Inserts all of the tracks in a specified time range of an asset into a movie.

```
func insertTimeRange(_ timeRange: CMTimeRange, of asset: AVAsset, at startTime: CMTime, copySampleData: Bool) throws
```

## Parameters

`timeRange`

The time range of the asset to be inserted.

`asset`

An [`AVAsset`](/documentation/AVFoundation/AVAsset) object indicating the source of the inserted media. This value can’t be `nil`.

`startTime`

The time in the target movie at which the media is to be inserted.

A Boolean value that indicates whether sample data is to be copied from the source to the destination during edits.

## Discussion
