# 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。
