用自然语言指令剪辑视频：裁剪、拼接、变速、跳切去静音、文字覆盖、横竖比转换、抽帧封面、转 GIF、压缩、加 BGM/水印，基于 ffmpeg。当用户说"剪视频""裁剪视频""拼接视频""视频变速""去静音""视频加文字""视频转GIF""压缩视频""加BGM/水印"时使用。本 SKILL 做单条视频的通用剪辑；智能画幅转换用 video-reframe，长视频切片用 clipify/video-highlights，从 0 生成用 ai-video-gen。.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 视频剪辑

用自然语言指令做通用视频处理。所有操作都调用共享脚本
`skills/shared/scripts/video_ops.py`（subprocess 封装 ffmpeg/ffprobe），
**不要现场手拼 ffmpeg 命令**——脚本已处理音画同步、字体路径、编码默认值、
错误捕获等易错点。

> 从项目根目录运行。脚本相对路径：`skills/shared/scripts/video_ops.py`。
> 每个子命令都支持 `-h` 查看参数。

## 输入

- 视频文件路径 + 操作描述（用户没给路径就问）
- 可选：目标平台/比例/时间段等参数

## 输出

处理后的视频/图片，存到 `outputs/主题名/`。脚本会打印 `✅ <路径> (大小)`。

## 与 clipify 的边界

- **clipify** = 长视频智能切片 + 人脸追踪 pan + 逐字字幕烧录的**特化流程**。
  需要"从长视频找精彩片段做成竖版短视频带字幕"时用它。
- **video-editing（本 SKILL）** = 通用剪辑处理。单点操作或自由组合时用它。
  不做人脸追踪、不做字幕烧录（那是 clipify）。

## 子命令速查

先 `python skills/shared/scripts/video_ops.py info -i <视频>` 看清源信息，再操作。

| 子命令 | 用途 | 关键参数 |
|--------|------|----------|
| `cut` | 按起止时间裁剪 | `--start --end`/`--duration`，`--reencode` 精确裁 |
| `concat` | 多段拼接 | `--mode demuxer`(同参数无损)/`filter`(异参数统一) |
| `speed` | 变速（音画同步） | `--factor 2.0` |
| `silence-cut` | 检测静音并去除（跳切） | `--noise -30 --min-silence 0.5 --pad 0.05`（别名 `mute-cut`） |
| `text` | 文字覆盖 | `--text --position --fontsize --color --start --end --box` |
| `aspect` | 横竖比转换 | `--ratio 9:16 --mode pad`(补边)/`crop`(裁切) |
| `frame` | 抽帧做封面 | `--time 00:00:03 --width` |
| `gif` | 转 GIF | `--start --end --fps 12 --width 480` |

How to install

The exact contents, by fingerprint

mdr add zju-real/easel/video-editing@sha256:7b9326f76186c853

The line at the top of this page pins the label git:20261012.0d53744, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
