## Declaration

```swift
var isLowLightVideoNoiseReductionSupported: Bool { get }
```

## Discussion

Discussion This property returns true if the connection’s source device’s active format supports low light video noise reduction (see AVCaptureDeviceFormat/isLowLightVideoNoiseReductionSupported) and the connection’s output supports the feature. This value reflects the active configuration and can change as the active format, video stabilization mode, auto video frame rate, or maximum video frame rate changes. See automaticallyEnablesLowLightVideoNoiseReduction for a detailed discussion. This property is key-value observable.
