机械花绽放

生成一段20秒、16:9宽屏的电影感视频。主题为“机械花绽放”。整体呈现具有强烈视觉冲击力的高端科技广告风格，采用照片级真实材质、精确灯光和细腻的电影级调色。使用一个连续的微距推进镜头并保持构图稳定：0至5秒，一枚金属花苞置于近乎黑暗的环境中，细微高光逐渐显现拉丝金属与透明玻璃花瓣；5至13秒，镜头逐步进入花瓣之间的精密机械结构，展示微型齿轮、活塞、环形组件和活动关节，以细腻且符合物理规律的方式运动；13至20秒，镜头随着机械花完全展开而移出结构，受控的明亮光波向四周黑暗空间扩散，形成高潮式最终画面。强调真实的物理光照、精细的金属与玻璃表面、细腻反射、同步而轻柔的机械运动、空间纵深、尺度感和高级商业电影摄影。不要人物、标志、品牌元素、字幕、可读文字、水印、音频或剪辑切换。

【English Prompt】
Generate a 20-second cinematic video in 16:9 widescreen. Theme: “Mechanical Flower Bloom.” Create a high-end technology advertisement with strong visual impact, photorealistic materials, precise lighting, and refined cinematic color grading. Use one continuous macro camera push-in with stable composition: 0–5 seconds, a metallic flower bud rests in near darkness, with subtle highlights revealing brushed metal and transparent glass petals; 5–13 seconds, the camera gradually enters the precision mechanical structure between the petals, revealing miniature gears, pistons, rings, and articulated joints moving delicately and physically plausibly; 13–20 seconds, the camera emerges as the mechanical flower opens completely, sending a controlled wave of luminous light outward into the surrounding darkness for a climactic final frame. Emphasize realistic physical illumination, detailed metal and glass surfaces, fine reflections, delicate synchronized motion, depth, scale, and premium commercial cinematography. No people, no logos, no brand references, no captions, no readable text, no watermark, no audio, and no cuts.
