EDITING SYSTEM FOR AUDIOVISUAL WORKS AND CORRESPONDING TEXT FOR TELEVISION NEWS
To address needs of journalists and other editors, an audiovisual editing system associates segments of audiovisual materials with segments of related text. The editing system permits an editor to edit both the audiovisual materials of the segments and to edit the related text. The data structure representing the story includes a list of media segments and a list a text segments and a correspondence among the segments. Each media segment has a type, such as script, SOT and voice, and includes a list of video clips. These data structures enable the editing system to provide a simple and intuitive interface for editing a story, and can be transformed in a straightforward manner into a conventional, multitrack sequence used to represent an audiovisual composition. The editing system automatically defines parameters, such as designating the correct audio tracks, which minimize the chance for errors and speeds the workflow. Automatic ducking of these tracks also can be provided. For media segments with associated script in a corresponding text segment, an estimated time for reading the related script aloud by the newscaster may be determined. This estimated time for reading the text related a script segment may be compared to the actual duration of the audiovisual material of the script segment. The difference in the duration of the audiovisual material and the duration of the related text may be displayed to the editor, making it easier for the editor to match video to a script. Similarly, the duration of voice and SOT clips can be compared to the duration of video clips in a media segment. The difference in the duration of the video clips and the voice and SOT clips may be displayed to the editor, making it easier for the editor to match the video to the audio. Stories can be stored as text documents in a markup language. Data representing the audiovisual segments can be embedded in these stories. The editing system also may be interco ected through a computer network in a newsroom to a variety of other systems including asset management system, shared storage for media and a story database. By having the editing system store stories in the story database and sequences in the asset management system, both sequences and stories are made available to other editing systems.
