# ARConfiguration.VideoFormat

A video size and frame rate specification for use with an AR session.

```
class VideoFormat
```

## Overview

This class is immutable; to set the frame rate and video resolution for an AR session, set your configuration’s [`videoFormat`](/documentation/ARKit/ARConfiguration/videoFormat-swift.property) property to one of the formats in the [`supportedVideoFormats`](/documentation/ARKit/ARConfiguration/supportedVideoFormats) array.

## Topics

### Accessing format information

[`framesPerSecond`](/documentation/ARKit/ARConfiguration/VideoFormat-swift.class/framesPerSecond)

The rate at which the session captures video and provides AR frame information.

[`imageResolution`](/documentation/ARKit/ARConfiguration/VideoFormat-swift.class/imageResolution)

The size, in pixels, of video images captured in the session.

[`isRecommendedForHighResolutionFrameCapturing`](/documentation/ARKit/ARConfiguration/VideoFormat-swift.class/isRecommendedForHighResolutionFrameCapturing)

Determines whether the framework considers a format suitable for high-resolution frame capture.

[`videoHDRSupported`](/documentation/ARKit/ARConfiguration/VideoFormat-swift.class/isVideoHDRSupported)

Determines whether the format supports high dynamic range (HDR).

### Inspecting the video source

[`captureDevicePosition`](/documentation/ARKit/ARConfiguration/VideoFormat-swift.class/captureDevicePosition)

The position of the capture device.

  <doc://com.apple.documentation/documentation/AVFoundation/AVCaptureDevice/Position-swift.enum>

[`captureDeviceType`](/documentation/ARKit/ARConfiguration/VideoFormat-swift.class/captureDeviceType)

The camera that supplies the video format.
