使用 @image1 到 @image4，製作一支寫實風格、12 秒、9:16 直式的時尚短片：一位【4 歲女孩】（身高約【110 公分】）依序穿上四套不同的服裝。

參考圖
@image1、@image2、@image3、@image4 都是同一位真實的【4 歲女孩】。每一套服裝裡，她的臉、膚色和身體比例都要完全一致。她的髮型和頭飾會隨服裝改變，必須跟每張參考圖一樣。
@image1 → 第 1 套：【深海軍藍長洋裝，喇叭袖、蓬裙長及腳踝，裡面穿同布料的海軍藍安全褲；大紅色蝴蝶結髮飾、黑色瑪莉珍鞋，一支稻草編的魔女掃帚是她的道具。】
@image2 → 第 2 套：【黑色長洋裝，搭配及地的黑色披風和紫黑色羽毛領；頭上一對又大又彎、有光澤的黑色角；黑靴，手拿高高的黑色權杖。】
@image3 → 第 3 套：【冰藍色洋裝，土耳其藍亮片上身、冰藍長袖、綴有小雪花的淺藍紗裙，身後一件閃亮長披風，銀色鞋子；她自己的深色長髮自然放下。】
@image4 → 第 4 套：【薰衣草紫公主洋裝，亮片綁帶上身、泡泡袖，一頂小銀色皇冠，一條很長的金色辮子垂在一側肩前，銀粉色鞋子。】
每張參考圖裡的服裝、顏色、材質、鞋子、頭飾和道具都要完全照做。參考圖只用來決定女孩的長相和服裝；房間和動作照下面的描述來做。

木頭吊扇（最重要的畫面元素）
吊扇裝在離鏡頭極近的地方，所以看起來非常巨大，而且被畫面裁切：圓形的拉絲金屬馬達外殼在畫面上方正中間，有一部分被切掉；三片寬大的胡桃木扇葉長到尖端永遠在畫面外。木頭色調溫暖、有真實木紋，因為離鏡頭太近而有點失焦；每片扇葉都是實心、不透明的。一開始吊扇是靜止的；女孩按下遙控器後，吊扇順時針轉動，所以每片扇葉都從畫面右側進來、從左側離開。
扇葉轉到畫面正中央時，會蓋住幾乎整個畫面，大約 80% 到 90%，讓女孩和她的整套服裝完全被遮住：任何洋裝、裙子、披風、拖尾、袖子、手、腳、鞋子、頭髮、頭飾或道具，都不能在任何地方露出來；畫面左邊只露出一點【黃色】沙發，右邊只露出一點地毯。扇葉經過是換裝的唯一方式。

場景
木地板上鋪著一塊【象牙白的北歐風地毯，上面有黑色小方點】。一張長長的弧形【奶油黃（淡黃色，不是粉紅、不是蜜桃色）】沙發露出一部分，被畫面左邊裁切。上面描述的木頭吊扇位在鏡頭和地毯之間，非常靠近鏡頭。

鏡頭與構圖
一個連續鏡頭。鏡頭完全不動，以精準的 90 度垂直朝下，越過吊扇看向地毯上的女孩。從第一格到最後一格，構圖完全相同。女孩躺在沙發旁的地毯上，頭朝畫面上方、腳朝下方。落地之後她的位置固定：頭頂約在畫面高度三分之一處，腳約在五分之四處，左右置中。四套服裝都維持同一個位置和大小，不會在畫面裡上下滑動。每一套的洋裝、裙子和披風都整齊地貼著她的身體擺放：都在畫面寬度中間的一半以內，不會往左右兩邊攤開。

時間與動作
0.0–1.5 秒：女孩穿著第 1 套，【大紅蝴蝶結】清楚地戴在頭頂，兩手空空地整個人躺在【黃色】沙發上，全身由沙發座墊撐著。【稻草掃帚】一開始就放在地毯上，在她會落下的位置的右邊。第一格開始，她就馬上在沙發座墊上翻身成趴著，接著繼續往畫面右側滾，從沙發邊緣滾下來，輕輕仰躺落在地毯上，頭朝畫面上方。滾的時候兩腿併攏，洋裝全程貼著腿。躺好之後，她的兩腿伸直、自然併攏，不張開，第 1 套期間一直維持這樣。她的長洋裝自然維持原位：裙子停在腿邊，裙擺不會高過膝蓋。【掃帚】放在她身旁很近的地毯上。
1.0–2.4 秒：一隻有著圓滾滾大眼睛的【小黑貓】，從畫面左上方的沙發跳下來，沿著她頭頂上方的地毯從畫面左邊走到右邊，蜷縮在她的左臉頰旁（也就是畫面右側、跟遙控器相反的那一邊）。接著【小黑貓】抬起頭，用圓滾滾的大眼睛直直往上看著鏡頭，一直待到第一片扇葉經過。
1.5–2.6 秒：她從右手邊的地毯上拿起一個白色小遙控器，直直朝上對準吊扇，用拇指按一下按鈕，再把遙控器放回身旁的地毯上。
2.6–3.2 秒：吊扇開始轉動。第一片寬大的扇葉掃過她，在扇葉經過的中間點，把她的整套服裝、【掃帚】和【貓】都遮住。扇葉後緣一過去，第 2 套就完整出現，【紅蝴蝶結】、【黑貓】和【掃帚】都不見了。
3.2–5.6 秒：第 2 套。她躺在同一個位置，【把高高的黑色權杖斜放在身前，對鏡頭露出一個淺淺的、帶點狡黠的微笑，臉部放鬆自然。頭上那對又大又彎的黑角，全程清楚地出現在她頭頂上方的地毯上。】
5.6–6.1 秒：下一片扇葉經過，露出第 3 套。
6.1–8.3 秒：第 3 套。她躺在同一個位置，【舉起一隻手，手掌張開朝向鏡頭，輕輕揮幾下，像在打招呼，同時溫柔地微笑，直視鏡頭。】
8.3–8.8 秒：下一片扇葉經過，露出第 4 套。
8.8–12.0 秒：第 4 套。她躺在同一個位置，【雙手在胸前握著長長金色辮子的尾端，慢慢對著鏡頭微笑。】這個姿勢一直維持到最後一格，讓最後一套服裝清楚可見。

