合成层包装(合成颗粒)——粗剪、B-roll、字幕都定了之后,把选定时间窗做成「合成」:一段时间内的整个画面由一颗代码颗粒接管(画中画拼贴、逐句换画面、对照并排、并列卡片、字幕排版),讲者与 B-roll 作为槽位画进去。三种入口:整片铺满 / 让 AI 判定哪里值得做 / 用户指定区间;候选窗口显示在客户端大纲的 CP 行。当用户想「做合成 / 合成层 / 整片做一下合成包装 / 哪里适合做合成 / 这段做成画中画拼贴 / 11 秒到 32 秒做个合成 / 逐句换画面 / 把字幕排进画面里」时使用本 skill,驱动 `gtrk composite`(plan → review → scaffold → build → lint → lay → bake),别手搓 HTML 铺进工程。

# 合成层包装(gtrk-composite)
把粗剪工程里选定的时间窗做成**合成颗粒**:在这段时间里,整个画面由一颗代码颗粒接管——它决定画面怎么排、何时换、字幕怎么出;讲者与 B-roll 作为**槽位**由客户端把视频画进去。**CLI 是手(定窗口、解析、校验、机检、铺轨),你是脑(判断这段该怎么排、选哪张画面、写场景)。**
> 本 skill 已含你需要的全部信息。命令参数以 `gtrk composite --help` 为准。规则正本:合成颗粒契约在 infra `composite-particle-profile`;`struct_meta.composite` 写方契约在本仓 `composite-command`。
## 你在成片 SOP 的哪一步
最后一层:**粗剪 → 拆分 → B-roll → MG → BGM → 字幕 → 合成 → 出片**。放在最后,是因为这时粗剪、B-roll、字幕都已定,合成颗粒的输入最稳定。但不写死:上游再改,对应颗粒在客户端变「需重渲」,重跑那几颗即可。
前置:
- 有粗剪工程(`<工程>/gtrk/project.gtrk`)和口播转写(`transcript/transcript.json`,新版 `gtrk oralcut` 恒出)。合成按**句**定窗口,没有转写就做不了。
- 字幕最好已上(`gtrk subtitle lay`):合成颗粒可以接管字幕、自己排。
- `gtrk composite --help` 能跑(CLI 版本含本命令族)。
