There are three types of documents in Nero CoverDesigner. The distinguishing feature is how the background of the cover elements is created:
Standard Document
The background is created by the user as desired or taken from the template.
Picture Document
A selected picture is used for the background of all cover elements.
Nero AAC Document
The cover art saved in the Nero AAC file (*.mp4) is used for the background of all cover elements.
