```

## Return Value

Return Value An AVMutableMovie object.

## Discussion

Discussion On initialization, the defaultMediaDataStorage property and any associated mediaDataStorage properties are set to nil. To create an AVMutableMovie from a file and then append sample buffers to any of its tracks, you must first set one of these properties to indicate where the sample data should be written. Use this method to create movies from movie headers that are not stored in files, which can include movies on the pasteboard.
