veo 3 JSON 提示词：外星青蛙带你参观飞船（角色口播 + 道具变出披萨 · 搞笑短视频）

时长与镜头：8 秒内三句台词 + 一个道具特效：介绍机器 → 变出披萨 → 对镜头总结。台词是 Veo 3 系列的强项，但每句要短（中文 10–15 字以内），三句已经是 8 秒的上限，再多就会说不完被截断。

action_sequence 的写法值得学：把镜头、台词、动作、结果按顺序放进一个数组，每一项是一个"节拍"。这比把所有内容写成一段话更容易控制"先说什么、再做什么"。做产品拟人化讲解时，把青蛙换成你的品牌吉祥物，机器换成你的产品，三句台词就是三个卖点。

怎么填变量：[黏糊糊永动料理机] 和三句台词都可以换。角色换成"一只机器人管家""一只会说话的盆栽"，环境换成"厨房""实验室"。

常见失败与调整：

• 台词说不完：删到两句，或每句砍到 8 个字左右。
• 自动配了背景音乐：保留 negative_prompt 里的"背景音乐"。
• 披萨出现得太突然或没出现：result 里写"橙色黏液旋转、慢慢凝固成一块披萨"。
