# AVCaptureTimecode

This structure represents a timecode, adhering to SMPTE standards, which define precise time information and associated timestamps for video or audio synchronization.

## Declaration

```swift
struct AVCaptureTimecode
```

## Overview

Overview This structure corresponds to the SMPTE 12M-1 Linear Timecode (LTC) format, widely used for professional video and audio synchronization.
