火山坡骑行动作序列

超写实电影级 15 秒动作序列。一名骑手从陡峭的火山坡上疾驰而下，身后熔岩不断推进。画面包含热浪扭曲和发光的岩石。运动轨迹为重力驱动的下坡，全程无转向。采用连续无缝的运镜，与坡度方向保持一致。起始镜头位于后上方，与下坡速度同步。随后平滑过渡到侧面角度，进行平行追踪。镜头压低贴近地面，以强调速度感。接着升起至更宽的后方跟拍视角，展现身后的熔岩。序列中段，地面出现陡降。镜头保持对齐，跟随下坡弧线运动。在下落过程中略微转向前方，落地后回到后方追踪视角。结尾以更宽的俯拍视角持续下坡。

Hyper-realistic cinematic 15s action sequence. A rider descends a steep volcanic slope as lava advances behind. Heat distortion, glowing rock. Motion is gravity-driven downhill. No turning. Continuous seamless camera, aligned with slope direction. Start behind and slightly above, matching descent. Slide outward to a side angle, tracking parallel. Dip low near the ground, emphasizing speed. Rise again into a wider trailing angle showing lava behind. Mid-sequence, the ground drops sharply. Camera stays aligned, following the descent arc. Shift slightly forward-facing during the drop, then return to rear tracking on landing. End continuing downhill with a wider elevated angle.
