H3「水线穿越」浴缸写真 MV：半水下镜头 + 泡沫前景的一镜到底玩法

 

这是一个比较适合 MiniMax H3 的浴缸写真 MV 拍摄方案。

它不采用传统的正面、侧面、俯拍反复切镜，而是把**“水面”本身作为整支 MV 的镜头语言**：摄影机始终保持一半在水面上、一半在水面下，从浴缸前端穿过大片虚化泡沫，逐渐靠近人物，最后以水面仰角停在人像附近。

这种设计尤其适合有限分辨率的视频生成：泡沫、水面和浴室背景承担大量虚化区域，把更多视觉细节留给人物的脸、头发和主体轮廓。

使用方式

准备两张参考图：

• Picture 1：人物脸部参考用于锁定人物身份。 重点保持脸型、五官、发型、年龄感和辨识度。
• Picture 2：人物四视图用于确定人物完整外观、服装、比例以及不同角度下的一致性。 不要在提示词中重新设计服装，让 Picture 2 决定。
• 文字 Prompt 只负责：浴室环境 水面和泡沫 摄影风格 镜头运动 人物动作 光线 声音

核心拍摄逻辑

整段视频尽量保持一镜到底：

浴缸前端 → 泡沫山前景 → 穿过泡沫 → 人物逐渐出现 → 靠近人物 → 回眸 → 水线保持 50/50 → 最后形成轻微仰拍人像

关键不是让镜头去“寻找身体”，而是让：

水面 + 泡沫 + 浅景深 + 人脸

构成整个 MV 的视觉主体。

summary:
[reference generation + keyframe completion] The target video is a continuous single-shot lifestyle MV filmed from inside the bathtub using a distinctive split-level waterline camera technique. The camera remains approximately half above the water and half below the water throughout the entire shot.

The waterline remains visible across the frame as a natural horizontal visual division. Large clusters of soft white bath foam occupy the foreground and partially obscure the lower composition. The camera slowly travels forward through the foam, gradually revealing the person.

<Picture 1> locks the person's facial identity. <Picture 2> determines the person's complete visible appearance, clothing, outfit state, proportions, and consistency from different viewpoints.

The person's outfit remains unchanged throughout the entire video.

The visual language is natural smartphone lifestyle photography combined with an unusual waterline perspective: warm creamy-white tones, low saturation, soft bathroom lighting, thin steam, gentle diffusion, subtle bloom, low contrast, realistic skin texture, and shallow depth of field.

detailed_description:
The target video is one continuous uninterrupted shot with no cuts.

The defining visual technique is a split-level waterline camera. The camera lens remains approximately half above the water surface and half below the water surface throughout the entire shot. The waterline stays visible and naturally divides the upper and lower portions of the image.

The camera is physically inside the bathtub and extremely close to the water surface. The underwater portion of the lens captures soft water movement, foam fragments, bubbles, and subtle underwater distortion. The above-water portion captures the person's face and the softly illuminated bathroom.

Large naturally formed clusters of white bath foam occupy the foreground. The foam behaves like a soft irregular foreground mountain range. The camera slowly travels through gaps between the foam clusters rather than jumping above them.

The foam remains between the camera and the lower portion of the person, creating a natural visual barrier. The composition remains focused on the person's face, eyes, wet hair, shoulders, and upper-body silhouette. The framing does not isolate or emphasize intimate areas.

[Shot 1]
At the beginning of the video, the camera is positioned very close to the front portion of the bathtub, with approximately half of the lens above the waterline and half below it.

The foreground is dominated by large soft clusters of white bath foam. The foam is extremely close to the lens and therefore heavily defocused, producing a dreamy foreground texture.

Only fragments of the bathroom and warm ceiling light are visible above the waterline.

The camera begins a slow forward Tracking Shot with very small amplitude.

It moves through the foam continuously and smoothly. Individual bubbles pass close to the lens while the waterline remains stable across the frame.

The person is initially partially hidden behind the foam.

As the camera advances, the foam gradually opens into a natural visual gap.

The person's upper body begins to emerge from behind the foam. The face remains the main point of focus.

Wet hair rests naturally around the face and shoulders.

The person looks slightly away from the camera at first.

The above-water half of the image remains warm, creamy, and softly illuminated. The underwater half contains subtle blue-white water distortion and drifting bubbles while remaining visually consistent with the warm overall palette.

The camera continues its uninterrupted forward movement.

The person's face becomes increasingly prominent while the foam remains blurred in the immediate foreground.

The person slowly turns the head toward the camera.

The eyes eventually meet the lens.

The camera makes a very subtle upward pitch while maintaining the approximately 50/50 waterline split.

The movement should feel like a real physical camera moving through bathtub water rather than a digital camera effect.

The camera travels farther forward through another cluster of foam.

The foam briefly crosses the foreground and partially obscures the lower composition before drifting aside.

The person remains relaxed and stationary, allowing the camera movement to create the visual progression.

The person gently raises one hand and adjusts a small section of wet hair beside the face.

The hand then returns naturally.

The camera remains at water level.

No transition to a conventional dry camera angle occurs.

As the camera reaches the person's closer position, the perspective becomes a subtle low-angle waterline portrait.

Approximately half of the frame continues to exist above the water surface and half below it.

The waterline remains visible.

The person's face, eyes, wet hair, and expression are sharply resolved.

The foam remains a soft foreground layer between the camera and the lower composition.

The camera continues its slow forward movement toward the person's position while maintaining the split-level composition.

Near the end of the shot, the camera reaches approximately the person's waist-level position while still maintaining the same half-above-water, half-below-water configuration.

The camera angle becomes slightly upward-facing from the waterline.

The person looks down toward the camera and then gently raises the eyes to meet the lens.

The foreground remains dominated by soft white foam, which naturally blocks the lower portion of the composition.

The camera does not dive underwater and does not rise completely above the water.

The 50/50 waterline relationship remains visually recognizable until the final frame.

The camera settles into a very subtle low-angle waterline portrait.

The person's face occupies the dominant upper portion of the frame.

Warm bathroom light creates gentle highlights in the wet hair and eyes.

Soft steam drifts through the background.

The underwater half contains delicate ripples and tiny bubbles.

The foreground foam remains softly blurred.

The person maintains a relaxed natural expression and gives a very subtle smile.

The camera stops moving without pulling away.

The final frame remains a distinctive split-level waterline composition, with approximately half the lens above the water and half below it.

No camera cut occurs at any point.

The person's identity remains consistent with <Picture 1>, while the complete visible appearance and outfit remain consistent with <Picture 2>.

overall_soundscape:
Soft bathtub water movement surrounds the camera throughout the shot. Small bubbles rise near the lens, foam shifts gently against the water surface, and subtle ripples accompany the camera's forward movement. Quiet bathroom room tone, faint ventilation, soft breathing, and occasional water droplets remain natural and understated.

non_diegetic_music:
A minimalist atmospheric MV score at a slow tempo. Sparse warm electric piano, soft underwater-like synth textures, gentle low-frequency pulses, and very subtle percussion create a continuous flowing rhythm. No vocals. The music gradually becomes slightly fuller as the camera emerges through the foam and reaches the final waterline portrait, then settles into a soft sustained ending.
