Ember Media Manager is just that: a media manager. Once configured, it let's you fetch, store, and view various details about your media collection. Movies and TV shows are the type of media that Ember can handle.
Ember Media Manager (aka EMM or Ember) is an open source movie and TV Show collections management tool which initially has been created to use with Kodi, but it contains modules for a few media center application, moreover it should virtually support most of the other media center application out there. It empowers home theater enthusiasts to manage and organize their entire movie and TV Show collections. EMM will scrape movie and TV Show information (plot, cast, genre, studio, mpaa certification, etc) from various sites, together with posters, fanart, actor photos and even movie trailers. It also automatically extracts media meta data like resolution, codecs, audio and subtitle streams. EMM can also be used as a standalone movie organizer/cataloger, but the primary aim is to export all the data and images to a format which can then be imported into your favorite media center application. In order to achieve this, EMM stores all data and images in files which are saved next to the media files. Media center applications can pick up those files and import the information to their own internal database.
