Abstract

The system provides for the automatic editing of a video comprised of a plurality of content segments. When two or more content clips are available at a particular moment in time, the system will automatically choose at least a portion of one of the clips pursuant to preference metrics determined by a user. The system contemplates the ability of the user to define specific metrics to control the editing, including frequency of edits, content of content clip, level of activity, and the like. In another embodiment, the system has a plurality of pre-defined editing modes that define various metrics for use in the automatic editing system, including guaranteed participation, speaker-centric, quality of clip, and the like.

Claims

1. A method of automatically editing a plurality of content clips comprising:

in a processing system,

analyzing each content clip and calculating a quality score based on the presence of interesting feature points;

selecting a portion of a content clip for a composite video based on the quality score of the content clip.

2. The method of claim 1 wherein the quality score is calculated on a frame basis of each content clip.

3. The method of claim 2 wherein the quality score is calculated for every frame of a content clip.

4. The method of claim 2 wherein the quality score is calculated for every nth frame of a content clip.

6. The method of claim 2 further including converting each frame to a thumbnail prior to calculating the quality score.

7. The method of claim 6 wherein the quality score is calculated for every thumbnail frame.

8. The method of claim 6 wherein the quality score is calculated for every nth thumbnail frame.

9. The method of claim 8 wherein n equals 3.

10. The method of claim 1 wherein the interesting feature points are those that have the greatest relative movement between frames of a content clip.

11. The method of claim 10 further including assembling the content clips so that at least a portion of each clip is used in the composite video.

12. The method of claim 11 further including defining a minimum amount of each clip that is used in the composite video.

5. The method of claim 5 wherein n equals 3.
