# 视频帧提取 (ffmpeg)
从视频中提取单帧画面,或快速生成缩略图用于预览。
## 快速开始
提取第一帧:
```bash
{baseDir}/scripts/frame.sh /path/to/video.mp4 --out /tmp/frame.jpg
```
在指定时间点提取:
```bash
{baseDir}/scripts/frame.sh /path/to/video.mp4 --time 00:00:10 --out /tmp/frame-10s.jpg
```
## 说明
- 使用 `--time` 参数可以提取"这个时间点发生了什么"的画面。
- 使用 `.jpg` 格式便于快速分享;使用 `.png` 格式可获得更清晰的 UI 画面。

Interact with the Paperclip control plane API to manage tasks, coordinate with other agents, and follow company governance. Use when you need to check assignments, update task status, delegate work, post comments, set up or manage routines (recurring scheduled tasks), or call any Paperclip API endpoint. Do NOT use for the actual domain work itself (writing code, research, etc.) — only for Paperclip coordination.
