Abstract

A method for determining a predictability of a media entity portion, the method includes: receiving or generating (a) reference media descriptors, and (b) probability estimations of descriptor space representatives given the reference media descriptors; wherein the descriptor space representatives are representative of a set of media entities; and calculating a predictability score of the media entity portion based on at least (a) the probability estimations of the descriptor space representatives given the reference media descriptors, and (b) relationships between the media entity portion descriptors and the descriptor space representatives.

         7 . The method according to  claim 1 , wherein said additional media portion is selected by a user from a second set of media portions, each media portion being one of the plurality of still images or a portion of the at least one video footage; and wherein this second set is automatically generated based on a decision function. 
     
     
         8 . A method comprising:
 obtaining at least one user-captured footage;   automatically generating, based on a decision function, a sequence of selected media portions; and   allowing a user to apply modification operations to said first sequence of selected media portions, wherein said modification operations comprise selecting a plurality of faces to be emphasized; and   automatically generating, based on the user modifications, an edited audiovisual work that emphasizes the selected faces.   
     
     
         9 . The method according to  claim 8 , further comprising automatically generating, prior to the modification operations by the user, an initial audiovisual work comprising the selected media portions, and wherein the emphasized faces appear more often in the edited audiovisual work than in the initial audiovisual work. 
     
     
         10 . A system comprising:
 a computer processor;   an input device configured to obtain at least one user-captured footage which includes at least one video footage; and   a display device,   wherein the computer processor is configured to automatically generate, based on a decision function, a sequence of selected media portions, wherein at least one of the selected media portions is a subset of the at least one video footage;   wherein the input device is configured to allow a user to apply modification operations to said sequence of selected media portions presented over the display device, wherein said modification operations comprise: changing at least a starting point or an end point of at least one selected media portion of the video footage; and   removing at least one of said selected media portions, and wherein the computer processor is configured to automatically generate, based on the user modifications, an audiovisual work comprising the selected media portions.   
     
     
         11 . The system according to  claim 10 , wherein the one user-captured footage further comprises a plurality of still images, and wherein the selected media portions further comprise one of the plurality of still images. 
     
     
         12 . The system according to  claim 10 , wherein the audiovisual work further comprises at least one transition between two of the selected media portions. 
     
     
         13 . The system according to  claim 10 , further comprising automatically generating, prior to the modification operations by the user, an audiovisual work comprising the selected media portions. 
     
     
         14 . The system according to  claim 10 , wherein said modification operations further comprise adding at least one additional selected media portion. 
     
     
         15 . The system according to  claim 10 , wherein said modification operations further comprise adding at least one additional video media portion being a portion of said at least one user captured video footage. 
     
     
         16 . The system according to  claim 10 , wherein said additional media portion is selected by a user from a second set of media portions, each media portion being one of the plurality of still images or a portion of the at least one video footage; and wherein this second set is automatically generated based on a decision function. 
     
     
         17 . A system comprising:
 a computer processor;   an input device configured to obtain at least one user-captured footage; and   a display device,   wherein the computer processor is configured to automatically generate, based on a decision function, a first sequence of selected media portions,   wherein the input device is configured to allow a user to apply modification operations to said first sequence of selected media portions presented over the display device, wherein said modification operations comprise selecting a plurality of faces to be emphasized, and   wherein the computer processor is further configured to automatically generate, based on the user modifications, an edited audiovisual work that emphasizes the selected faces.
