# VTFrameProcessorParameters

The base protocol for input and output processing parameters for a frame processor implementation.

```
protocol VTFrameProcessorParameters : NSObjectProtocol
```

## Overview

An instance of a class corresponding to this protocol is passed to [`processWithParameters:error:`](/documentation/VideoToolbox/VTFrameProcessor/processWithParameters:error:) calls and for asynchronous versions of those calls, the same instance is returned in the completion.

## Topics

### Inspecting the parameters

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

A processor frame that contains the current source frame to use for all processing features.

[`destinationFrame`](/documentation/VideoToolbox/VTFrameProcessorParameters/destinationFrame-5suam)

[`VTFrameProcessorFrame`](/documentation/VideoToolbox/VTFrameProcessorFrame) that contains the destination frame for processors which output a single processed frame.

[`destinationFrames`](/documentation/VideoToolbox/VTFrameProcessorParameters/destinationFrames-46ken)

Array of [`VTFrameProcessorFrame`](/documentation/VideoToolbox/VTFrameProcessorFrame) that contains the destination frames for processors which may output more than one processed frame.
