# VTSuperResolutionScalerParameters

An object that contains both input and output parameters that the super-resolution processor needs to run on a frame.

```
class VTSuperResolutionScalerParameters
```

## Overview

Use this object in the `processWithParameters` call of the `VTFrameProcessor` class. The output parameter for this class is `destinationFrame`, where the processor returns the output frame (as `VTFrameProcessorFrame`) back to you once `processWithParameters` completes.

`VTSuperResolutionScalerParameters` are frame-level parameters.

## Topics

### Creating a parameters object

[`-  initWithSourceFrame:previousFrame:previousOutputFrame:opticalFlow:submissionMode:destinationFrame:`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters/init(sourceFrame:previousFrame:previousOutputFrame:opticalFlow:submissionMode:destinationFrame:))

Creates a new super-resolution scaler parameters instance.

### Inspecting the parameters

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

Current source frame, which must be non `nil`.

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

Previous source frame in presentation time order, which is `nil` for the first frame.

[`previousOutputFrame`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters/previousOutputFrame)

Previous output frame in presentation time order, which is `nil` for the first frame.

[`opticalFlow`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters/opticalFlow)

Optional object that contains forward and backward optical flow with the previous frame.

[`destinationFrame`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters/destinationFrame)

Destination frame that contains user-allocated pixel buffer that receives the results.

[`submissionMode`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters/submissionMode-swift.property)

Ordering of the input frames in this submission relative to the previous submission.

[`SubmissionMode`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters/SubmissionMode-swift.enum)

Indicates the order of input frames.
