11. A method of determining how likely a query video clip matches an original video clip, the method comprising: generating a signature distance measure as a sum of differences in dimensions between an individual query signature generated from a frame of the query video clip and a selected original signature generated from a frame of the original video clip that when compared to a threshold indicates the frame of the query video clip and the frame of the original video clip are likely similar frames, wherein the original video clip is an entry in a video database and wherein a signature is comprised of multiple dimensions of an image in a frame of a video; generating a time correlation to compare the likely similar frames of the query video clip and the original video clip by selecting different close-by frames of the original video clip and the query video clip to determine whether a close-by frame provides an improved distance measure indicating an better pair of matching frames; and generating additional distance measurements and time correlations between a sequence of different frames of the query video clip and the original video clip to determine how likely the query video clip matches the original video clip.

The method of claim 11 , wherein the time correlation uses a relative time rate between the original video clip and the query video clip as determined by a first few matching signatures between the original video clip and the query video clip.
