OriginalShow the original description

生成视频脚本,覆盖短视频(7-60秒)到中长视频(1-30分钟)全时长。短视频:Hook 变体评分、分秒计时、字幕文案、封面方案。中长视频:留存率优化、节奏中断点、前向钩子、章节结构。

适用于抖音、视频号、小红书视频、B站、YouTube 等平台。当用户说"视频脚本"、"短视频脚本"、"抖音脚本"、"B站脚本"、 "视频号脚本"、"竖版视频"、"Reel 脚本"、"写个视频文案"时使用。和 video-strategy 的区别:video-strategy 做视频内容规划和系列策划, video-script 写具体某一条视频的脚本。

视频脚本生成

根据目标时长自动适配短视频或中长视频模式,生成留存率优化的结构化脚本。

输入

字段必填说明示例
主题是视频主题"为什么 Rust 正在替代 C++"
目标时长是秒数或分钟数30 秒 / 10 分钟
平台否抖音/视频号/小红书/B站(默认按时长推断)抖音
内容类型否科普/教程/评测/种草/解说/杂谈科普
核心要点是要覆盖的关键信息内存安全、性能…
调性否专业/轻松/犀利/对话感(默认:对话感)轻松

模式自动判定

时长模式典型平台关键指标
7-15 秒短视频·极速抖音/视频号3 秒完播率
15-60 秒短视频·标准抖音/视频号/小红书完播率、DM 转发、收藏
1-5 分钟中视频视频号/抖音/B站5 秒留存、互动率
5-30 分钟长视频B站/YouTube30 秒留存、播放完成率

语速基准:中文约 250 字/分钟。


短视频模式(≤60 秒)

Step 1 — Hook 设计(3 个变体)

从 5 种 Hook 类型中选 3 个,各生成一个变体:

类型适用场景示例
好奇缺口冷知识、反直觉"你每天做的这件事其实在伤害你"
模式打断反常规、挑战认知"忘掉你以前学的所有XX"
身份触发精准受众"如果你是XX,这条一定要看完"
痛点共鸣真实困扰"明明很努力了还是没效果?"
权威背书数据/研究支撑"最新研究发现:XX 竟然是错的"

每个 Hook 按 4 维度评分(每项 1-5,满分 20):好奇强度、打断效果、身份触发、3 秒清晰度。选最高分作为主 Hook。

Step 2 — 分秒脚本

按时长压缩结构:

时长结构
7-15 秒Hook(0-2s) + 核心价值(2-10s) + 收尾(10-15s)
15-30 秒Hook(0-3s) + 痛点(3-8s) + 方案(8-20s) + 收尾CTA(20-30s)
30-60 秒Hook(0-3s) + 痛点(3-8s) + 方案(8-40s) + 洞察+CTA(40-60s)

脚本格式:

[0-3s] HOOK
口播: "..."
字幕: "..."
画面: [描述]

[3-8s] 痛点
口播: "..."
画面: [描述]

每句 ≤15 字,口语化,加括号注释(停顿/强调/表情)。

Step 3 — caption + 封面

caption:100-300 字,Hook 变体开头(不重复视频 Hook),DM 转发 > 收藏 > 点赞。 hashtags:3-5 个垂直标签,不用泛标签。 封面:3-5 字大标题 + 画面描述 + 表情。

Step 4 — 质量评分(满分 100)

维度权重检查点
Hook 强度25好奇缺口、打断效果、3 秒清晰度
内容质量25价值密度、结构、痛点-方案清晰度
caption+CTA20长度 100+字、转发型 CTA、Hook 变体
格式合规159:16 安全区、时长匹配、封面
算法信号15收藏/转发优化、原创性

≥80 分交付,<60 分返工后重评。


中长视频模式(>60 秒)

留存率优化的详细方法(节奏中断点 / 前向钩子 / 章节结构 / 留存曲线)见 references/retention-scripting-guide.md。

Step 1 — 结构计算

根据目标时长分配各段:

  • Hook:0:00-0:30(短视频缩短到 0:00-0:10)
  • 开场:0:30-2:00
  • 首次 CTA:约 25% 处
  • 留存再拉回:约 60% 处
  • 结尾:最后 60 秒
  • 目标字数 = 时长(分钟) × 250

Step 2 — 写 Hook(三段式)

阶段时间目标
抓眼0-5s全片最重要的一句话,不加片头
承诺5-15s看完能获得什么,具体可感知
悬念15-30s不看会损失什么

Step 3 — 内容段落

每段结构:节奏中断 → 正文 → 微总结 → 前向钩子。 节奏中断每 60-90 秒一次(短视频每 15-30 秒),类型:【镜头切换】【画面】【音效】【数据冲击】。

Step 4 — CTA 与结尾

  • 首次 CTA(25% 处):软性、对话式、10-15 秒
  • 留存再拉回(60% 处):"接下来是最关键的部分"
  • 结尾 CTA:硬性号召 + 下期预告,不说"感谢观看"

Step 5 — 留存风险标注

扫描全稿,在危险区标 ⚠️ 警告(至少 3 处)+ 应对方案。

输出格式

产物写入 outputs/。包含:

  • 脚本元数据(主题/时长/平台/字数)
  • 完整分段脚本(含时间码、口播、字幕、画面提示)
  • 节奏中断日志(时间戳/类型/说明)
  • 留存风险地图(中长视频)/ 质量评分(短视频)
  • 剪辑备注

质量检查

  • 字数与时长匹配(250 字/分钟,±10%):用脚本判定,不靠估算。把全部口播文案(去掉时间码、画面提示等非口播行)喂给 python3 skills/shared/scripts/wordcount.py check --target <时长分钟×250> --tolerance 0.1(stdin 传入),退出码 0 = 达标;非 0 时脚本给出「还需增/删 X 字」,据结果增删口播后重跑,直到通过。
  • Hook 完整(短视频 3 变体评分;中长视频三段式)
  • 节奏中断频率达标
  • CTA 位置正确
  • 全稿口语化,短句,不像书面文
  • 结尾有能量,不含收尾废话

Profile 感知

  • 有 Profile:读取 platform 锁定平台、audience 调整用语、tone 匹配风格、cta_style 使用惯用话术
  • 无 Profile:默认按时长推断平台,对话感调性
