视频——一个连续的镜头：一只乌鸦飞过黑暗的小巷，用翅膀遮住镜头，然后乌鸦女孩登场

VIDEO — ONE CONTINUOUS CINEMATIC SHOT: A RAVEN FLIES THROUGH A DARK ALLEY, COVERS THE LENS WITH ITS WINGS, AND REVEALS THE RAVEN GIRL SCENE CONTEXT A real, narrow old-city alley at night after rain. The camera faces straight down the alley. A single raven flies from the distant end toward the camera. As it reaches the lens, it spreads both wings until real black feathers completely cover the frame. The shot passes through this natural feather occlusion and reveals the same alley with the raven girl now standing in the center. The same raven finishes by settling naturally on her shoulder. FORMAT One continuous shot, 15 seconds, 16:9 horizontal, 720p super-resolution, full live-action photorealism. Prestige gothic thriller, restrained low-saturation color grade, natural 35mm film texture. Diegetic sound only. No captions, no subtitles, no music, no logos, no watermark. ACTIVE REFERENCES @Image1 — RAVEN IDENTITY ONLY. Use the mature black raven's exact body proportions, heavy curved beak, dark intelligent eyes, realistic black feather structure, wedge-shaped tail, feet, and the small silver-gray shoulder feather as its continuity mark. TAKE NOTHING ELSE FROM @Image1: not the white background, not the three-view layout, not duplicated ravens, and not the studio lighting. All three views depict one and the same raven. Exactly one raven exists in the video. @Image2 — RAVEN GIRL IDENTITY AND WARDROBE ONLY. The close portrait and full-body view show one and the same adult woman. Preserve her established face, gray-blue eyes, long blue-black hair, black cropped wool jacket, dark high-neck blouse and scarf, wide black trousers, worn black boots, and restrained feather details. TAKE NOTHING ELSE FROM @Image2: not the gray studio background, not the split-screen layout, not duplicated women, not the studio pose, and not the flat studio lighting. Exactly one woman exists in the video. @Image3 — LOCATION, LIGHTING AND COLOR ONLY. Use the exact narrow alley structure, damp cobblestones, worn brick and plaster walls, drainpipes, recessed doors, deep layered darkness, one weak amber wall lamp, cold blue-gray night ambience, and very low saturation. TAKE NOTHING ELSE FROM @Image3: no frozen stillness, no extra architecture, no additional lamps, no brighter exposure, and no glossy mirror-like pavement. @Video1 — MOTION RHYTHM AND OCCLUSION TRANSITION ONLY. Use only its overall shot progression: an empty corridor-like space, a dark flying creature approaching the lens, wings filling the frame, and a person revealed after the full-frame occlusion. TAKE NOTHING ELSE FROM @Video1: no butterfly, no original woman, no hotel corridor, no player controls, no interface, no text, and no exact color grade. THE EIGHT MOST IMPORTANT RULES RULE ONE — ONE UNBROKEN FORWARD CAMERA MOVE. The camera performs one slow, restrained push forward along the alley axis from first frame to last. No orbit, no sideways tracking, no crane, no whip-pan, no sudden zoom, no reverse movement, and no cut. A faint controlled handheld breathing is acceptable, but there is no visible shake. IF