# addMovieHeaderToDestination

The new movie header overwrites any existing movie header.

## Declaration

static var addMovieHeaderToDestination: AVMovieWritingOptions { get }
```

## Discussion

Discussion Only an existing movie header is overwritten, all other data is preserved. If the destination file is empty, a file type box is created at the beginning of the file.
