# AVDisplayDynamicRange

Describes how High Dynamic Range (HDR) video content renders.

```
enum AVDisplayDynamicRange
```

## Topics

### Creating a dynamic range

[`init?(rawValue: Int)`](/documentation/AVKit/AVDisplayDynamicRange/init(rawValue:))

### Dynamic ranges

[`case automatic`](/documentation/AVKit/AVDisplayDynamicRange/automatic)

Defines an automatic dynamic range. Indicates that the dynamic range will be set automatically.

[`case standard`](/documentation/AVKit/AVDisplayDynamicRange/standard)

Defines a standard dynamic range. Restricts the video content dynamic range to the standard range regardless of the actual range of the video content.

[`case constrainedHigh`](/documentation/AVKit/AVDisplayDynamicRange/constrainedHigh)

Defines a constrained high dynamic range. Allows for constrained High Dynamic Range (HDR) video content which is useful for mixing HDR and Standard Dynamic Range (SDR) content.

[`case high`](/documentation/AVKit/AVDisplayDynamicRange/high)

Defines a high dynamic range. Allows video content to use extended dynamic range if it has dynamic range content.