THE CAMERA CUTS, ORBITS, MOVES SIDEWAYS, OR REVERSES DIRECTION, THE GENERATION IS WRONG. RULE TWO — EXACTLY ONE RAVEN AND ONE WOMAN. Only one raven flies toward camera. Only one woman appears after the occlusion. The reference sheet layouts must never be interpreted as multiple birds or multiple women. IF A SECOND RAVEN, SECOND WOMAN, DUPLICATED BODY, OR BACKGROUND PERSON APPEARS, THE GENERATION IS WRONG. RULE THREE — THE RAVEN FLIES WITH REAL BIRD PHYSICS. It approaches from the far center of the alley with believable weight, wing joints, downstroke and upstroke, air resistance, body inertia, and natural motion blur. It never floats, glides like a paper cutout, changes size suddenly, or flies backward. IF THE FLIGHT LOOKS WEIGHTLESS, RUBBERY, MECHANICAL, OR LIKE A CGI GAME CREATURE, THE GENERATION IS WRONG. RULE FOUR — BOTH WINGS MUST COMPLETELY COVER THE LENS. Near the camera, the raven spreads both wings symmetrically. Layered primary feathers move physically close to the lens until no alley remains visible. The frame becomes a brief, textured black feather occlusion—not smoke, liquid, particles, shadow fog, or a digital dissolve. IF THE WINGS DO NOT COVER 100% OF THE FRAME, OR THE TRANSITION USES MAGIC EFFECTS INSTEAD OF REAL FEATHERS, THE GENERATION IS WRONG. RULE FIVE — THE TRANSFORMATION HAPPENS ONLY INSIDE THE OCCLUSION. Do not show a half-bird half-human body, stretching limbs, melting anatomy, growing feathers, smoke morphing, particles, or a visible body transformation. While the lens is fully covered by feathers, the state changes. As the feathers clear, the raven girl is already fully human and standing in the same alley. IF A HYBRID BODY OR VISIBLE MORPHING PROCESS APPEARS, THE GENERATION IS WRONG. RULE SIX — THE GIRL MUST MATCH @Image2. After the reveal, preserve her established face, blue-black hair, black cropped jacket, dark blouse and scarf, wide black trousers, boots, body proportions, and restrained expression. She stands calmly and naturally, breathing slightly, looking just past the camera. No glamour posing, no runway walk, no exaggerated expression, no beauty-filter skin. IF HER FACE, HAIR COLOR, CLOTHING, OR BODY PROPORTIONS CHANGE, THE GENERATION IS WRONG. RULE SEVEN — THE SAME RAVEN ENDS ON HER SHOULDER. After the reveal, the same raven from @Image1 completes one short natural landing onto her shoulder. Its feet visibly make contact with the coat, the fabric depresses slightly under its weight, the wings fold, and it balances with a small body adjustment. It does not merge into her body and she does not grow wings. IF THE RAVEN DISAPPEARS, MULTIPLIES, MERGES WITH HER, HOVERS, OR FAILS TO MAKE PHYSICAL CONTACT, THE GENERATION IS WRONG. RULE EIGHT — EVERYTHING MUST LOOK PRACTICALLY FILMED. Real skin pores, natural facial asymmetry, real wet stone, porous brick, worn wool, physically layered feathers, restrained motion blur, subtle film grain, gentle halation around the single lamp, and soft highlight rolloff. The pavement is damp but mostly matte, with only narrow broken reflections. IF THE IMAGE LOOKS PLASTIC, OILY, OVER-SHARPENED, HDR, LIKE A GAME