COMPOSITION: Shot type: wide Angle: slight high, from the rim two steps to the side of her, looking across and down into the sinkhole, horizon tilted a few degrees Placement: off-center, the woman large in the left third and close to the lens, cut at the shins by the bottom edge, the water, boat, manta rays and far channel filling the center and right Look-room: right Foreground: mild occlusion, a few blurred hanging leaves at the left edge Crop: handheld, slightly imperfect. CAMERA PACK: Body: iPhone 13 with a scratched case, rear main camera, held vertically at chest height in one hand Lens / zoom: 1x main lens, mild wide, the lens glass smeared with sunscreen and fingerprints Aperture or phone mode: a frame grabbed from a video recording, auto exposure set for the shaded water Focus: sharp on her face and her near shoulder with the black emblem tattoo, natural falloff behind, the boat and manta rays still readable Film or sensor: computational RAW, small-sensor phone texture, video compression LIGHT: Source: overhead midday tropical sun through the open top of the cenote Quality: hard sun, with soft green bounce from the water rising onto the lower walls Color temperature: neutral daylight with a turquoise cast in the shaded rock Shadows follow that source. PHOTOGRAPHIC CHARACTER: Visible skin microtexture, pores, faint uneven tone, slight facial asymmetry. Flyaway hairs. Fabric weave, seams, pills, dust, scuffs. Grain or sensor texture that matches the camera pack. Catchlights only from the stated light. Highlights a little hot, shadows a little closed. Candid stance, catalog-unaware. A light milky veiling haze and a soft streak of flare across the upper frame from the smeared lens, contrast a little flattened. Sky and sunlit rock clipped to plain white, her sunlit shoulder edge blown out, shaded rock blocked up and noisy. Motion blur on the waving hand, slight overall softness from the shaky grip, crunchy phone sharpening halos on the leaves, blocky compression in the water and the far crowd. Plain, slightly green-shifted color straight out of the phone, an ordinary snapshot by a friend. Once the first still is locked, use this Seedance 2.5 prompt and you're good to go! [STYLE + CAMERA + ATMOSPHERE] Real phone footage shot by a friend: one continuous 30-second handheld take, no cuts. Shaky grip, clumsy tilts and digital zoom, smeared lens, blown-out sky, hard midday sun in a Caribbean cenote. [IMAGE REFERENCES] <<<img1>>> is the first frame: the video starts exactly on it. Keep the woman, her clothes and arm tattoo, the rock, the wooden boat, the manta rays and the crowd as shown. <<<img2>>> provides the small man's face, build, velvet tailcoat and curled-toe shoes. He is one meter tall. Do not use the background from this image. [TIMELINE] 0-7s: [Wide, handheld] She finishes her wave, turns to face the drop and warms up: quick little hops, shaking out her arms. The whole cenote claps in rhythm and chants {Eh! Eh! Eh!}. The rays keep circling below. 7-11s: [Tilt down, shaky zoom] The camera drifts past her to the water. A grey shark fin slides out of the shadow at the foot of the far wall, under the hanging roots, and cuts across the surface. Language: American English. The man filming mutters {Fuck.} then shouts {No, no, no!}. Nobody else notices. 11-16s: [Whip up, follow the fall] She bends her knees and launches into a huge laid-out backflip with a full twist, the camera chasing her down. She knifes into the water dead center of the ring of manta rays; a tall white splash, the rays glide outward. The cenote erupts in applause. 16-22s: [Zoomed, unsteady] She surfaces laughing, one fist up. The fin turns and heads straight for her. Cheers flip into screams, people point. She looks back, sees it and swims hard for the wooden boat. 22-26s: [Zoomed on the boat] She grabs the side of the boat. The fin stops behind her and rises out of the water: a rubber fin strapped with belts to the back of the small man from <<<img2>>> , tailcoat soaked and dripping, smiling perfectly calm. Screams collapse into laughter. She laughs too, unharmed. 26-30s: [Closing action] He climbs onto the bow and breaks into a very fast, silly footwork dance, curled shoes slapping the wet wood, arms stiff at his sides, face serene. The boat rocks, the passengers film him with their phones, everyone laughs and claps. [AUDIO] Diegetic only: chanting, clapping, echo off the rock, the splash, screams, laughter, the cameraman's voice close to the mic. No background music. No subtitles. [STYLE & QUALITY BOOSTERS] Photoreal phone video, coherent water physics, real weight in the fall, stable faces and clothing, one woman and one small man throughout, natural motion blur, phone compression and noise. Enjoy it! 🤛

Eh! Eh!}。蝠鲼继续在下方盘旋。 7-11 秒：[下倾，抖动变焦] 镜头越过她移向水面。一片灰色的鲨鱼鳍从远壁脚下、悬挂树根下方的阴影中滑出，在水面划过。语言：美式英语。拍摄者低声说 {Fuck.}，然后大喊 {No, no, no!}。其他人没有注意到。 11-16 秒：[上摇，跟随下落] 她屈膝发力，跃起完成一个巨大的展体后空翻加完整转体，镜头追随她下落。她直插入蝠鲼包围圈正中央的水中，溅起高高的白色水花，蝠鲼向外滑开。天坑爆发出掌声。 16-22 秒：[变焦，不稳定] 她浮出水面大笑，一只拳头高举。鱼鳍转向径直朝她冲来。欢呼瞬间变成尖叫，人们指着水面。她回头看到后，奋力向木船游去。 22-26 秒：[变焦对准木船] 她抓住船舷。鱼鳍停在她身后，并从水中升起：那是一条橡胶鱼鳍，用带子绑在来自 <<<img2>>> 的小个子背上，燕尾服湿透滴水，神态平静微笑。尖叫声化作笑声。她也笑了，安然无恙。 26-30 秒：[收尾动作] 他爬上船头，展开极快速、滑稽的脚步舞蹈，翘头鞋拍打湿木，双臂僵直垂在身侧，表情恬静。船摇晃，乘客们用手机拍摄他，所有人都笑着鼓掌。 [音频] 仅现场音：呼喊、掌声、岩壁回响、落水声、尖叫、笑声、拍摄者贴近麦克风的声音。无背景音乐。无字幕。 [风格与质量增强] 照片级真实感的手机视频，一致的水物理，下落有真实重量，面部与服装保持稳定，全程一位女性和一位小个子，自然运动模糊，手机压缩与噪点。 玩得开心！🤛
