# Design B-roll / 设计 B-roll ## When to use / 何时使用 After script lock, before any B-roll render. Outputs a render plan the per-type skills consume. 脚本定稿后、渲染前。生成各类型 B-roll 的渲染计划。 ## Inputs / 输入 - `workspace/script/script.full.md` (with `[BROLL: ...]` cues). - `workspace/script/segments.index.json`. ## Output / 输出 - `workspace/broll/plan.json`: `[{id, type, start_s, dur_s, segment_id, prompt, assets[]}]`. ## Steps / 步骤 1. Parse `[BROLL: ...]` cues; infer type from keywords (`chart` → data-viz, `flow` → flowchart, etc.). 2. For each cue, set duration ≤ 8 s; pad to nearest sentence boundary. 3. Distribute density target ≈ 1 cue per 15 s; warn if exceeded. 4. Emit plan JSON. ## Examples / 示例 ``` claude run design-broll ``` ## Failure recovery / 失败回退 - If no `[BROLL]` cues exist, generate plausible ones from section headings and mark `auto: true`. - If type unclear, default to `concept-diagram`.
