# VTSuperResolutionScalerParameters.SubmissionMode

Indicates the order of input frames.

```
enum SubmissionMode
```

## Overview

When submitting [`VTSuperResolutionScalerParameters`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters) to the processor, you need to provide one of these values based on
how the input frames are related to each other.

Use [`VTSuperResolutionScalerParameters.SubmissionMode.sequential`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters/SubmissionMode-swift.enum/sequential) to indicate that the current submission follows
presentation time order without jumps or skips, when compared to previous submissions. This value provides better
processor performance than other values.

Use [`VTSuperResolutionScalerParameters.SubmissionMode.random`](/documentation/VideoToolbox/VTSuperResolutionScalerParameters/SubmissionMode-swift.enum/random) to indicate that the current submission has no relation
to the previous submission. Typically, this indicates a jump or skip in the frame sequence. The processor clears
internal caches when it receives this value in `VTFrameProcessor/processWithParameters` function call.
