  "description": "给一张商品图和几条卖点,写一条分拍的口播脚本(第一拍是钩子、最后一拍是行动号召,最多 12 拍),每一拍出一张带商品的竖幅画面、按这一拍的时长铺上时间线,念这一拍的画外音、对齐这一拍的开头(有克隆音色优先用,没有就用免费的 Edge 音色),再铺上屏幕短句,导出竖屏成片。没有人出镜。卖点只用你给的那几条,不编功效和数据。视频模型可用时每一拍动起来:这一拍的画面当首帧出一段视频,铺上时间线的是视频,每拍一样长(开始节点的 beat_seconds,建图时取这个模型出得了的那一档)。花费量级:每一拍一次付费出图,动起来时每一拍再加一次付费视频生成 —— 拍数约为目标时长 ÷ beat_seconds,默认 30 秒、每拍 5 秒约 6 拍,就是 6 张图加 6 段视频。这一份带着「把这一拍动起来」:开始节点的 beat_seconds 是每一拍几秒,挑的视频模型要出得了这个时长。没有视频模型的话,导入后在画布上打开逐拍的那个循环,删掉「把这一拍动起来」「归档这一拍的视频」「这一拍的视频不出声」三个节点,再把「出这一拍的画面」的结果连到「按这一拍的时长铺上去」的素材那一格 —— 每一拍就按 beat_seconds 铺一张静图。也可以在应用的模板库里直接添加:没有视频模型时建出来的就是静图版。",
