The table below lists Media Center's default fields. The rows list the available fields, and the columns indicate how the field is defined, and gives a brief explanation of the fields usage or meaning. Where applicable, additional links and field-specific information is also listed. The value for some fields is calculated by Media Center. When possible, the expression used to derive this value is also shown. In some cases, this value may be modified. Beneath a field name is a list of the default Search Keyword(s), if available, which are used for field-specific searching within Media Center.

The Save column indicates if the field is saved in file tags (prior to version 16.0.154, Media Center used the term Stored in the Manage Library Fields dialog). The Search column indicates if the field should be searched when using Media Center's Search area.

Note: Default Search Field. Beginning with MC17, the Default search field setting is not used for stock fields; instead searching fields relies on rules built into the program. Nearly all stock fields are now searched by default. User-defined fields will honor this setting.

Note: Legacy Fields. Some fields are legacy fields, possibly created during an upgrade from a previous version of Media Center. These are noted as "Legacy:" in the Description column. Your Library may not contain these fields.

Note: Some fields are used internally by Media Center to maintain state information, and are not viewable in panes, categories, or the Tag Action Window. These are typically configured through various options and settings dialogs.

Custom Fields

Custom fields may be added with the Add New Field button in the Tools > Options > Libraries & Folders > Manage Library Fields... dialog.

Custom fields can act as library-wide global values, to be used in expressions, as columns, etc.

Custom fields may be calculated expression fields, in that they will be evaluated when used. Storage for calculated fields does not add additional library storage per file, since they are evaluated when used. If configured to be default search fields, calculated fields will produce some search performance penalty in search box suggestions, and possibly other library searches.

Values of calculated fields cannot be stored in file tags.

Tag Import Options

Media Center provides a few options for the importation of tags for some file types. These encoder-specific options are available under Tools > Options > Encoding > Encoder > Encoder settings... (pre-MC18, see Plug-in Manager > Input).

For images and video, Media Center will fill in the Album field with the year of the image or video (if the album field is otherwise empty). This puts a reasonable value there when importing directly from a digital camera. (TBD - should this be moved? Is it comprehensive wrt other types/fields?)

To import non-default file tags into Media Center, first create a custom field named exactly as the physical tag appears in the media file. Subsequent imports, or Update library (from tags) will populate the custom field with the file tag values. A tag dump will show the physical file tags for a single selected file.

Classical Music

The tagging of classical music is unfortunately more complex and standards are lax. See Tagging Classical Music.
