时长与镜头：结构是"痛点 2 秒 + 黑场 1 秒 + 产品 3 秒"。黑场是整条的灵魂：它把观众的注意力"重置"一下，产品镜头才显得干净。很多模型单条里不愿意给纯黑，最稳的做法是分两条生成（痛点段、产品段），剪辑时中间插 0.5–1 秒黑场，碰撞声后期加。

怎么填变量：[智能控温保温杯] 换成"[恒温电热水壶]""[便携暖手宝]"，痛点段跟着改：被烫到 → 等水烧开等到不耐烦 → 冻得搓手。冷暖对比（冷白灯 → 金色阳光）不要改，它是"问题 → 解决"的视觉信号。

常见失败与调整：

• 嘴唇特写变形：改成"手指碰到杯壁被烫得缩回"，不出现嘴。
• 产品段的杯子和上传图不一样：把产品段单独做图生视频，首帧直接用产品图。

Vertical product ad with a hard pattern-interrupt. SUBJECT: a coffee vessel — first a scalding office mug, then [brand] temperature-smart tumbler. 0–2s (handheld micro-shake, cold fluorescent flicker): a plain mug on a gray desk erupts with violent steam, lips graze the rim and recoil, a sharp inhaled hiss. 2–3s (hard cut to pure black): one clean ceramic clink, silence. 3–6s (slow 30mm push-in, shallow depth, warm window bokeh): the [brand] tumbler lands in golden afternoon light, the lid twisting open to reveal a calm matte-still coffee surface at drinkable temperature, only a gentle thread of vapor rising. FIDELITY: the tumbler keeps one consistent silhouette, logo placement, and brushed-metal finish across the cut — no deformation, label drift, doubling, or texture flicker. SOUND: flinch breath, the black-frame clink, then a soft pour and a satisfied exhale.
