According to typical practice of the present invention, temporal identifiers are simultaneously associated with (i) video and (ii) numerical data while these data are contemporaneously collected by, respectively, (i) a video camera filming an event and (ii) a data acquisition system acquiring numerical data from sensor(s) obtaining sensory information relating to the event. Various modes of inventive practice provide for time codes and/or markers as the temporal identifiers. The video and the numerical data are each converted to a digital form that furthers their mutual compatibility, the video to a compressed/encoded video file, the numerical data to an Adobe XMP data file. The compressed/encoded video file and the XMP data file are merged whereby the temporal identifiers are aligned with each other. The merged video file has numerical data embedded therein and is displayable so that the video and the numerical data are synchronized in comportment with actual real-time occurrence.
