Abstract

Disclosed herein are systems and methods for causing a stunt switcher to run a snipe-overlay video effect (DVE). An example method involves (i) selecting a first log-entry from a traffic log, the first log-entry corresponding to a snipe-overlay DVE, to a snipe video, and to a start time; (ii) selecting a second log-entry from the traffic log, the second log-entry corresponding to a video component (VC) and the start time; (iii) causing the VC to start being channeled through the stunt switcher proximate the start time; (iv) making a determination that a threshold time-period has passed since the start time; and (v) responsive to making the determination (a) causing the snipe video to be sent to the stunt switcher, and (b) causing the stunt switcher to run the snipe-overlay DVE, thereby overlaying the snipe video on the VC as the VC is being channeled through the stunt switcher.