CUTSCENE, OR LIKE A GLOSSY AI RENDER, THE GENERATION IS WRONG. CAMERA AND COMPOSITION Eye-level camera at roughly 1.6 meters, looking down the alley with a 35mm vintage anamorphic feeling. Start in a wide establishing composition with the empty alley readable. Maintain one-point depth without perfect artificial symmetry. The slow push stays centered on the raven's flight path. During the final reveal, settle into a three-quarter to full-body view of the woman, centered slightly off-axis with the alley still visible around her. No Dutch angle. No extreme shallow focus: keep the raven readable in flight and the woman plus nearby alley texture legible after the reveal. ACTION TIMING — 15 SECONDS 0.0–2.5s — HELD ALLEY ESTABLISHMENT The real alley is empty. The camera begins a very slow forward push. The weak amber lamp and cold ambient night light remain constant. Small damp reflections sit still on the stones. A tiny raven silhouette becomes visible at the distant bend. END STATE: one raven is clearly identifiable at the far center; no person is present. 2.5–6.5s — RAVEN APPROACH The raven flies toward camera along the alley centerline. Its wingbeats have a measured rhythm and real weight. The bird grows gradually in frame through physical approach, never by digital scaling. The camera continues the same slow push. END STATE: the raven reaches close middle distance, centered and facing camera; the alley, wall lamp and exposure remain unchanged. 6.5–9.0s — FULL-FRAME WING OCCLUSION The raven reaches the lens and spreads both wings. Primary feathers pass close to camera from both sides and completely block every part of the alley. Hold a brief tactile darkness made only of layered black feathers and realistic motion blur. END STATE: 100% of the frame is naturally covered by black raven feathers; no environment, person, smoke, particles or light burst remains visible. 9.0–12.0s — HUMAN REVEAL The close feathers withdraw and pass out of the immediate foreground. In the unchanged alley, the raven girl from @Image2 is already standing where the flight path ended. She is fully human, dressed exactly as referenced, with no wings or bird anatomy. The camera completes its slow push and settles. She breathes once and fixes a controlled, wary gaze just past camera. END STATE: the woman is clearly visible in a stable three-quarter to full-body composition; she is the only person; the same alley and light direction remain continuous. 12.0–15.0s — RAVEN LANDING AND FINAL HOLD The same raven enters with one short controlled wingbeat and lands on her shoulder. Feet contact the coat, the shoulder and fabric react subtly, the wings fold, and the bird steadies. The woman makes only a slight physical adjustment under its weight and remains composed. Hold the final image long enough to read both identities. END STATE: exactly one woman stands still in the alley; exactly one raven rests on her shoulder with wings folded; both faces are readable; no other subject enters. PHYSICS The raven's body follows its wingbeats with subtle vertical oscillation and forward inertia. Primary feathers separate under air