Abstract

Automatic editing of video clips detected during the capture of a video data stream. A media editing application identifies video clips as a function of determined property values of each of a series of video frames included in the video. An edit component automatically edits video clips during the capture of the video data stream. A user interface allows the user to view individual video clips during the video capturing process and to define desired transition effects to apply between successive video clips and/or a desired special effect to apply to selected video clips.

4. The computer-readable media of claim 3, wherein the UI component includes a rating control for allowing a user to define a rating for a selected video clip to override the rating assigned by the analysis component, and wherein rating field displays the user defined rating for the video clip being displayed.

5. The computer-readable media of claim 1, wherein the UI component includes a clip queue window comprising a first miniaturized window for displaying a current video clip being transferred from the video source, and one or more second miniaturized windows each representative of a video clip previously transferred from the video source, wherein each of the second miniaturized windows displays a thumbnail representative of a previously transferred video clip, wherein the UI component displays each of the sequenced video clips in a first window, and wherein the UI component is responsive to a user selecting one of the second miniaturized windows to play the video clip corresponding to the selected second miniaturized window in a second window.

6. The computer-readable media of claim 1 further comprising an edit component for applying a default transition effect between successive video clips as a function of the determined differences of the property values between the successive video frames and based on transition selection rules stored in a memory, said transition effect being applied between the successive video clips while the video data stream is being transferred from the video source, and wherein the UI component displays each of the sequenced video clips with the transition effect applied between successive video clips while the video data stream is being transferred from the video source.

7. The computer-readable media of claim 6, wherein applying a transition effect between successive video clips includes applying one or more of the following a dissolve effect, a side wipe effect, a checkerboard effect, a fade effect, a circle effect, a wipe effect, and a line effect.

8. The computer-readable media of claim 6, wherein the UI component includes a transition control for allowing a user to select a desired transition effect to apply between a selected set of successive video clips, and wherein the edit component is responsive to the desired transition effect selected by the user to replace the default transition effect applied between the selected set of successive video clips with the desired transition effect.

9. The computer-readable media of claim 6, wherein the edit component further applies a default special effect to each video clip in the sequenced video clips as a function of the determined the property values of the video frames included in each video clip and based on transition selection rules stored in a memory, and wherein said special effect is applied to each video clip while the video data stream is being transferred from the video source, and wherein the UI component displays the special effect applied to each video clip while the video data stream is being transferred from the video source.

10. The computer-readable media of claim 9, wherein the UI component includes a special effect control for allowing a user to select a desired special effect to apply to a selected video clip, and wherein the edit component is responsive to the desired special effect selected by the user to replace the default special effect applied to the selected video clip with the desired special effect.

11. The computer-readable media of claim 9, wherein applying a special effect to the selected video clip includes applying one or more of the following a threshold effect, a fade out effect, a speed up effect, a grayscale effect, a film effect, a rotate effect, a water color effect, and a sepia tone effect.

12. A computerized method for editing a video data stream being captured from a video source, said video data stream including a sequenced plurality of video frames, said computerized method comprising:

capturing the video data stream from a video source;

determining a property value of each of the video frames in the video data stream;

determining differences of the property values between successive video frames in the video data stream;

segmenting the video data stream into a series of video clips as a function of determined differences of the property values between successive video frames;

editing each of the video clips in the series of video clips as a function of the determined differences of the property values between successive video frames while the video data stream is being captured from the video source; and

displaying each of the series of video clips while the video data stream is being captured from the video source in a capture window.

13. The computerized method of claim 12, wherein determining a property value includes determining a content property value for each of the video frames by analyzing image content of each video frame in the video data stream using a color histogram, and wherein the segmenting includes comparing the distance or difference between the color histograms of adjacent video frames to a threshold value and defining a segment boundary between adjacent video frames having a difference greater than the threshold value, wherein said segment boundary segments one video clip from a next video clip.

14. The computerized method of claim 12, wherein determining a property value includes determining a time property value for each of the video frames in the video data stream being captured by analyzing time stamp data included in each video frame, and wherein the segmenting includes comparing the difference between time data included in successive video frames to a threshold value and defining a segment boundary between successive video frames having a difference greater than the threshold, wherein said segment boundary segments one video clip from a next video clip.

15. The computerized method of claim 12, wherein editing each of the video clips includes one or more of the following:
