# MPMovieNaturalSizeAvailable

Posted when the natural frame size of a movie is first determined or subsequently changes. There is no `userInfo` dictionary.

```
static let MPMovieNaturalSizeAvailable: NSNotification.Name
```

## Discussion

To retrieve the natural frame size for a movie, access the movie player’s <doc://com.apple.documentation/documentation/MediaPlayer/MPMoviePlayerController/naturalSize> property. The movie player whose state has changed is available as the object associated with the notification.
