# VTLowLatencyFrameInterpolationParameters

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

```
class VTLowLatencyFrameInterpolationParameters
```

## Overview

Use this object in the `processWithParameters` call of `VTFrameProcessor` class.

`VTLowLatencyFrameInterpolationParameters` are frame-level parameters.

## Topics

### Creating a parameters object

[`init(sourceFrame:previousFrame:interpolationPhase:destinationFrames:)`](/documentation/VideoToolbox/VTLowLatencyFrameInterpolationParameters/init(sourceFrame:previousFrame:interpolationPhase:destinationFrames:))

### Inspecting the parameters

[`sourceFrame`](/documentation/VideoToolbox/VTLowLatencyFrameInterpolationParameters/sourceFrame)

Source frame that you provided when creating the low-latency frame interpolation parameters object.

[`previousFrame`](/documentation/VideoToolbox/VTLowLatencyFrameInterpolationParameters/previousFrame)

Previous frame that you provided when creating the low-latency frame interpolation parameters object.

[`interpolationPhase`](/documentation/VideoToolbox/VTLowLatencyFrameInterpolationParameters/interpolationPhase-886vi)

[`destinationFrames`](/documentation/VideoToolbox/VTLowLatencyFrameInterpolationParameters/destinationFrames)

Array of destination frames that you provided when creating the low-latency frame interpolation parameters object.
