# VTMotionBlurParameters

This object contains both input and output parameters necessary to run the motion blur processor on a frame.

## Declaration

```swift
class VTMotionBlurParameters
```

## Overview

Overview This object is used in the processWithParameters call of the VTFrameProcessor class. The output parameter is a destinationFrame where the output frame is returned as a VTFrameProcessorFrame back to the caller function once processWithParameters completes. The parameters within VTMotionBlurParameters are frame level parameters.
