电影海报是最小的预告片——一张图要在四分之一秒内说清类型、情绪和赌注。AI 最常忘的三件事:1 个强主体(不是一群人)、真正有层次的氛围(不是平涂)、刻意留出的标题字位。下面这 12 条 Prompt 把这三点同时锁住,出图直接可用,不只是”插画”。同题材的封面构图语言可参考 书籍封面 Prompt。

12. 同片 4 个版本扫一遍
generate 4 poster variants for the same film "{logline}". Keep subject identical. Vary: (a) palette (warm vs cool), (b) crop (wide vs tight), (c) light direction (front vs back), (d) negative-space placement (top vs bottom). All vertical 2:3, all with reserved title band, no rendered text.
怎么继续打磨
出图之前先决定标题位置——顶部、底部、还是左边竖排——然后在 Prompt 里明确”该区域留白给字”。不要让模型生成片名文字,AI 渲染的字在海报上永远是坏的,回到 Figma / PS 用真字体压上去就好。每个 Prompt 都建议带 “no rendered text” 收尾。
容易踩的坑
- 没给字留位,画面填满,最后字浮在画上
- 主体被细节淹没,眼睛找不到落点
- 让模型生成片名文字——AI 海报字永远是坏的
- 氛围太通用,没确定调色(teal-orange、单色、金色)
- 长宽比混乱,电影院海报应固定竖版 2:3
