veo 3 JSON 提示詞：駕駛第一視角撞上西瓜堆（擋風玻璃果汁爆濺慢動作 · 禁止項寫法）

時長與鏡頭：8 秒一個車內固定 POV：平穩行駛 → 衝近 → 撞擊慢動作 → 果汁滑落。整條影片都"只透過擋風玻璃"，這個限制讓畫面非常集中，撞擊的衝擊力也更強。

visual_rules 寫法值得學：prohibited_elements 列出"司機的臉、車外視角、後視鏡畫面、字幕"等不允許出現的東西，相當於 JSON 裏的負面提示。Veo 官方建議負面提示寫成"名詞"而不是"不要 xxx"，這裏正好是名詞列表。你寫其他 POV 影片時也可以加這一段，防止模型擅自切到第三人稱。

怎麼填變量：[西瓜] 換成"一堵紙箱牆""一大堆彩色氣球""一片泡沫雪堆"；[鄉間公路] 換成"沙漠公路""廢棄停車場"。爽感影片的關鍵是"撞上的東西要無害且飛濺效果好"。

常見失敗與調整：

• 撞擊後切到了車外：保留 prohibited_elements，並在 shot 裏重複"全程車內視角"。
• 果汁效果像貼圖：寫"果肉有厚度，順着玻璃緩慢往下滑，留下紅色痕跡"。
• 晃得太厲害看不清：寫"撞擊晃動只持續半秒"。
