Method for making a content sensitive video

Abstract

A method is described for recording a video. The method comprises receiving one or more user content and then providing a 3D virtual world and a virtual camera having one or more parameters. The optimal 3D flight path of the virtual camera is then determined based on the user content and the virtual camera is then allowed to travel along the optimal 3D flight path and to record the video.

1 ) A method for recording a video comprising the steps of:—
 receiving at least one user content; 
 providing a 3D virtual world; 
 providing a virtual camera having at least one parameter; 
 automatically determining the optimal 3D flight path of the virtual camera based on the at least one user content; and 
 allowing the virtual camera to travel along the optimal 3D flight path and to record the video. 
 
     
     
         2 ) The method of  claim 1  further comprising the step of:—
 modifying the at least one parameter of the virtual camera based on the at least one user content. 
 
     
     
         3 ) The method of  claim 1  or  2  wherein the step of determining the optimal 3D flight path comprises the steps of:—
 providing a plurality of 3D flight paths; 
 extracting a plurality of attributes from at the least one user content; 
 optimizing each of the plurality of 3D flight paths based on the plurality of attributes; 
 using an aesthetic function to calculate an aesthetic quality of each of the optimized plurality of 3D flight paths; and 
 selecting the optimized 3D flight path with the highest aesthetic quality as the optimal 3D flight path. 
 
     
     
         4 ) The method of  claim 3  wherein the at least one user content comprises at least one multimedia content and the step of optimizing each of the plurality of 3D flight paths comprises the steps of:—
 selecting at least one segment on the 3D flight path; 
 optimizing the at least one segment based on the plurality of attributes; and 
 deforming the 3D flight path based on the at least one optimized segment. 
 
     
     
         5 ) The method of  claim 4  wherein the step of optimizing the at least one segment comprises the steps of:—
 deriving a plurality of recommended deformations for the at least one segment based on the plurality of attributes; 
 selecting the recommended deformation using dynamic programming; and 
 deforming the at least one segment based on the selected recommended deformation. 
 
     
     
         6 ) The method of  claim 3  wherein the at least one user content comprises an audio track. 
     
     
         7 ) A method for creating a new flight path comprising the steps of:—
 providing a first flight path and a second flight path; and 
 concatenating the first flight path to the second flight path to create a new flight path. 
 
     
     
         8 ) A method for creating a new flight path comprising the steps of:—
 providing a first flight path and a second flight path; 
 extracting a subpath from the first flight path; and 
 concatenating the subpath to the second flight path to create a new flight path. 
 
     
     
         9 ) A computer program for instructing a computer to perform the method of any one of  claims 1  to  8 . 
     
     
         10 ) A computer readable medium having the computer program of  claim 9 .
