No weapons fire. 30–35 SECONDS — THE HIDDEN SIGNALS Her scanner suddenly reveals thousands of mysterious signals beneath Earth's surface. The signals exist beneath oceans, mountains and cities, forming a gigantic planetary network. She realizes the structure is searching for something that has been hidden on Earth for thousands of years. 35–40 SECONDS — THE TRUTH A powerful blue-white pulse surrounds the planet. She experiences a brief vision of ancient Earth, where enormous alien structures already existed beneath the surface. The vision disappears. Her scanner displays: "SUBJECT LOCATED." 40–45 SECONDS — FINAL CLIFFHANGER The camera rapidly pulls away from the city and rises into orbit. Reveal Earth surrounded by the enormous alien structure. Hundreds of additional unidentified spacecraft suddenly appear behind it, silently filling the sky. Cut back to the survivor staring upward in terror. Her scanner activates one final time. The voice whispers: "You were never the ones being evacuated." CUT TO BLACK. CINEMATOGRAPHY Professional Hollywood science-fiction cinematography using massive aerial shots, atmospheric tracking, handheld evacuation footage, extreme close-ups, macro technology shots, low-angle perspectives, dynamic tracking and dramatic orbital-scale pull-outs. Camera movement must feel physically motivated and cinematic. VISUAL STYLE Ultra-photorealistic live-action, 4K HDR, realistic human skin, detailed futuristic architecture, realistic spacecraft, wet reflective surfaces, rain, fog, smoke, steam, dust, natural motion blur, cinematic depth of field, subtle film grain and anamorphic lens characteristics. LIGHTING Dark nighttime atmosphere with cold blue ambient light, red emergency lighting, lightning, blue-white alien illumination, volumetric beams, wet reflections, deep shadows and realistic light falloff. REALISM Realistic human movement, crowds, aircraft, spacecraft, rain and environmental physics. The alien structure must feel unimaginably massive, physically believable and extremely slow-moving. No weightless objects or artificial-looking CGI. CONTINUITY Maintain identical female character identity, face, hair, clothing, weapon, scanner, city, spacecraft and alien structure throughout the sequence. No morphing, redesigns, outfit changes or inconsistent scale. NEGATIVE PROMPT No cartoon, anime, video-game graphics, plastic CGI, unrealistic physics, gore, blood, distorted faces, extra fingers, extra limbs, character morphing, outfit changes, creature redesigns, random explosions, excessive lens effects, flickering objects, teleportation, floating debris or unrealistic lighting.

