# synchronizationTimeout

The maximum time interval allowed for source synchronization attempts before timing out.

## Declaration

```swift
var synchronizationTimeout: TimeInterval { get set }
```

## Discussion

Discussion This property specifies the duration, in seconds, that the AVCaptureTimecodeGenerator will attempt to synchronize with a timecode source before timing out if synchronization cannot be achieved. If this threshold is exceeded, the synchronization status updates to reflect a timeout, and your timecodeGenerator(_:transitionedTo:for:) delegate method fires, informing you of the event. The default value is 15 seconds.
