# 设置面板

## 内置

须先打开设置面板，然后自带四个内置项：`flip`, `playbackRate`, `aspectRatio`, `subtitleOffset`

<div className="run-code">▶ Run Code</div>

```js{4}
var art = new Artplayer({
    container: '.artplayer-app',
    url: '/assets/sample/video.mp4',
	setting: true,
    flip: true,
    playbackRate: true,
    aspectRatio: true,
    subtitleOffset: true,
});
```
