# VTLowLatencyFrameInterpolationParameters

An object that contains both input and output parameters that the low-latency frame interpolation processor needs.

## Declaration

```swift
class VTLowLatencyFrameInterpolationParameters
```

## Overview

Overview Use this object in the processWithParameters call of VTFrameProcessor class. VTLowLatencyFrameInterpolationParameters are frame-level parameters.

## Topics

### Creating a parameters object
