# sourceImage

The current video frame image.

## Declaration

```swift
var sourceImage: CIImage { get }
```

## Discussion

Discussion To apply a Core Image filter to this image, assign it to the inputImage parameter of a CIFilter object, or use a CIImage convenience method such as the applyingFilter(_:parameters:) method. The pixel format for this image is the BGRA8 format (of the kCVPixelFormatType_32BGRA type). Unlike when processing video with the AVAsynchronousVideoCompositionRequest class, the renderContext object’s renderTransform property is already applied to this image.
