Editing Decision Engine

剪辑决策引擎

Follow shared release-shell rules in:
  • postplus-shared
    release-shell rules
Use this skill when the user wants a strong short-form edit plan, not just a script rewrite or a generic video breakdown.
This skill is for post-edit decision making across:
  • A-roll performance
  • B-roll proof footage
  • script meaning
  • beat timing
  • reference-video editing patterns
  • final edit packaging
Do not treat this as a video renderer.
First-version goal:
  • output a high-quality edit decision package
  • not fully automate the final NLE timeline
遵循以下共享发布框架规则:
  • postplus-shared
    发布框架规则
当用户需要的是一份完善的短视频剪辑方案,而非仅仅是脚本改写或通用视频拆解时,使用本技能。
本技能适用于以下场景的后期剪辑决策:
  • A-roll 表演内容
  • B-roll 佐证素材
  • 脚本核心含义
  • 剪辑节奏把控
  • 参考视频的剪辑模式
  • 最终剪辑方案打包
请勿将本工具视为视频渲染器。
第一版目标:
  • 输出高质量的剪辑决策包
  • 不实现最终NLE时间轴的完全自动化

Use For

适用场景

  • planning how to cut a talking-head short
  • deciding where B-roll should appear
  • mapping script beats to visual proof
  • deciding when to stay on A-roll vs cut away
  • translating a reference video into reusable edit patterns
  • packaging a cut plan for Premiere, Final Cut, CapCut, or a human editor
  • 规划访谈类短视频的剪辑方式
  • 确定B-roll的插入位置
  • 将脚本节奏对应到视觉佐证素材
  • 决定何时保留A-roll画面、何时切换镜头
  • 将参考视频转化为可复用的剪辑模式
  • 为Premiere、Final Cut、CapCut或人类剪辑师制定剪辑方案

Trigger Signals

触发信号

Use this skill when the user asks for things like:
  • 这条怎么剪
  • 根据 A-roll 和 B-roll 设计剪法
  • 参考某条视频的剪辑逻辑
  • 按脚本和素材做 post-edit plan
  • 逐句决定哪里贴屏幕、哪里留脸
  • 给我一个时间轴级别的剪辑方案
Do not use this skill when the user only needs:
  • raw video analysis without edit decisions
  • frame extraction without timeline reasoning
  • render generation from image and audio
Route those to:
  • a dedicated visual analysis workflow
  • skills/40-creative/frame-extraction
  • skills/40-creative/video-batch-runner
当用户提出以下类似需求时,使用本技能:
  • 这条怎么剪
  • 根据 A-roll 和 B-roll 设计剪法
  • 参考某条视频的剪辑逻辑
  • 按脚本和素材做 post-edit plan
  • 逐句决定哪里贴屏幕、哪里留脸
  • 给我一个时间轴级别的剪辑方案
当用户仅需要以下服务时,请勿使用本技能:
  • 无剪辑决策的原始视频分析
  • 无时间轴逻辑的帧提取
  • 基于图像和音频生成渲染视频
请将此类需求引导至:
  • 专门的视觉分析工作流
  • skills/40-creative/frame-extraction
  • skills/40-creative/video-batch-runner

Core Principle

核心原则

Do not describe footage only by what appears on screen.
For edit planning, the important question is:
  • what does this shot prove
  • what beat does it support
  • how much attention should it take
  • whether it should lead, support, bridge, or punctuate
The same B-roll clip can be:
  • primary proof
  • support proof
  • transition cover
  • pace reset
  • visual filler
depending on the spoken beat around it.
请勿仅按画面内容描述素材。
对于剪辑规划而言,关键问题是:
  • 这个镜头能佐证什么
  • 它支撑哪个剪辑段落
  • 它需要占据多少注意力
  • 它应起到主导、支撑、过渡还是强调作用
同一段B-roll素材可以是:
  • 核心佐证素材
  • 辅助佐证素材
  • 转场覆盖素材
  • 节奏重置素材
  • 视觉填充素材
具体取决于其对应的旁白段落。

Required Inputs

必填输入

The skill works best when at least these exist:
  • script text or spoken transcript
  • local A-roll file or a reliable description of the A-roll performance
  • local B-roll files or a usable B-roll shot inventory
  • intended output length or target platform
Optional but high-value inputs:
  • one or more reference videos
  • subtitle draft or transcript with timestamps
  • previous edit notes
  • campaign or persona context
If assets are missing, do not pretend the plan is precise.
Instead:
  1. state which decisions are grounded
  2. state which decisions are provisional
  3. produce the strongest plan possible from available evidence
当具备以下至少几项输入时,本技能的效果最佳:
  • 脚本文本或语音转录稿
  • 本地A-roll文件或对A-roll表演内容的可靠描述
  • 本地B-roll文件或可用的B-roll镜头清单
  • 预期输出时长或目标平台
可选但高价值的输入:
  • 一个或多个参考视频
  • 带时间戳的字幕草稿或转录稿
  • 过往剪辑笔记
  • 营销活动或人物设定背景
若缺少部分素材,请勿假装方案精准无误。
应采取以下做法:
  1. 说明哪些决策是有依据的
  2. 说明哪些决策是暂定的
  3. 基于现有素材制定最优方案

