分镜拆解指南

核心定义:分镜段落

一个分镜 = 一个 分镜段落(segment)= 一个视频生成任务。

  • 每个段落时长 8-15 秒,内部承载 2-4 个子镜头
  • 子镜头之间可以切镜:换景别、换角度、换拍摄对象,用硬切衔接
  • 子镜头之间不跨场景:一个段落只发生在一个场景内(scene_id 是段落级绑定)
  • 每个子镜头 2-6 秒,聚焦一个画面单元(一个动作、一个反应、一个特写)

拆分流程(四步)

  1. 调用 read_storyboard_context 读取剧本、角色、场景、道具、已有分镜摘要
  2. 节拍识别:先识别剧本的叙事节拍——剧本中的【开场】【触发】【高潮】【收尾】等标记,或叙事转折点(地点转移、规则揭示、情绪爆发、反转)。节拍边界强制切段,同一节拍内的子镜头优先归入同一段落,不把一条因果链(铺垫-发生-反应)切散到不同段落
  3. 总量锚定:目标总时长 = 剧本字数 ÷ 500字/分钟;段落数 ≈ 目标总时长 ÷ 12秒,允许 ±20% 浮动。不要明显超出或不足
  4. 段落内拆子镜头:按动作切换点、视角切换点、对象切换点切分子镜头,为每个段落补全完整字段后调用 save_storyboards 一次性保存

节奏分层时长

按段落功能确定时长,不要一刀切:

段落类型时长说明
过渡段8-10 秒赶路、空镜、环境建立、转场
叙事段10-15 秒常规剧情推进、对话
爆点段12-15 秒特写、规则揭示、情感爆发、反转;子镜头节奏放慢,单个子镜头可停留 4-6 秒

台词时长下限(硬规则)

段落时长 ≥ 段内台词与旁白总字数(写在 description 中的部分)÷ 4.5字/秒 + 2秒表演余量

装不下的台词必须拆到下一个段落,不允许把演不完的台词塞进一个段落。

镜头要素

  1. 镜头标题:3-5字概括段落核心内容(如"噩梦惊醒")
  2. 时间:具体时分 + 光线描述
  3. 地点:场景完整描述 + 空间布局 + 环境细节
  4. 景别:段落内主导景别;多景别段落写组合,如"中景+特写"
  5. 角度:平视/仰视/俯视/侧面/背面
  6. 运镜:固定/推镜/拉镜/摇镜/跟镜/移镜(段落内不同子镜头可不同)
  7. 画面描述 description:按 【镜头1】…【镜头2】… 逐子镜头描述观众实际看到和听到的内容——画面(谁 + 具体动作 + 肢体细节 + 表情)写在前;该子镜头有台词时以「角色名说:「台词」」写在对应 【镜头N】 内,旁白写「旁白:内容」
  8. 画面结果 result:段落结尾的即时后果 + 视觉细节
  9. 氛围 atmosphere:光线 + 色调 + 声音 + 整体氛围
  10. 时长 duration:段落总时长 8-15 秒,且满足台词时长下限
  11. 场景关联:若能匹配已有场景,必须填写 scene_id
  12. 角色关联:填写 character_ids,绑定当前段落涉及的 0 到多个角色
  13. 道具关联:填写 prop_ids,绑定当前段落出现的关键道具(0 到多个)

场景关联规则

  • 优先使用 read_storyboard_context 返回的 scenes
  • location + time 可明确匹配时,必须回填正确 scene_id
  • 不要凭空生成不存在的场景 ID
  • 如果剧本内容明显落在已有场景中,不要重复创造新场景描述

角色绑定规则

  • character_ids 必须从 read_storyboard_context 返回的角色列表中选择
  • 一个段落可以没有角色,也可以绑定多个角色
  • 只要段落里有明确出场、被看见、发生动作或说话的角色,都应绑定进去
  • 纯环境段落、空镜、物件特写可以传空数组

道具绑定规则

  • prop_ids 必须从 read_storyboard_context 返回的道具列表(props)中选择
  • 道具被角色使用、交接、特写,或在画面中明显可见且对叙事有意义时,必须绑定到该段落
  • 道具特写段落(无角色)也应绑定道具,character_ids 可为空
  • 与剧情无关的背景物品、场景陈设不要绑定;没有道具出现的段落传空数组
  • 绑定的道具会作为视频生成的参考图(白底单品图),保证道具外观跨段落一致

质量要求

  • description 要适合人读,按子镜头详细描述观众实际看到和听到的内容;台词/旁白直接写在对应 【镜头N】 内
  • image_prompt 要突出单帧构图、角色外观、环境和光线(对应段落第一个子镜头)
  • bgm_prompt 和 sound_effect 用简洁短语即可,但不能空泛到只有“紧张”“悲伤”
  • 如需调整,调用 update_storyboard 修改具体段落
