Transition Design

分析相邻片段边界帧，设计最优转场效果，输出转场设计指令。使用场景：所有片段已处理完成、需要设计片段间转场。避免场景：片段处理未完成、缺少素材Handle信息

Security Scan

The skill's requested resources and instructions match its stated purpose (designing frame-level transitions) and it does not request unrelated credentials, installs, or external endpoints.

Purpose & Capability

Name/description (设计转场) align with the content: the skill only needs clip metadata, frame-level visual analysis, and the included KBs. No unrelated binaries, env vars, or config paths are required.

Instruction Scope

SKILL.md stays within scope (analyze adjacent clip boundary frames, validate handles, choose transition type, emit design instructions). It references the provided reference docs only. One operational ambiguity: it assumes access to '粗剪数据' and frame-level visual content (motion vectors, lighting, composition) but does not specify how those are supplied — this is an operational requirement, not a security mismatch.

Install Mechanism

Instruction-only skill with no install spec and no code files. Nothing is written to disk or downloaded during install.

Credentials

No environment variables, credentials, or config paths are requested. The skill only needs clip metadata and frame analysis inputs, which are proportional to its purpose.

Persistence & Privilege

always is false and the skill does not request elevated or permanent presence or modify other skills. Autonomous invocation is allowed (platform default) and is not combined with other red flags.

Assessment

This skill appears internally consistent and low-risk: it only contains guidance and two reference KB files for calculating handles and selecting transitions. Before using it, ensure you supply the required clip metadata and frame-level assets (or another skill that provides them). Don’t grant unrelated credentials or broad filesystem access to the agent on behalf of this skill. If you plan to automate frame analysis, verify which tool will provide motion/lighting data and that those tools are trusted.

When to use

使用此 skill 当：

• 所有片段已处理完成
• 需要设计片段间转场

避免使用当：

• 片段处理未完成
• 缺少素材Handle信息

Core principles

• Golden Rule：转场不能"吃掉"叙事内容帧，粗剪边界是绝对边界
• Handle不足时强制硬切
• 默认使用硬切，除非叙事需要其他转场

Workflow

Step 1: 帧级分析 获取三个关键数据点：

• 粗剪数据：Clip A和Clip B的入点/出点及可用Handle
• 视觉内容：边界帧的运动矢量、光线、构图
• 分镜意图：脚本中建议的转场类型

Step 2: Handle验证 查阅 handle-logic-kb.md 验证转场可行性：

• 计算 (Tail Handle + Head Handle)
• 如果 < 所需转场帧数 → 强制Hard Cut

Step 3: 策略选择 查阅 transition-kb.md 根据叙事意图和技术可行性选择转场类型：

• Hard Cut: 默认选择，用于连续动作、对话，或Handle不足时
• Dissolve: 用于时间流逝或地点变换
• Wipe/Other: 特殊叙事需求

Step 4: 生成转场设计指令

• Decision Status:
  • Validation Result: Following / Adapting / Overriding
  • Rationale: 解释与脚本意图的差异（如有）
• Transition Strategy:
  • Type: 最终转场类型
  • Timing Mode: Center Cut / Start Cut / End Cut
• Frame-Level Specifications:
  • Total Duration (Frames)
  • Handle Consumption: A的尾部延伸帧数 / B的头部延伸帧数
• Effect Parameters:
  • Interpolation: Linear / Ease-In / Ease-Out
  • Visual Attributes: 方向、边缘柔和度等

Step 5: 输出转场设计 组装 transition_designs
