# referenceSourceAssetTracks

Controls whether the color and audio tracks in the output asset reference the source asset
or embed a copy of its sample data.

```
var referenceSourceAssetTracks: Bool { get set }
```

## Discussion

When YES, the output asset references the color and audio sample data from the
source asset. This keeps the intermediate file small, but the output asset will not be
portable — it depends on the source asset remaining at its original location.

When NO (the default), the color and audio sample data is copied into the output asset, making it
self-contained and portable at the cost of roughly doubling the storage required.

The disparity and metadata tracks are always embedded regardless of this setting.
