# init(frameWidth:frameHeight:spatialScaleFactor:)

Creates a new low-latency frame interpolation configuration for spatial scaling and temporal scaling.

```
init?(frameWidth: Int, frameHeight: Int, spatialScaleFactor: Int)
```

## Parameters

`frameWidth`

Width of source frame in pixels.

`frameHeight`

Height of source frame in pixels.

`spatialScaleFactor`

The requested spatial scale factor as an integer. Currently, the processor supports only 2x spatial scaling.

## Discussion

When you configure the processor for spatial scaling, the low-latency frame interpolation processor only supports 2x
spatial upscaling and a single frame of temporal interpolation at a 0.5 interpolation phase.