制作一个45秒的超写实电影级科幻惊悚/动作片段，视觉品质对标高预算好莱坞大片。 概念 在夜晚的未来巨型都市中，一道神秘的全球紧急信号命令人类立即撤离地球。一名独自行动的25岁女性幸存者在数百万人逃离城市的同时，朝一座轨道撤离站飞奔。所有人都相信一场灾难性浩劫即将降临，但真相远比这更恐怖：一个无比巨大的物体已进入地球轨道，而人类从来都不是被撤离的对象。 主要角色 一位美丽、约25岁的年轻成年女性幸存者，拥有自然的鹅蛋脸、深邃的棕色眼睛、真实的皮肤质感、细微的面部瑕疵，以及一头略为凌乱的长深棕色头发。她身穿深炭灰色未来风战术服、轻型护甲、手套、战术腰带、深色长裤和坚固的战斗靴。她携带一把紧凑型未来风步枪和一个蓝白色手持扫描仪。在整个视频中保持完美一致的面部形象、发型、身材比例、服装、武器和扫描仪。 环境 暴风雨夜晚的巨型未来都市，遍布高耸的摩天大楼、全息紧急警报、湿润的街道、被遗弃的车辆、撤离塔、军用飞行器、轨道电梯、烟雾、蒸汽、雨水和闪烁的红色应急灯。氛围应显得混乱、宏大且真实。 0–5秒 —— 警告 以未来城市的巨大航拍镜头开场。每块屏幕突然显示："GLOBAL EVACUATION — LEAVE EARTH IMMEDIATELY."（全球撤离——立即离开地球）。警报声骤然响起，人群陷入恐慌，航天器升空。女性幸存者站在雨中，查看她的扫描仪，扫描仪探测到一个巨大的不明物体正在接近地球。 5–10秒 —— 撤离 她穿过惊恐的人群，朝一座巨大的轨道撤离站跑去。军用航天器从头顶发射。应急倒计时在建筑间闪烁。她的扫描仪开始失灵，奇怪的蓝色辉光在云层中蔓延。 10–15秒 —— 某种东西到来 她抵达一处高架平台，抬头仰望。云层缓缓裂开，露出一个从轨道中出现、不可思议地巨大的外星结构。它比任何人类航天器都庞大，拥有巨大的几何表面和数千盏蓝白色灯光。月球在它旁边显得渺小。 15–20秒 —— 真相揭晓 整座城市陷入寂静。巨型结构在没有可见推进力的情况下继续靠近。每一架飞行器都停了下来。她的扫描仪突然接收到来自该物体的传输信号。地球上的每一块屏幕都熄灭变黑。 20–25秒 —— 讯息 所有屏幕同时显示同一个神秘的外星符号。一个平静而扭曲的声音从她的扫描仪中传出："Earth evacuation confirmed."（地球撤离已确认）。她困惑地环顾四周，人类意识到这条讯息并非来自人类当局。 25–30秒 —— 天空开启 巨型结构没有发动攻击，而是环绕地球定位。数千盏蓝白色灯光在其表面亮起。巨大的光束朝行星下降，扫描城市、海洋和大陆。没有爆炸。没有武器开火。 30–35秒 —— 隐藏的信号 她的扫描仪突然揭示出地球表面之下有数千个神秘信号。这些信号存在于海洋、山脉和城市之下，构成一个庞大的行星网络。她意识到该结构正在搜索某样在地球上隐藏了数千年的东西。 35–40秒 —— 真相 一道强大的蓝白色脉冲环绕地球。她短暂地体验到古代地球的幻象，看到地表之下早已存在的巨型外星结构。幻象消失。她的扫描仪显示："SUBJECT LOCATED."（目标已定位）。 40–45秒 —— 最终悬念 镜头从城市迅速拉开，升至轨道。揭示地球被巨型外星结构包围。在其后方突然出现数百个额外的未知航天器，无声地布满天空。切回幸存者，她恐惧地仰望天空。她的扫描仪最后一次启动。声音低语："You were never the ones being evacuated."（你们从来都不是被撤离的对象）。切黑。 摄影 专业的好莱坞科幻摄影手法，使用大规模航拍、氛围跟拍、手持撤离镜头、极近特写、宏观科技镜头、低角度视角、动态跟踪和戏剧性的轨道尺度拉出。镜头运动必须具有物理动机并具有电影感。 视觉风格 超写实真人电影，4K HDR，真实的人类皮肤，精细的未来建筑，真实的航天器，湿润的反射表面，雨、雾、烟、蒸汽、灰尘，自然动态模糊，电影级景深，微妙胶片颗粒和变形镜头特征。 灯光 夜间昏暗氛围，冷蓝色环境光，红色应急照明，闪电，蓝白色外星光源，体积光束，湿润反射，深邃阴影和真实的光线衰减。 真实感 真实的人类动作、人群、飞行器、航天器、雨水和环境物理。外星结构必须感觉不可思议地巨大、物理可信、极其缓慢移动。没有失重物体或看起来不真实的CGI。 连续性 在整个片段中保持一致的女性角色身份、面容、头发、服装、武器、扫描仪、城市、航天器和外星结构。不变形、不重新设计、不更换服装、不出现比例不一致。 负面提示 不要卡通、动漫、电子游戏画面、塑料感CGI、不真实物理、暴力血腥、面部扭曲、多余手指、多余肢体、角色变形、更换服装、生物重设计、随机爆炸、过度镜头效果、物体闪烁、瞬移、漂浮碎片或不真实灯光。
