# 长剪短(gtrk-long2short)

把用户的一条长视频,用 `gtrk` CLI 跑通「**本地抽音频/720p 代理(毛片永不上传)** → 云端语义选段+跳剪(可选分屏)→ 逐 clip 拉回 gtrk/剪映/PR 三方工程」,再把产物目录回给用户。**CLI 是手、你是脑。**

> 与智能剪口播(gtrk-oralcut)同一心智模型;差异是**一次任务出 N 条短片**,各自一份工程组落 `clip{i}/` 子目录。

> **⚠<U+FE0F> 源片是「直播回放」?先去 `/gtrk-live-slicing`。** 直播回放有本 skill 不处理的场景约束:
> **单次提交超 2 小时会被服务端直接拒**(`6019`,必须先分段)、选题必须经用户确认再出工程、
> 按画面形态分段配分屏、源片自带的烧录贴片如实告知不动它。那张图纸编排完这些,
> 最终仍然回到本 skill 的命令上——**它是场景图纸,这里是链路手册,配合用不冲突。**

> **⚠<U+FE0F> 先确认用户要工程还是要成片。** 本 skill 是**粗剪**——出的是**可编辑工程**(gtrk + 剪映 + PR),
> 给人二次精修用,毛片不上传。如果用户只要**能直接发布的成片**、不打算再剪,那该走**精剪**:
> `gtrk tool video_long2short_pro`(走 `/gtrk-tools`,整片上传、云端渲染、计费约为粗剪两倍)。
