Seedance 2.5 跑者浮板上平衡奔跑 运动动作提示词

Create a 15 second natural live action video in a 16:9 landscape frame, based on a real outdoor water obstacle challenge in a leafy public park. The scene takes place in daylight beside a shallow rectangular pond with slightly murky green water. A narrow path of connected brown wooden floating platforms stretches from the near bank to the far bank. The wet timber slats react physically to every footstep, dipping, rocking, flexing, and producing small realistic ripples and splashes. Mature trees surround the area. Alternating lime green and cream fabric shade panels soften the sunlight overhead. A small crowd of casually dressed spectators waits near the starting bank. Background signage remains distant and soft with no readable text. The main subject is a young adult wearing an olive green hooded jacket with the hood up, a loose white shirt extending below the jacket, black pants, and clean white athletic shoes. Keep the same face, body proportions, clothing, and footwear throughout. Movement must feel genuinely human. The subject begins slightly cautious, then speeds up as balance improves. Arms extend instinctively, shoulders counter rotate, knees bend naturally, feet land with believable weight, fabric shifts with motion, and shoes compress briefly against each wet board. For the first two seconds, show a wide establishing view. The floating walkway fills the lower foreground while spectators gather toward the left. The subject leaves the group and commits to the first platform. From two to five seconds, use a handheld camera at standing eye level as the subject accelerates toward the middle. Pan smoothly to the right with subtle operator imperfections, tiny framing corrections, mild vertical bounce, and realistic motion blur. Let the subject grow larger in frame as they pass closer to camera. One platform dips under a landing and releases a small splash beside the shoe. From five to eleven seconds, follow the subject running away from camera along the long floating path. Use the walkway as a strong leading line through the center. The camera keeps panning and reframing naturally rather than moving with perfect precision. Water responds continuously with overlapping ripples, reflected leaves, broken highlights, and gentle wake around the shifting platforms. Spectators become less prominent while trees, open pond water, support poles, and a small shaded pavilion near the far side become clearer. Leaves overhead move subtly in a light breeze. From eleven to fifteen seconds, the subject reaches the final unstable sections. Add one believable moment of imbalance where a board tilts, both arms swing wider, and the subject recovers without falling. They take two quick final steps, land safely on the far bank, and continue forward a few paces. Keep the ending observational rather th
