Methods and systems are described for providing editing tools that allow a user to manipulate media provided by a media content source. Media editing tools may include content analysis tools capable of extracting information from the media content itself, and may include segment identification and editing tools. Editing tools may be created by a user, and stored or shared with other users. Users may be able to specify and customize a set of storage space requirements that impose constraints on the type, quantity and content of stored assets. Automatic storage management tools provide tools with which stored and to-be-stored assets may be transformed in order to maintain satisfaction of storage preferences and requirements.
