EMu detects all audio and video formats registered with Windows and makes them available.
The Metadata|Extract Registry entry controls what metadata is copied into EMu.
Whenever an image is derived from a master image in EMu (i.e. a different resolution of the master image), it is possible to copy some or all of the master image's metadata to the derived image. The Metadata|Embed Registry Entry controls what metadata is copied from the master image to the derived image(s).
EMu supports three metadata standards, with a tab provided for each in the Multimedia module:
- EXIF - Exchangeable Image File Format (Version 2.2, April 2002):
- IPTC - International Press Telecommunications Council (IIM Version 4.1, July 1999):
- XMP - Extensible Metadata Platform (Revision September 2005):
When an image is added to the Multimedia module, metadata is extracted from the file and stored on the appropriate tab:
- EXIF supports jpeg and tiff formats
- IPTC supports jpeg, tiff, pict, ps and psd formats
- XMP supports jpeg and tiff formats