load and overlap again during recovery. The full-frame occlusion is caused by proximity to the lens, not by the raven becoming gigantic. Landing includes visible foot contact, weight transfer, a tiny coat compression, one balancing movement, then stillness. Hair and coat move only from displaced air and the bird's landing. Rainwater does not ripple without cause. LIGHTING AND COLOR Low-key night cinematography. Most foreground walls remain in rich layered near-black shadow with faint brick and plaster texture. One weak dirty-amber practical wall lamp provides the only warm highlight; cold blue-gray ambient light separates the raven and the woman's dark silhouette from the alley. Very low saturation. Constant exposure and white balance. No flicker, no brightening during transformation, no magical rim light, no neon, no strong teal-orange split. AUDIO Diegetic only: faint distant city night tone, damp alley air, realistic approaching wingbeats, one low rush of air as feathers pass the lens, then a quiet claw-and-wool contact sound at landing. No dialogue, no voice-over, no score, no background music. COUNT Exactly one alley, one raven, one woman, one continuous forward camera move, one complete feather occlusion, one shoulder landing, zero cuts, zero other people, zero additional birds, zero text overlays. BANS No butterfly. No hybrid bird-woman anatomy. No wings attached to the woman. No visible morphing body. No smoke transformation, liquid transformation, particle burst, magical glow, black ink, digital dissolve, flash transition, or teleportation effect. No extra raven, extra woman, extra limbs, deformed hands, duplicated face, or changing wardrobe. No white reference background, no gray studio background, no split-screen layout. No bright daylight, neon, glossy pavement, oily highlights, plastic skin, wax face, heavy beauty retouching, oversaturation, aggressive teal-orange grade, excessive bokeh, sharpened HDR, 3D-render look, game-cinematic look, anime, illustration, subtitles, captions, logos, watermark, music, player interface, phone or camera visible in frame. FINAL HARD LOCKS The lens must be completely covered by real raven wings before the woman appears. The transformation occurs only inside that full-frame feather occlusion. The final frame contains exactly the @Image2 woman and the same @Image1 raven resting physically on her shoulder in the unchanged @Image3 alley.

视频——一个连续的镜头：一只乌鸦飞过黑暗的小巷，用翅膀遮住镜头，然后乌鸦女孩登场 场景设定 一个真实的、狭窄的古城小巷，雨后的夜晚。镜头正对着小巷深处。一只乌鸦从巷子远端飞向镜头。当它抵达镜头时，张开双翼，直到真实的黑色羽毛完全覆盖画面。镜头穿过这种自然的羽毛遮挡，在同一条小巷中揭示乌鸦女孩现在正站在中央。同一只乌鸦最后自然地落在她的肩膀上收尾。 格式 一个连续镜头，15秒，16:9横向，720p超分辨率，全实景真人照片级真实感。高级哥特惊悚风格，克制的低饱和度调色，自然35毫米胶片质感。仅使用场景内声音。无字幕、无说明文字、无音乐、无标志、无水印。 有效参考 @Image1 — 仅乌鸦身份。 使用成熟黑乌鸦的精确身体比例、粗重的弯喙、深色灵动的眼睛、逼真的黑色羽毛结构、楔形尾羽、脚爪，以及小片银灰色肩羽作为其连续性标记。 不要从@Image1取其他任何东西：不要白色背景、不要三视图布局、不要复制的乌鸦、不要影棚灯光。三个视图描绘的是同一只乌鸦。视频中只能存在一只乌鸦。 @Image2 — 仅乌鸦女孩的身份和服装。 特写肖像和全身视图展示的是同一位成年女性。保留她已确立的面容、灰蓝色眼睛、长长的蓝黑色头发、黑色短款羊毛外套、深色高领衬衫和围巾、宽大的黑色长裤、做旧的黑色靴子，以及克制的羽毛细节。 不要从@Image2取其他任何东西：不要灰色影棚背景、不要分屏布局、不要复制的女性、不要影棚姿势、不要平坦的影棚灯光。视频中只能存在一位女性。 @Image3 — 仅场景、灯光和颜色。 使用完全相同的小巷结构、潮湿的鹅卵石、斑驳的砖墙和灰泥墙壁、排水管、内嵌式门扇、深层递进的黑暗、一盏微弱的琥珀色壁灯、冷蓝灰色的夜晚环境光，以及极低的饱和度。 