veo 3 JSON 提示词：驾驶第一视角撞上西瓜堆（挡风玻璃果汁爆溅慢动作 · 禁止项写法）

时长与镜头：8 秒一个车内固定 POV：平稳行驶 → 冲近 → 撞击慢动作 → 果汁滑落。整条视频都"只透过挡风玻璃"，这个限制让画面非常集中，撞击的冲击力也更强。

visual_rules 写法值得学：prohibited_elements 列出"司机的脸、车外视角、后视镜画面、字幕"等不允许出现的东西，相当于 JSON 里的负面提示。Veo 官方建议负面提示写成"名词"而不是"不要 xxx"，这里正好是名词列表。你写其他 POV 视频时也可以加这一段，防止模型擅自切到第三人称。

怎么填变量：[西瓜] 换成"一堵纸箱墙""一大堆彩色气球""一片泡沫雪堆"；[乡间公路] 换成"沙漠公路""废弃停车场"。爽感视频的关键是"撞上的东西要无害且飞溅效果好"。

常见失败与调整：

• 撞击后切到了车外：保留 prohibited_elements，并在 shot 里重复"全程车内视角"。
• 果汁效果像贴图：写"果肉有厚度，顺着玻璃缓慢往下滑，留下红色痕迹"。
• 晃得太厉害看不清：写"撞击晃动只持续半秒"。
