1. A system, comprising: an analysis computer, in communication with first and second capture devices, programmed to: successively compare a selected data frame from a second set of data frames associated with a second capture device with each data frame from a first set of data frames associated with a first capture device; identify a first pair of duplicate data frames in the first set of data frames and the second set of data frames, and calculate a time stamp difference between the first pair of duplicate data frames; and, remove one duplicate data frame of the first pair of duplicate data frames from the second set of data frames and adjust a timestamp of each data frame remaining in the second set of data frames by the timestamp difference.