不要从@Image3取其他任何东西：不要冻结的静止感、不要额外的建筑、不要额外的灯、不要更亮的曝光、不要光滑如镜的路面。 @Video1 — 仅运动节奏和遮挡过渡。 仅使用其整体镜头进程：空旷的走廊式空间、一只深色的飞行生物飞向镜头、双翼填满画面、完全遮挡后揭示人物。 不要从@Video1取其他任何东西：不要蝴蝶、不要原始女性、不要酒店走廊、不要玩家控制、不要界面、不要文字、不要确切的调色风格。 最重要的八条规则 规则一——一次不间断的向前镜头移动。 镜头从小巷轴线方向，从第一帧到最后一帧执行一次缓慢、克制的向前推进。无环绕、无横向跟踪、无摇臂、无甩摇、无突然推拉、无反向运动、无剪辑。可以接受轻微受控的手持呼吸感，但没有可见的抖动。 如果镜头剪辑、环绕、横向移动或反向移动，则生成错误。 规则二——只有一只乌鸦和一个女人。 只有一只乌鸦飞向镜头。遮挡之后只出现一个女人。参考表布局绝不能被解读为多只鸟或多个女性。 如果出现第二只乌鸦、第二个女人、重复的身体或背景人物，则生成错误。 规则三——乌鸦以真实的鸟类物理方式飞行。 它从小巷远端中心靠近，具有可信的重量、翅膀关节、下行和上行拍翅、气阻、身体惯性以及自然的运动模糊。它绝不漂浮、不像纸片般滑行、不突然改变大小、也不向后飞。 如果飞行看起来失重、橡胶感、机械感或像CGI游戏生物，则生成错误。 规则四——双翼必须完全遮住镜头。 靠近镜头时，乌鸦对称地张开双翼。分层的初级飞羽从两侧物理上贴近镜头，直到小巷完全不可见。画面变成一个短暂的、有质感的黑色羽毛遮挡——不是烟雾、液体、粒子、阴影雾气或数字溶解。 如果双翼未覆盖画面的100%，或者过渡使用了魔法效果而非真实羽毛，则生成错误。 规则五——变形只发生在遮挡内部。 不要展示半鸟半人的身体、拉长的肢体、融化的解剖结构、生长羽毛、烟雾变形、粒子或可见的身体变形。在镜头被羽毛完全覆盖期间，状态发生变化。当羽毛消散时，乌鸦女孩已经完全是人形，并站立在同一条小巷中。 如果出现混合生物身体或可见的变形过程，则生成错误。 规则六——女孩必须与@Image2一致。 揭示后，保留她已确立的面容、蓝黑色头发、黑色短款外套、深色衬衫和围巾、宽大的黑色长裤、靴子、身体比例以及克制的表情。她平静自然地站立，轻轻呼吸，目光略过镜头。没有魅力摆姿，没有T台走步，没有夸张的表情，没有美颜滤镜的皮肤。 如果她的面容、发色、服装或身体比例发生变化，则生成错误。 规则七——同一只乌鸦最终落在她的肩膀上。 揭示后，@Image1中的同一只乌鸦完成一次短暂自然的降落到她的肩膀上。它的脚爪明显接触到外套，面料在其重量下轻微凹陷，双翼折叠，并通过小幅身体调整取得平衡。它不会融入她的身体，她也不会长出翅膀。 如果乌鸦消失、增殖、与她融合、悬停或未能发生物理接触，则生成错误。 规则八——所有内容必须看起来是实景拍摄的。 真实的皮肤毛孔、自然的面部不对称、真实的湿润石材、多孔的砖、做旧的羊毛、物理分层的羽毛、克制的运动模糊、细微的胶片颗粒、单灯周围的柔和光晕以及柔和的高光过渡。路面潮湿但大部分是哑光的，只有狭窄断裂的反光。 如果画面看起来是塑料感、油腻感、过锐、HDR、游戏过场动画或光滑的AI渲染，则生成错误。 镜头与构图 与眼睛齐平的镜头，约1.6米高度，使用35毫米复古变形宽银幕感向下看小巷。以可读的宽阔建立性空巷构图开始。保持一点透视深度，但不要完美的人工对称。缓慢的推进始终居中对准乌鸦的飞行路径。在最终揭示时，切换到女性的三分之二到全身视图，略微偏离轴线居中，小巷仍然可见地环绕在她周围。无荷兰角。无极度浅焦：飞行中的乌鸦要清晰可读，揭示后的女性和附近的小巷质感也要清晰可读。 动作时序——15秒 0.0–2.5秒——小巷建立保持 真实的小巷是空的。镜头开始非常缓慢的向前推进。微弱的琥珀色壁灯和冷色环境夜光保持不变。石头上的小水洼倒影静止不动。一个微小的乌鸦剪影出现在远处的拐弯处。 结束状态：一只乌鸦清晰可辨地位于远处中心；没有人出现。 2.5–6.5秒——乌鸦接近 乌鸦沿小巷中线飞向镜头。它的拍翅有稳定的节奏和真实的重量。鸟通过物理接近在画面中逐渐变大，绝不通过数字缩放。镜头继续相同的缓慢推进。 结束状态：乌鸦到达近中距离，居中并面向镜头；小巷、壁灯和曝光保持不变。 6.5–9.0秒——全画面翅膀遮挡 乌鸦抵达镜头并张开双翼。初级飞羽从两侧贴近镜头，完全挡住小巷的每一个部分。保持短暂的触觉黑暗，仅由分层的黑色羽毛和真实的运动模糊构成。 结束状态：画面的100%被自然地覆盖上黑色乌鸦羽毛；没有环境、人物、烟雾、粒子或光晕残留可见。 9.0–12.0秒——人物揭示 贴近的羽毛退出，移出近景。在未变的小巷中，来自@Image2的乌鸦女孩已经站在飞行路径结束的地方。她完全是人类，服装与参考完全一致，没有翅膀或鸟类解剖结构。镜头完成缓慢的推进并稳定下来。她呼吸一次，将克制的、警惕的目光锁定在镜头略偏的位置。 结束状态：女性在稳定的三分之二到全身构图中清晰可见；她是唯一的人物；同一条小巷和光线方向保持连续。 12.0–15.0秒——乌鸦降落与最终保持 同一只乌鸦以一次短暂受控的拍翅进入并降落在她的肩膀上。脚爪接触外套，肩膀和面料微妙地反应，双翼折叠，鸟稳住。女性仅在其重量下做出轻微的物理调整，并保持从容。保持最终画面足够长时间以读出两个身份。 结束状态：恰有一位女性静立于小巷中；恰有一只乌鸦以折叠的双翼停在她肩膀上；两张面孔都清晰可读；没有其他主体进入。 物理 乌鸦的身体跟随其拍翅，具有微妙的垂直摆动和前向惯性。初级飞羽在气流负荷下分开，在恢复时再次重叠。全画面遮挡是由接近镜头造成的，而不是乌鸦变得巨大。降落包括可见的脚爪接触、重量转移、微小的外套压缩、一次平衡动作，然后静止。头发和外套仅因排出的空气和鸟的降落而移动。雨水在没有原因的情况下不起涟漪。 灯光与色彩 低调夜景摄影。大部分前景墙壁保持丰富的、层次分明的近黑色阴影，带有微弱的砖和灰泥质感。一盏微弱的脏琥珀色实用壁灯提供唯一的暖色高光；冷蓝灰色环境光将乌鸦和女性的深色轮廓从小巷中分离出来。极低的饱和度。恒定的曝光和白平衡。无闪烁，变形期间不变亮，无魔幻边缘光，无霓虹，无强烈的青橙分离。 音频 仅场景内声音：微弱的远处城市夜间音调，潮湿的小巷空气，真实的接近拍翅声，羽毛经过镜头时的一阵低气流声，然后是降落时安静的爪子和羊毛接触声。无对话、无旁白、无配乐、无背景音乐。 计数 恰有一条小巷、一只乌鸦、一个女人、一次连续的前向镜头移动、一次完整的羽毛遮挡、一次肩膀降落，零剪辑，零其他人，零额外的鸟，零文字叠加。 禁止项 无蝴蝶。无混合鸟人解剖结构。女性身上无附着的翅膀。无可见的变形身体。无烟雾变形、液体变形、粒子爆发、魔幻光辉、黑色墨迹、数字溶解、闪光过渡或传送效果。无额外的乌鸦、额外的女人、额外的肢体、畸形的手、重复的面容或变化的服装。无白色参考背景，无灰色影棚背景，无分屏布局。无明亮的日光、霓虹、光滑的路面、油腻的高光、塑料般的皮肤、蜡像般的面孔、重度美颜、过度饱和、强烈的青橙调色、过度的散景、过锐的HDR、3D渲染外观、游戏过场动画外观、动漫、插画、字幕、说明文字、标志、水印、音乐、播放器界面，画面中无手机或相机可见。 最终硬性锁定 在女人出现之前，镜头必须完全被真实的乌鸦翅膀覆盖。变形只发生在该全画面羽毛遮挡之内。最终画面只包含@Image2的女性和同一只@Image1乌鸦，物理地停在她的肩膀上，位于未变的@Image3小巷中。
