System and method for media production
First Claim
1. A computer-implemented method of constructing output data constituting a music-based audiovisual media production for display on an audiovisual display device, from input data including both visual media and musical media, the method including the steps of:
- (a) performing signal analysis upon the musical media to generate a series of music descriptor values, said signal analysis being performed upon the musical media at a micro timescale including beats and sub-beats, each of the music descriptor values indicating the presence of a perceptually-significant characteristic of the musical media at a corresponding time in the music, said music descriptor values including edit hints, each edit hint corresponding to a certain time in the input music data, said edit hints including edit hints corresponding to respective times between said beats;
(b) receiving from a user an input indicative of the values of a set of editing parameters;
(c) defining segments of the visual media according to said series of music descriptor values and said set of editing parameters; and
(d) concatenating a plurality of said segments of the visual media.

Abstract
An editing system is proposed for automatically, or semi-automatically, editing input data to generate output production. The input material is annotated by, or analyzed to derive, a set of media descriptors which describe the input material and which are derived from the input material. The style of editing is controlled using style data which is optionally derived from a user. The input material may include any or more of motion video, still images, music, speech, sound effects, animated graphics and text. The style data and the descriptors are used to generate a set of operations which, when carried out on the input data, generate an edited output production.

42. A computer system comprising a processor and a data storage device,
the data storage device storing program instructions operable by the processor to construct output data constituting a music-based audiovisual media production for display on an audiovisual display device from input data including both visual media and musical media, by performing the steps of: -
(a) performing signal analysis upon the musical media to generate a series of music descriptor values, said signal analysis being performed upon the musical media at a micro timescale including beats and sub-beats, each of the music descriptor values indicating the presence of a perceptually-significant characteristic of the musical media at a corresponding time in the music, said music descriptor values including edit hints, each edit hint corresponding to a certain time in the input music data, said edit hints including edit hints corresponding to respective times between said beats; (b) receiving from a user an input indicative of the values of a set of editing parameters; (c) defining segments of the visual media according to said series of music descriptor values and said set of editing parameters; and (d) concatenating a plurality of said segments of the visual media.

43. A computer-implemented method for editing input data including input visual data and input music data to form a music-based audiovisual media production for display on an audiovisual display device and including output visual data, the method including the steps of:
-
analyzing the input music data to derive one or more descriptors including music descriptors, said music descriptors characterizing each of a plurality of portions of the input music data at a micro timescale including beats and sub-beats; defining edit preferences for controlling the editing of the input data; using said descriptors and said edit preferences to generate a set of editing decisions, the set of editing decisions specifying a set of editing operations to be performed on said input data; and generating said music-based audiovisual media production by performing said set of operations upon said input data; wherein said music descriptors include edit hints, each hint corresponding to a certain time in the input music data and indicating a perceptually-significant characteristic of a portion of the input music data, said edit hints including edit hints corresponding to respective times between said beats.
