A master-slave video playback interface in which a master video player is time based, and a slave video player displays a second video georeferenced to the first, e.g., the georeferenced frames of the second video in closest proximity to those being shown on the master player. The invention allows more efficient simultaneous viewing of multiple geo-tagged videos acquired at a singular geographical location, to compare videos, for example, collected on an oil or gas pipeline Right Of Way (ROW) at different times to monitor encroaching threats to pipeline integrity.