Workflow

工作流

1. Lock the edit thesis

1. 确定剪辑核心论点

Before building a timeline, identify:
  • what the video is trying to prove
  • whether it is tutorial-led, viewpoint-led, comparison-led, or proof-led
  • what visual contrast drives the piece
Examples:
  • old fragmented workflow vs in-context workflow
  • tool overload vs cleaner setup
  • annoying to start vs easy to start
在构建时间轴之前,明确:
  • 视频想要佐证的核心观点
  • 视频类型是教程导向、观点导向、对比导向还是佐证导向
  • 驱动视频的视觉反差是什么
示例:
  • 旧的碎片化工作流 vs 场景化工作流
  • 工具过载 vs 简洁配置
  • 启动繁琐 vs 轻松启动

2. Break the spoken content into beats

2. 将旁白内容拆解为剪辑段落

Do not plan edits sentence by sentence only.
Break into edit beats based on:
  • meaning shift
  • emotional shift
  • proof need
  • pace change
Each beat should capture:
  • the spoken line or paraphrase
  • timing if known
  • beat role
  • proof requirement
  • visual demand
请勿仅逐句规划剪辑。
根据以下维度拆解为剪辑段落:
  • 含义转变
  • 情绪转变
  • 佐证需求
  • 节奏变化
每个段落应包含:
  • 旁白原文或意译内容
  • 已知的时长
  • 段落作用
  • 佐证需求
  • 视觉要求

3. Understand assets semantically

3. 从语义层面理解素材

For A-roll:
  • delivery energy
  • pauses
  • emphasis words
  • facial or body moments worth preserving
For B-roll:
  • what it literally shows
  • what it proves
  • where it is strongest
  • how long it can stay on screen before feeling repetitive
For references:
  • what structural pattern is reusable
  • what is surface style only
对于A-roll:
  • 表达的能量感
  • 停顿节点
  • 强调词汇
  • 值得保留的面部或肢体动作
对于B-roll:
  • 画面实际展示内容
  • 能佐证的观点
  • 最具表现力的部分
  • 重复出现前可停留的时长
对于参考视频:
  • 可复用的结构模式
  • 仅为表面风格的元素

4. Decide the cut logic

4. 确定剪辑逻辑

For each beat, decide:
  • stay on A-roll or cut away
  • which B-roll asset to use
  • whether the B-roll is primary or supporting proof
  • overlay length
  • subtitle density
  • whether to use punch-in, hold, montage, J-cut, or L-cut
针对每个段落,决定:
  • 保留A-roll画面还是切换镜头
  • 使用哪段B-roll素材
  • B-roll是核心佐证还是辅助佐证
  • 叠加时长
  • 字幕密度
  • 是否使用特写停留、蒙太奇、J-cut或L-cut

5. Package the output

5. 打包输出内容

Default output should include:
  • edit thesis
  • beat map
  • B-roll assignment table
  • time-ordered edit decisions
  • risks and missing assets
默认输出应包含:
  • 剪辑核心论点
  • 段落映射表
  • B-roll分配表
  • 按时间排序的剪辑决策
  • 风险点与缺失素材

Release-Shell Execution Contract

发布框架执行约定

  • keep edit theses, beat maps, asset notes, and intermediate decision packages under
    <work-folder>/.postplus/editing-decision-engine/
  • keep only final user-facing edit plans outside
    .postplus/
  • start with a bounded first pass on one sequence or one short video before broader edit planning
  • if required inputs such as transcript, A-roll context, or B-roll inventory are missing, stop immediately instead of switching to ad hoc shell glue
  • 将剪辑核心论点、段落映射表、素材笔记和中间决策包保存至
    <work-folder>/.postplus/editing-decision-engine/
  • 仅将最终面向用户的剪辑方案保存至
    .postplus/
    外部
  • 在进行更广泛的剪辑规划前,先针对单个片段或单条短视频完成限定范围的首次处理
  • 若缺少转录稿、A-roll背景或B-roll清单等必填输入,立即停止操作,切勿临时拼凑替代方案

First-Version Boundary

第一版边界

Keep the first version pragmatic.
Prefer:
  • markdown edit plans
  • JSON beat maps
  • B-roll proof tables
  • simple timeline-ready CSV if useful
Do not require in v1:
  • direct XML generation for NLEs
  • automatic cut rendering
  • perfect shot detection
  • automatic motion-design systems
第一版需注重实用性。
优先支持:
  • Markdown格式的剪辑方案
  • JSON格式的段落映射表
  • B-roll佐证表
  • 若有用则提供简单的可导入时间轴的CSV文件
第一版无需支持:
  • 直接为NLE生成XML文件
  • 自动剪辑渲染
  • 精准镜头检测
  • 自动动态设计系统

Output Standard

输出标准

A strong result from this skill should let a human editor start cutting immediately.
Minimum bar:
  • they can tell what the first 3 seconds should do
  • they know where the proof moments land
  • they know which B-roll is essential vs optional
  • they know where the edit should breathe instead of over-cutting
If the output cannot guide a real editor, it is not specific enough.
本技能的优质输出应能让人类剪辑师立即开始剪辑。
最低标准:
  • 明确前3秒的画面内容
  • 明确佐证节点的位置
  • 明确必备与可选的B-roll素材
  • 明确剪辑中需要留白而非过度切割的位置
若输出无法指导实际剪辑,则说明不够具体。
