# sessionPreset

A preset value that indicates the quality level or bit rate of the output.

```
var sessionPreset: AVCaptureSession.Preset { get set }
```

## Discussion

Specify a preset value to configure a capture session’s format and settings. The default preset is [`high`](/documentation/AVFoundation/AVCaptureSession/Preset/high), which produces high-quality video and audio output, but you can specify any preset value that returns <doc://com.apple.documentation/documentation/Swift/true> for a call to [`canSetSessionPreset(_:)`](/documentation/AVFoundation/AVCaptureSession/canSetSessionPreset(_:)).

You can set this value while the session is running.
