时长与镜头：分开（2 秒）→ 环绕展示（2 秒）→ 合体（2 秒），在可灵选 5 秒时每段约 1.7 秒，选 10 秒时可把环绕段放慢。想做成循环视频，在结尾加"最后一帧与第一帧相同"。

怎么用首尾帧：可灵支持首尾帧时，效果最稳的做法是——首帧放"产品完整合体"的图，尾帧放"零件分开悬浮"的图（可以用图像模型先做一张爆炸图），提示词只写中间的运动过程。

怎么填变量：零件写 3–5 个就够，太多会数不清；换成充电宝就写"[外壳、电芯、电路板、按键]"。

常见失败与调整：

• 零件越分越多：在零件清单后面写明"一共 4 个零件"。
• 合体时零件穿插：把合体速度写慢，"缓缓聚拢、依次归位"。
• 品牌名乱码：删掉品牌名一句，后期加 Logo。

Wireless earbuds and their charging case float in exploded-view layout against a deep-navy gradient void, lit by one soft overhead box. 0-2s: components drift apart in zero gravity — lid, both buds, and silicone tips suspended and slowly rotating, brushed-metal and matte-plastic surfaces catching crisp specular highlights. 2-4s: a parallax orbit left as a cyan accent edge-light traces every seam, micro-reflections rolling along the glossy stems. 4-6s: the parts magnetically draw back together and seat with a clean close, [brand] etched on the hinge. Each part holds constant geometry, scale, and finish — no jitter, duplication, intersection clipping, or warping. Sound: weightless hum, a magnetic click, soft confirmation chime.
