倾倒镜头能不能用，全看液体的”重量感”对不对：威士忌要落成厚重的琥珀色丝带，啤酒泡沫要开花再落下、收成一圈干净的奶油头，意式浓缩要看见 crema 的旋纹。下面这 10 个模板把粘稠度、冰块互动、玻璃挂雾和单灯硬光全部写死，模型基本没空间瞎发挥。所有片段控制在 5 到 8 秒——倾倒这种液体物理过了这个时长就开始崩。
一个好视频 Prompt 通常包含什么
每条 Prompt 都要凑齐这 5 层：
- 镜头焦段：100mm 微距、50mm 定焦、35mm anamorphic；越近越适合倾倒特写
- 灯位：单侧硬光、单顶暖光、或从液体背后打透光让颜色发亮
- 机位运动：锁定三脚架、慢推、或 90 度内的慢弧；不要徒手晃
- 色调：威士忌啤酒走暖琥珀，红酒深红，抹茶冷绿，牛奶纯白
- 主体克制：一只杯、一种液体、一个动作；中途换手或换装饰几乎必崩
时长：5 到 8 秒。倾倒动作本身要占整个片段中段的 60% 左右。

- 液体跑成 CG 糖浆：把 “thick”、“viscous” 删掉；直接说出酒名（amber whisky / golden lager），让模型靠参照锚定
- 冰块互相穿模或融在一起：要一两块清冰，不要一杯碎冰；碎冰每帧都在变
- 泡沫一直往上长溢出杯口：写一句 “foam settling into a clean half-inch head”，让泡沫有个明确收尾
- 双手倒酒：一只手、一只杯、一个动作；两只手几乎一定会在中途换指
- 时长超过 8 秒：液体物理会漂，液柱扭曲、杯型变形、颜色还会换
下一步怎么改得更好
- 每条倾倒 Prompt 都配一束单一硬光并写明方向；柔和均匀光会把液体打平，广告需要的高光反而不见了
- 玻璃挂雾是”冷感”的关键，写 “condensation already on the glass” 让冷凝在镜头开始时就已存在，避免模型动画式生成
- 背光透光镜（模板 6、9）写 “back light glowing through the liquid”，颜色才会从酒体透出来，而不是反射在杯子表面
- 冰块数量要锁死：“one large clear ice cube” 或 “three clear ice cubes” 都比写 “ice” 稳得多
- 不要奢望一条 15 秒长片，剪 3 到 4 个 6 秒短片更稳；广告本来就要互剪，从一开始就按互剪节奏生成
常见问答 (FAQ)
Q: 为什么液体经常跑成糖浆质感？
A: 两个原因。要么是 “thick”、“viscous” 触发了凝胶感，要么是没有给模型一个具体液体作参照。换成 “smooth heavy ribbon stream”，并把酒名直接写出来。
Q: 怎么让啤酒泡沫只到杯口、不一直溢出来？
A: 在 Prompt 里给泡沫一个明确边界，例如 “foam settling into a clean half-inch head” 或 “foam crown rising in slow bloom and settling”。不给边界的话模型会一直加。
Q: 哪个模型对倾倒镜头最稳？
A: Veo 3 的液体物理最稳，特别是液体加泡沫这种混合状态。Sora 在静态特写和冰块上靠谱。Kling 在茶汤、抹茶上没问题，但啤酒泡沫偏弱。
Q: 怎么让玻璃杯本身不变形？
A: 控时长 5 到 8 秒、用锁定三脚架或小角度慢弧、不要同时再叠一个 360 度旋转。
Q: 能不能生成一条 15 秒的长倾倒？
A: 现阶段几乎一定崩。生成两条 6 到 7 秒，再交叉淡化拼接。一条长片要么液柱扭曲，要么颜色中途变。
