Metadata Handling

This appendix describes how metadata is handled when QuickTime imports other file formats. (For more information about metadata, refer to “Overview of the File Format” and “Compressed Movie Resources”).

These formats are grouped into the following categories and sections:

Each section includes a table with specific details on the following, where applicable:

The format supported by QuickTime––for example, the movie import component or the graphics import component
The Macintosh file type––for example, 'Mp3 '
File name extensions––for example, .mp3
Specific details for metadata handling––for example, all Microsoft-defined “tombstone” data is transferred to the imported movie’s user data. metadata fields that have QuickTime equivalents are mapped as follows.
Software required––for example, QuickTime 3 or later

Digital Video File Formats

OpenDML and other AVI files	Description
Supported by	Movie import component
Macintosh file type	`'VfW '`
File name extensions	`.avi`
metadata handling	All Microsoft-defined “tombstone” data is transferred to the imported movie’s user data. metadata fields that have QuickTime equivalents are mapped as follows: `'ICOP'` maps to `kUserDataTextCopyright`, `'ISBJ'` maps to `kUserDataTextInformation`, `'INAM'` maps to `kUserDataTextFullName`, `'ICRD'` maps to `'©day'`, `'IMED'` maps to `'©fmt'`, `'ISRC'` maps to `'©src'`.Where no QuickTime equivalent exists, the metadata item’s four-character code is modified by replacing the initial `I` with the symbol `©`. All other characters remain unchanged.
Software required	QuickTime 3

MPEG 1 layer 3	Description
Supported by	Movie import component
Macintosh file type	`'Mp3 '`, `'SwaT'`, `'MPEG'`, `'PLAY'`, `'MPG3'`,`'MP3 '`
File name extensions	`.mp3, .swa`
Metadata handling	Metadata from ID3v1-style MP3 files is imported into the QuickTime movie.Title maps to `kUserDataTextFullName`, artist maps to `'©ART'`, album maps to `'©alb'`, year maps to `'©day'`, comment maps to `'©cmt'`, and track number maps to `'©des'`.
Software required	QuickTime 4

WAV	Description
Supported by	Movie import component
Macintosh file type	`'WAVE'`, `'.WAV'`
File name extensions	`.wav`
Metadata handling	All Microsoft-defined “tombstone” data is transferred to the imported movie’s user data. metadata fields that have QuickTime equivalents are mapped as follows: `'ICOP'` maps to `kUserDataTextCopyright`, `'ISBJ'` maps to `kUserDataTextInformation`, `'INAM'` maps to `kUserDataTextFullName`, `'ICRD'` maps to `'©day'`, `'IMED'` maps to `'©fmt'`, `'ISRC'` maps to `'©src'`.Where no QuickTime equivalent exists, the metadata item’s four-character code is modified by replacing the initial `I` with the symbol `©`. All other characters remain unchanged.
Software required	QuickTime 2.5 or later

FlashPix	Description
Supported by	Graphics import component
Macintosh file type	`'FPix'`
File name extensions	`.fpx`
Metadata handling	Information about copyright, authorship, caption text, content description notes, camera manufacturer name, camera model name are transferred to `kUserDataTextCopyright`, `kUserDataTextArtistField`, `kUserDataTextFullName`, `kParameterInfoWindowTitle`, `kParameterInfoManufacturer`, `kUserDataTextMakeField` user data items, respectively.
Formats supported	1.0
Software required	QuickTime 4

GIF	Description
Supported by	Graphics import component
Macintosh file type	`'GIFf'`, or`'GIF '`
File name extensions	`.gif`
Metadata handling	The GIF comment field is transferred to the `kUserDataDateTextInformation` user data item.
Software required	QuickTime 2.5 or later

JFIF/JPEG	Description
Supported by	Graphics import component
Macintosh file type	`'JPEG’`
File name extensions	`.jpg`
Metadata handling	The JFIF comment field is transferred to the imported Movie’s user data in the `kUserDataTextInformation` field.
Software required	QuickTime 2.5 or later

Photoshop	Description
Supported by	Graphics import component
Macintosh file type	`'8BPS'`
File name extensions	`.psd`
Metadata handling	Photoshop files store their metadata based on the IPTC-NAA Information Interchange Model and Digital Newsphoto Parameter Record. This information is transferred into the importer Movie’s user data. The entire ITPC-NAA record is placed into a user data item of type `'iptc'`. In addition, those metadata items which are defined by QuickTime are mapped directly to QuickTime types as follows: 116 to `kUserDataTextCopyright`, 120 to `kUserDataTextInformation`, 105 to `kUserDataTextFullName`, 55 to `'©day'`, 115 to `'©src'`.
Software required	QuickTime 2.5 or later. QuickTime 3 is required for metadata handling.

QuickTime Image File	Description
Supported by	Graphics import component
Macintosh file type	`'qtif'`
File name extensions	`.qtif`, `.qif`, `.qti`
Metadata handling	Metadata that is stored in `quickTimeImageFileMetaDataAtom` atom is copied directly to the Movie’s user data.
Formats supported	All
Software required	QuickTime 2.5 or later

TIFF	Description
Supported by	Graphics Import Component
Macintosh file type	`'TIFF'`
File name extensions	`.tif`, `.tiff`
Metadata handling	Extracted from standard tags and from IPTC block
Software required	QuickTime 3 or later

Animated GIF	Description
Supported by	Movie import component
Macintosh file type	`'GIFf'`
File name extensions	`.gif`
Metadata handling	The GIF comment field is transferred to `kUserDataTextInformation` user data item.
