# AVProVideoStorage

A class to track and manage pre-allocated storage for high data rate video capture.

```
class AVProVideoStorage
```

## Overview

`AVProVideoStorage` is a singleton that manages system-wide pre-allocated storage used during high data rate video capture
to ensure I/O determinism and sustain high bandwidth captures (e.g. ProRes).
