# PHVideoRequestOptionsDeliveryMode.fastFormat

Photos provides whatever quality of video can be most quickly loaded.

## Declaration

```swift
case fastFormat
```

## Discussion

Discussion When the isNetworkAccessAllowed property is true, the fast option provides a version of the video asset suitable for streaming from iCloud over a low-quality connection—for example, an MP4 video with 360p resolution. If a higher-quality version is already cached on the device, Photos provides that video instead.