換裝規則
剛好四套服裝、剛好三次換裝。每次換裝都由經過的木頭扇葉遮住；每次扇葉經過的中間點，扇葉要蓋住畫面約 80% 到 90%，把她和她的整套服裝都遮住，兩者都完全看不到。扇葉蓋住之前，目前這套服裝維持不變；扇葉後緣經過她的那一刻，新服裝和新姿勢就已經完成。不使用其他任何轉場方式。

光線
柔和溫暖的雜誌風光線，色溫約 4000K，一道柔和的斜向窗光灑在地毯上。女孩身上的光線均勻，她和沙發底下有柔和、一致的接觸陰影。

必須保持一致
一個連續鏡頭，不剪接。房間、地毯、沙發、吊扇和鏡頭都不改變。四套服裝都是同一張臉，表情自然含蓄：溫柔的微笑，絕不誇張、不咧太開。影片裡只有一個人物；唯一的動物是【黑貓】，而且只出現在第 1 套。【紅蝴蝶結】、【黑貓】和【掃帚】只屬於第 1 套：第 1 套期間三者都清楚可見，第 2、3、4 套都不出現。動作要符合【4 歲女孩】的自然樣子，身體結構寫實，布料動態可信。她的服裝始終端莊、維持原位：每件洋裝和裙子的下擺全程都在膝蓋或更長，不會翻起或跑到膝蓋以上。除了【掃帚】、遙控器和【權杖】，沒有其他道具。第一片扇葉經過後，【黑貓】和【掃帚】不再出現。不要任何魔法效果：沒有閃光、雪花、冰、發光、煙霧或粒子。不要文字、字幕、標誌或浮水印。

Using @image1 through @image4, create a photorealistic, 12-second vertical 9:16 fashion video of one 【4-year-old girl】 (about 【110 cm】 tall) wearing four different costumes, one after another.

Reference images
@image1, @image2, @image3 and @image4 all show the same real 【4-year-old girl】. Keep her face, skin tone and body proportions exactly the same in every outfit. Her hairstyle and headpiece change with each outfit and must match each reference image.
@image1 → Outfit 1: 【long dark navy dress with bell sleeves and a full skirt reaching down to her ankles, with matching navy shorts in the same fabric worn underneath, a big red hair bow, black Mary Jane shoes, with a straw witch's broom as her prop.】
@image2 → Outfit 2: 【long black dress and floor-length black cape with a purple-black feather collar, two large curved glossy black horns on her head, black boots, holding a tall black staff.】
@image3 → Outfit 3: 【ice-blue dress with a turquoise sequin bodice, long ice-blue sleeves and a pale-blue tulle skirt with small snowflakes, a long glittery cape behind her, silver shoes; her own long dark hair worn down.】
@image4 → Outfit 4: 【lavender princess dress with a sequin lace-up bodice and puff sleeves, a small silver tiara, a very long golden-blonde braid over one shoulder, silver-pink shoes.】
Reproduce the clothing, colours, materials, shoes, headpieces and props of each reference image exactly. Use the reference images only for the girl's identity and outfits; build the room and the actions from the description below.

Wooden ceiling fan (the most important visual element)
The fan is mounted extremely close to the camera lens, so it looks gigantic and is cropped by the frame: its round brushed-metal motor housing is partly cut off at the top centre, and its three broad walnut blades are so long that their tips are always outside the frame. Warm wood with real grain, slightly out of focus because it is so close to the lens; every blade is solid and opaque. The fan is still at first; after the girl presses the remote, it turns clockwise, so each blade comes in from the right side of the frame and leaves on the left side.
When a blade reaches the centre of the frame, it covers almost the entire picture — about 80 to 90 percent of the frame — so the girl and her entire outfit are completely hidden: no part of any dress, skirt, cape, train, sleeve, hand, foot, shoe, hair, headpiece or prop shows anywhere; only a little of the 【yellow】 sofa at the left edge of the frame and a little of the rug at the right edge still show. The passing blades are the only way the outfits change.

