Seedance 2.0 Volcano Soap Bubble Video

【Basic Settings】
15 seconds, 9:16 vertical screen, one continuous shot, realistic documentary photography style. Records the complete process of a man dropping a giant soap from a helicopter into a volcanic crater, followed by large amounts of soap bubbles rising from the volcano and flooding into the cabin.

Present the surreal event through on-site observation, with natural and restrained imagery and realistic character reactions. No comedy performances, funny actions, or deliberately designed gags. One continuous shot throughout, no cuts, transitions, hidden edits, slow motion, or time jumps.

【Characters and Props】
An adult male wearing a dark outdoor jacket, long pants, and boots, with a waist safety belt connected to the cabin anchor point, located inside the open side door of the helicopter.

The man holds a giant pink soap approximately 80cm long, 45cm wide, and 25cm thick with both arms. Rounded rectangular prism, smooth surface with slight wet reflections, clear thickness and weight. No packaging, no text.

Real seats, fixed handles, metal door frames, and floor visible inside the helicopter. The pilot remains in the front cockpit. Character, cabin, and prop appearances remain consistent throughout.

【Environment and Photography】
Daytime, natural light. Dark rough rock walls surround a wide volcanic crater, with slowly rolling orange-red magma at the bottom, and slight thermal disturbance in the air.

The helicopter hovers above the edge of the crater, with the side door facing the interior of the volcano. The composition clearly shows the positions of the man, the door, and the drop point below, maintaining consistency between drop height and actual fall time.

The camera is always held by the shooter inside the cabin, completing forward tilts, upward movements, and rotations near the side door. Wide-angle documentary composition, with small vibrations caused by rotors and natural handheld adjustments, actions clearly discernible. Natural exposure and color, retaining real textures of skin, clothing, rock walls, and metal.

【Continuous Time Sequence | 0:00–0:04 | Dropping the Giant Soap】
Shot from inside the cabin towards the side door. The man and the giant soap occupy the foreground, with the volcanic crater clearly visible through the door below.

The man presses the bottom edge of the soap against the threshold, steadies it with both hands, bends his knees to shift his center of gravity forward, and pushes the soap outward. His arms straighten as he pushes; once the soap's center of gravity crosses the threshold, his hands clearly release.

The soap leaves the cabin, accelerating downward with a slight rotation. The man withdraws his hands, steadies himself on the cabin handle, and stays in place to observe.

The camera naturally tilts forward, continuously panning down along the soap's trajectory, keeping a small section of the door frame at the edge of the frame. The soap gradually shrinks in depth, contacts the magma below, causing local churning. Present the entire falling process completely, without skipping distance or suddenly cutting to a close-up of the landing point.

【Continuous Time Sequence | 0:04–0:09 | Foam Generation, Large Amounts of Bubbles Rising】
The camera maintains the downward tilt. Fine white bubbles appear where the soap contacts the magma, then the foam continues to expand, gradually covering the surrounding magma.

Transparent soap bubbles continuously bulge out and detach from the churning white foam, drifting towards the helicopter with the rising airflow. Initially only a few scattered ones, then the number increases rapidly, forming a dense bubble group with front-to-back depth.

Bubbles range in size from grapes to basketballs, with thin-film reflections and faint iridescence on the surface, allowing visibility of the volcano and rock walls through the bubble membrane. Rising speeds vary slightly, colliding and deforming with each other, some popping naturally, while more continue to form behind.

The camera continuously observes the approach of the bubbles. The distant volcano is still visible through gaps, while nearby bubbles gradually occupy more of the frame. The white foam on the magma and the transparent bubbles rising into the air are clearly distinguished.

【Continuous Time Sequence | 0:09–0:13.5 | Bubbles Arrive, Flooding into Cabin】
Bubbles rise to the height of the cabin door, swept up by the rotors and airflow around the fuselage. Some pop or deviate, while more continuously flood in from outside the side door.

