时长与镜头：4 个镜头约 12 秒。平台只能选 5 秒或 10 秒时，删掉镜头三；想要更稳，可以把镜头一、镜头四各自单独生成，再在剪辑软件里拼接。

怎么填变量：[金色机械表] 写清材质和颜色，如"银色钢壳蓝盘手表"；[制表工坊] 可换成"珠宝工作室""皮具工坊"，整条提示词就能改做首饰、皮包的工艺广告。有实物照片时，上传为参考图并加一句"手表外观以参考图为准"。

常见失败与调整：

• 手和镊子穿模：把镜头二改成"零件被缓缓放进机芯，只露出镊子尖"，减少手指出镜。
• 表盘刻度、指针数量混乱：写明"三根指针、12 个刻度"，或者最后几秒用真实产品照片替换。
• 冒出假 Logo 或乱码文字：保留最后一句"不要文字和 Logo"，品牌标识后期叠加。
