# sparselyInterleavedWithMainMediaData

Indicates that there may be large segments of time without any media data from this track. When mediaDataLocation is set to this value, AVAssetWriter will interleave the media data, but will not wait for media data from this track to achieve tight interleaving with other tracks.

```
static let sparselyInterleavedWithMainMediaData: AVAssetWriterInput.MediaDataLocation
```