The camera follows the bubbles continuously lifting, smoothly turning back into the cabin, refocusing on the man. Shooting position and door frame direction remain consistently aligned, cannot suddenly change to an external view.

The man holds a fixed handle with one hand, leans slightly inward, and naturally raises his other hand to shield his eyes from bubbles approaching too closely. He mainly observes the changes before him, not looking at the lens, not performing exaggeratedly, and not speaking.

Bubbles constantly diffuse from the door into the cabin interior, squeezing between seats, the man's shoulders, and the camera. Nearby bubble membranes gently deform and slide, leaving wet white foam on hair, sleeves, and seats after popping. More bubbles immediately fill in, gradually obscuring cabin structures and character outlines.

【Continuous Time Sequence | 0:13.5–0:15 | Cabin Filled with Bubbles, Direct End】
The camera maintains the current cabin perspective, only retreating slightly with the shooter's body.

Large amounts of bubbles have already crowded the door and surroundings of the person, with the man's upper body almost obscured. Bubbles continue to naturally crowd, drift, and pop; through local gaps, dark sleeves and the hand holding the handle can be seen.

End directly here, do not add actions like parting bubbles to reveal face, looking at the lens, or being covered again; no freeze frame, no pull back.

【Sound】
Real rotor sounds and wind noise from the door persist throughout, accompanied by the sound of soap rubbing against the threshold, low rumbling of distant volcanic churning, and subtle dense popping sounds after bubbles enter the cabin. Sound distance changes naturally with camera orientation. No background music, narration, dialogue, or comedy sound effects.

【Key Constraints】
9:16 vertical screen, 15 seconds, one continuous shot throughout, realistic documentary photography texture. Camera always located near the side door inside the same helicopter.

Only one giant pink soap, which does not reappear in the man's hands after being thrown. Bubbles first generate from the volcano, then continuously rise to the door and flood into the cabin, cannot appear out of nowhere. No single giant bubble wrapping the helicopter.

Transparent bubbles have clear thin-film structures, white foam consists of fine bubbles, avoid depicting as smoke, cotton, or snow. Only use the last 1.5 seconds to show the state where the man's upper body is almost obscured by bubbles, then end immediately. No subtitles, logos, or watermarks.

【基础设定】
15秒，9:16竖屏，一镜到底，真人纪录片摄影风格。记录一名男子从直升机向火山口投下巨型肥皂，随后大量肥皂泡从火山升起，涌入机舱的完整过程。

以现场观察的方式呈现超现实事件，画面自然、克制，人物反应真实。没有喜剧表演、搞笑动作或刻意设计的包袱。全程同一个连续镜头，无切镜、转场、隐藏剪辑、慢动作或时间跳跃。

【人物与道具】
一名成年男子，穿深色户外夹克、长裤和靴子，腰部安全带连接机舱固定点，位于打开的直升机侧舱门内。

男子双臂抱着一块约80厘米长、45厘米宽、25厘米厚的巨型粉色肥皂。圆角长方体，表面光滑，带少量湿润反光，具有明确厚度与重量。无包装、无文字。

直升机内部可见真实座椅、固定把手、金属门框和地板。驾驶员留在前方驾驶舱。人物、机舱与道具外观全程保持一致。

【环境与摄影】
白天，自然光。深色粗糙岩壁围绕宽阔火山口，底部是缓慢翻滚的橙红色岩浆，空气中存在轻微热扰动。

直升机悬停在火山口边缘上方，侧舱门朝向火山内部。构图清楚交代男子、舱门与下方落点的位置，投掷高度与实际下落时间保持一致。

摄影机始终由机舱内的拍摄者持握，在侧舱门附近完成前倾俯拍、抬镜和回转。广角纪实构图，带有旋翼引起的细小振动与自然手持调整，动作清楚可辨。自然曝光与色彩，保留皮肤、衣料、岩壁和金属的真实纹理。

