Seedance 2.5 女子推木船下水 电影写实提示词

Create an ultra-realistic cinematic 15-second vertical 9:16 video demonstrating real-world physics through one continuous, believable sequence. Scene: a young woman walks along a riverside carrying a small ball and approaches a wooden boat floating near the shore during golden hour. From 0–3 seconds, she walks naturally toward the boat; her footsteps demonstrate gravity, weight, friction, balance, inertia, and realistic acceleration and deceleration. Loose hair and clothing react naturally to wind and air resistance. From 3–6 seconds, she gently pushes the boat into the water and steps inside. The boat moves backward as a realistic reaction to her push, demonstrating Newton’s third law and conservation of momentum. Her body shifts slightly because of inertia as the boat accelerates, while friction and water drag gradually reduce the boat’s motion. From 6–9 seconds, she drops the ball inside the boat; gravity causes it to fall with realistic acceleration, bounce once according to its elasticity and collision physics, and settle because of friction. From 9–12 seconds, she throws the ball forward; the ball follows a realistic curved trajectory under gravity and air resistance while the moving boat continues forward because of momentum. The ball lands on the water, creating a realistic splash, ripples, displacement, surface tension, buoyancy, and fluid-dynamic interaction. From 12–15 seconds, the boat continues gliding naturally, creating a realistic wake behind it as water resistance and drag gradually reduce its speed. Throughout the entire video, accurately simulate Newton’s three laws, gravity, inertia, momentum, conservation of momentum, conservation of energy, friction, acceleration, deceleration, collision forces, elasticity, mass, weight, air resistance, drag, buoyancy, pressure, surface tension, fluid dynamics, displacement, and realistic cause-and-effect interactions. Every movement must have believable physical consequences and correct timing. Objects must maintain consistent mass, scale, position, texture, and physical properties from frame to frame. Use realistic water reflections, shadows, wind movement, natural motion blur, physically accurate lighting, photorealistic materials, cinematic depth of field, smooth camera movement, and professional film quality. No impossible movement, no floating objects, no teleportation, no sudden unexplained acceleration, no object clipping, no distorted anatomy, no duplicated objects, and no violation of realistic physics. Total duration exactly 15 seconds.
