Method and apparatus for automatically creating a movie
View Patent ↗Methods and systems for automatically creating a movie of computer selected video scenes accompanied by music are disclosed. Methods or systems consistent with the invention may synchronize the video scene changes with the onsets of beats in the music. Methods or systems consistent with the invention may also offer a user of the computer program product a choice of video styles by which the movie may be characterized when viewed by the user.
1. A computer-implemented method of making a movie comprising:
receiving digital music content;
receiving user-provided digital video content;
offering a selection of video styles to a user;
receiving a user-selected video style, the video style comprising preset values of variables that define the visual characteristics of the movie;
providing a set of onset times and a corresponding set of beat strength values of beats at a fundamental beat frequency in the digital music content;
choosing from the set of onset times, stop time for one or more video scenes to be played in the movie using at least one of the preset values of the variables from the video style and the beat strength values corresponding to the onset times;
selecting from the user-provided digital video content, one or more video scenes to match in duration the duration between the scene's start and stop times;
creating a list of selected video scenes for synchronized playback with the digital music content, wherein a plurality of the selected video scenes change in synchronization with a subset of onset times of beats in the digital music content.
2. The method of claim 1 , wherein the preset values of the variables define at least one of the following characteristics of a video: video scene duration, video scene order, number of transitions between scenes, transition techniques used, number of scenes with filters, filter techniques used, number of scenes with playback speed other than normal, video playback speed.
3. The method of claim 1 ,
wherein choosing a stop time comprises:
determining a first scene ending time and a second, later scene ending time using at least one variable from the video style; and
choosing the onset time corresponding to the greatest beat strength value between the first scene ending time and the second, later scene ending time.
4. The method of claim 1 , wherein choosing a stop time comprises: determining a target scene stop time using at least one variable from the video style; and choosing the beat onset time nearest to the target scene stop time.
5. A computer-readable medium of instructions that when executed by a processor perform a method, the method comprising:
receiving digital music content;
receiving user-selected digital video content;
offering a selection of video styles to a user;
receiving a user-selected video style, the video style, comprising preset values of variables that create the visual characteristics of the movie;
providing a set of onset times and a corresponding set of beat strength values of beat at a fundamental beat frequency in the digital music content;
choosing from the set of onset times, stop time for one or more video scenes to be played in the movie using at least one of the preset values of the variables from the video style and the beat strength values corresponding to the onset times;
selecting from the user-selected video content, one or more video scenes to match in duration the duration between the video scene's start and stop times; and
creating a list of selected video scenes for synchronized playback with the digital music content, wherein a plurality of the selected video scenes change in synchronization with a subset of onset times of beats the digital music content.
6. The computer-readable medium of claim 5 , wherein the preset values of the variable define at least one of the group of characteristics of a video consisting of: video scene duration, video scene order, number of transitions between scenes, transition techniques used, number of scenes with filters, filter techniques used, number of scene with playback speed other than normal, video playback speed.
7. The computer-readable medium of claim 5 ,
wherein choosing a stop time comprises:
determining a first scene ending time and a second, later scene ending time using at least one variable from the video style; and
choosing the beat onset time corresponding to the greatest strength value between the first scene ending time and the second, later scene ending time.