【连续时间序列｜0:00—0:04｜投下巨型肥皂】
从机舱内部朝侧舱门拍摄。男子和巨型肥皂占据近景，下方火山口透过舱门清楚可见。

男子把肥皂下缘抵在门槛，双手扶稳两侧，屈膝前移重心，将肥皂向外推出。双臂随推送伸直，肥皂重心越过门槛后，双手明确松开。

肥皂脱离机舱，带着轻微翻转向下加速坠落。男子收回双手，扶稳机舱把手，留在原位观察。

摄影机自然前倾，沿肥皂轨迹连续向下俯拍，画面边缘保留一小段门框。肥皂在纵深中逐渐变小，接触下方岩浆，激起局部翻动。完整呈现下落过程，不跳过距离，不突然切成落点特写。

【连续时间序列｜0:04—0:09｜泡沫生成，大量泡泡升起】
摄影机保持俯拍。肥皂接触岩浆的位置出现细密白色气泡，随后泡沫持续膨胀，逐渐覆盖周围岩浆。

透明肥皂泡从翻涌的白色泡沫中连续鼓起、脱离，随上升气流向直升机方向飘来。最初只有零星几颗，随后数量迅速增加，形成具有前后纵深的密集泡泡群。

泡泡大小从葡萄到篮球不等，表面具有薄膜反光和微弱虹彩，可以透过泡膜看见火山与岩壁。上升速度略有差别，彼此碰撞、变形，部分自然破裂，后方继续生成。

摄影机持续观察泡泡接近的过程。远处火山仍能从间隙中看见，近处泡泡逐渐占据更多画面。岩浆上的白色泡沫与升空的透明泡泡具有明确区别。

【连续时间序列｜0:09—0:13.5｜泡泡抵达，涌入机舱】
泡泡升至舱门高度，被旋翼与机身周围的气流卷动。一部分破裂或偏离，更多从侧舱门外持续涌入。

摄影机跟随泡泡连续抬起，平滑转回机舱，重新拍到男子。拍摄位置和门框方向连续一致，不能突然变成机外视角。

男子一只手握住固定把手，身体略微向舱内退让，另一只手自然抬到面前挡开贴近眼睛的泡泡。他主要观察眼前变化，不看镜头、不夸张表演、不说话。

泡泡从舱门向机舱内部不断扩散，挤在座椅、男子肩膀和摄影机之间。近处泡膜轻轻变形、滑动，破裂后在头发、衣袖和座椅上留下湿润白沫。更多泡泡紧接着填入，机舱结构和人物轮廓逐渐被遮挡。

【连续时间序列｜0:13.5—0:15｜机舱被泡泡填满，直接结束】
摄影机保持当前机舱视角，仅随拍摄者身体轻微后退。

大量泡泡已经挤满舱门和人物周围，男子上半身几乎被遮住。泡泡仍在自然拥挤、漂动和破裂，透过局部间隙能看见深色衣袖与握住把手的手。

到此直接结束，不再增加拨开泡泡露脸、看向镜头或再次被覆盖的动作，不定格、不拉远。

【声音】
真实旋翼声与舱门风声贯穿全程，配合肥皂摩擦门槛的声音、远处低沉的火山翻动声，以及泡泡进入机舱后细微密集的破裂声。声音距离随摄影机朝向自然变化。无背景音乐、旁白、台词或喜剧音效。

【关键约束】
9:16竖屏，15秒，全程一镜到底，真人纪录片摄影质感。摄影机始终位于同一架直升机内部的侧舱门附近。

只有一块巨型粉色肥皂，投出后不再出现在男子手中。泡泡先从火山生成，再连续升至舱门并涌入机舱，不能凭空出现。没有单个包裹直升机的巨型泡泡。

透明泡泡具有清楚的薄膜结构，白色泡沫由细密气泡组成，避免表现成烟雾、棉花或雪。末尾仅用1.5秒呈现男子上半身几乎被泡泡遮住的状态，随即结束。无字幕、标志和水印。