Scene
【An ivory Scandinavian-style rug with small black square dots】 lies on a wooden floor. A long, curved sofa in 【soft butter-yellow (pale yellow — not pink, not peach)】 is partially visible, cropped along the left edge of the frame. The wooden ceiling fan described above is between the camera and the rug, very close to the camera.

Camera and composition
One single continuous shot. The camera is completely stationary, pointing straight down at an exact 90-degree angle, looking down past the ceiling fan at the girl on the rug. Exactly the same framing from the first frame to the last. The girl lies on the rug beside the sofa with her head toward the top of the frame and her feet toward the bottom. After she lands, her position is locked: the top of her head is about one third of the way down the frame and her feet are about four fifths of the way down, in the horizontal centre. She stays at exactly this spot and size in all four outfits and never slides up or down the frame. In every outfit, the dress, skirt and cape lie neatly close around her body: they stay within the middle half of the frame width and never fan out toward the left or right edges.

Timing and actions
0.0–1.5 s: The girl, wearing Outfit 1 — with the 【big red hair bow】 clearly on top of her head — lies fully on the 【yellow】 sofa with empty hands, with her entire body supported by the sofa cushion. The 【straw broom】 is already lying on the rug just to the right of the spot where she will land. Right from the first frame she turns over onto her stomach on the sofa cushion, then keeps rolling toward the right side of the frame, rolls off the edge of the sofa and lands softly on her back on the rug, head toward the top of the frame. Her legs stay close together while she rolls, and her dress stays down around her legs the whole time. As she settles, her legs lie straight and naturally close together, not spread apart, and stay that way for the rest of Outfit 1. Her long dress simply stays in place: the skirt stays down around her legs, and its hem never goes above her knees. The 【broom】 lies on the rug close beside her.
1.0–2.4 s: A 【small black cat】 with big round eyes jumps down from the sofa at the upper left of the frame, walks across the rug just above her head from the left of the frame to the right, and curls up close beside her left cheek — on the right side of the frame, opposite the remote control. Then the 【cat】 lifts its head and looks straight up into the lens with its big round eyes, staying there until the first blade pass.
1.5–2.6 s: She picks up a small white remote control from the rug on her right, points it straight up at the fan and presses the button once with her thumb, then lets the remote rest on the rug beside her.
2.6–3.2 s: The fan starts turning. The first broad blade sweeps across her, hiding her whole outfit, the 【broom】 and the 【cat】 at the middle of the pass. When its trailing edge has passed, Outfit 2 is fully revealed — and the 【red hair bow】, the 【black cat】 and the 【broom】 are gone.
3.2–5.6 s: Outfit 2. Lying in the same spot, 【she holds the tall black staff diagonally across her body and gives the lens a small, sly smile with a relaxed, natural face. The two large curved black horns on her head are clearly visible on the rug above her head the whole time.】
5.6–6.1 s: The next blade passes and reveals Outfit 3.
6.1–8.3 s: Outfit 3. Lying in the same spot, 【she raises one hand with her open palm facing the lens and gently waves it a few times, as if saying hello, smiling softly and looking straight into the lens.】
8.3–8.8 s: The next blade passes and reveals Outfit 4.
8.8–12.0 s: Outfit 4. Lying in the same spot, 【she holds the end of her long golden braid with both hands on her chest and slowly smiles into the lens.】 She holds this pose until the last frame so the final outfit stays clearly visible.

Transition rules
Exactly four outfits and exactly three outfit changes. Every change is hidden by a passing wooden fan blade; at the middle of each pass the blade covers about 80 to 90 percent of the frame, hiding her and her entire outfit, and nothing of either is visible. The current outfit stays unchanged until the blade covers it; the new outfit and the new pose are complete the moment the blade's trailing edge has passed her. No other transition method.

Lighting
Soft, warm editorial light around 4000K with a gentle diagonal beam of window light across the rug. Even light on the girl, soft consistent contact shadows under her and the sofa.

Must stay consistent
One continuous shot, no cuts. The room, rug, sofa, fan and camera never change. The same face in all four outfits, with natural, subtle expressions — gentle smiles, never exaggerated or overly wide. Only one person in the video; the only animal is the 【black cat】, and only during Outfit 1. The 【big red hair bow】, the 【black cat】 and the 【broom】 belong to Outfit 1 only: all three are clearly visible during Outfit 1 and none of them appears in Outfits 2, 3 or 4. Natural movement for a 【4-year-old girl】, realistic anatomy, believable fabric movement. Her clothing always stays modest and in place: every dress and skirt keeps its hem at her knees or longer the whole time and never flips or rides up above her knees. No extra props other than the 【broom】, the remote control and the 【staff】. After the first blade pass the 【black cat】 and the 【broom】 never reappear. No magic effects of any kind: no sparkles, snowflakes, ice, glowing light, smoke or particles. No text, captions, logos or watermark.
