# 设置面板

You need to open the settings panel first. The player has four settings by default: `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,
});
```
