Definitions

  • the present invention relates to a method for the automated and semi-automated creation and editing of digital video movies from digital items found in digital media databases, through the creation of templates which determine the content and the style of the movies.
  • digital video movies have numerous applications. For example, many of these video movies are used as sales presentations by sales personnel to customers from different countries or cultures, or with different backgrounds. Other video movies are used for training different employee groups and the like. In these cases, it is desirable to edit and modify the video movie so that each created version is best suited for the background of each viewer, or for each group of viewers.
  • Another common use of video editing is for the preparation of documentary movies. Some of the same source material may be used in many different documentary movies, and convenient access to the video material is advantageous.
  • the preparation of digital video movies is currently done by the use of programs or software. These programs could be divided into several groups, including software which is used to edit movies, software which manages the information related to the movies and software video technology programs.
  • Editing software programs select clips, sequence them, add to them, or insert text and graphical effects and the like to the clips.
  • Software which handles information describing the media items in the database, such as their lengths, topics, dates and any other useful and pertinent information also provides a link to the media items on their storage media.
  • Software video technology programs capture and play back digital video, thereby providing the ability to add and remove video, sound, text, image and 3D object tracks to the video stream. Examples of such programs include MicrosoftTM DirectXTM and AppleTM QuickTime TM.
  • the product of this movie creation process is a digital file that includes and merges all of the elements used for its creation. The finished movie is essentially impossible to disassemble into the original source components, as they merge together in a way that makes this disassembly either impractical or impossible. Therefore both the video source and the edited movie must be kept and stored, thus increasing the required storage space. This imposes a major burden on the storage devices, as the same source material could be used in many video movies.
  • An object of the present invention is the provision of a software-based method that enables the automated or semi-automated creation, modification and editing of digital video movies from digital data items searched in, and retrieved from, digital media databases. This is done through the use of mathematical structures, specific to each type of video movie, which are called templates.
  • a template includes predefined parameters which are part of the digital video items that are to form the movie, or that affect these items. Some of these parameters are used by a software program for the search and the retrieval of those digital video items, while other parameters are used by that software program for the adaptation of the selected items during editing, leading to flexibility and adaptability in the creation of the video movies.
  • the identifier of the template identifies the at least one video item according to the parameter of the at least one video item.
  • the style parameter determines a style for the at least a part of the video movie. More preferably, the step of assembling the at least one video item and the at least one accessory item further comprises the step of: (i) editing at least one of the at least one accessory item and the at least one video item according to the style of the style parameter in the template. Most preferably, the step of editing at least one of the at least one accessory item and the at least one video item further comprises the step of determining a characteristic of the at least one accessory item selected from the group consisting of a horizontal position, a vertical position, a size, a color and a layer according to the style parameter.

Items of a similar nature are preferably grouped into one of several general groups, such as video clips, graphical items, sound tracks and other groups. All items belonging to a group have the same number and type of parameters, although the values of the parameters vary between items. Some of these values are unique to an item, and are used for the identification of that item and for the distinction between the different items in a group. For example, parameters found in many groups are keyword or keywords, which are also used to choose an item from among others in the database.

Abstract

L'invention concerne un procédé logiciel, qui permet des créations, modifications et montages automatiques de films vidéo numériques à partir d'articles de données numériques recherchés dans et extraits de médiathèques numériques. Le procédé se met en oeuvre au moyen d'outils logiciels, appelés masques, spécifiques à chaque film vidéo. Un masque comprend des paramètres choisis par l'utilisateur en tant qu'éléments des articles de vidéo numérique devant constituer le film ou avoir une incidence sur ces articles. Quelques-uns de ces paramètres sont utilisés par le programme logiciel pour effectuer la recherche et l'extraction desdits articles de vidéo numérique, tandis que d'autres paramètres sont utilisés par le programme logiciel pour adapter les articles choisis au cours du montage, ce qui confère souplesse et adaptabilité à la création des films vidéo.
