Disclosed herein are systems and methods for causing a stunt switcher to run a multi-video-source digital-video effect (DVE). An example method involves (i) selecting a first log-entry from a traffic log, wherein the first log-entry corresponds to a first video-component (VC) and a first start-time; (ii) selecting a second log-entry from the traffic log, wherein the second log-entry corresponds to a multi-video-source DVE, and a second start-time; (iii) causing the first VC to start being channeled through the stunt switcher proximate the first start-time; (iv) making a determination that a threshold time-period remains before the second start-time; and (v) responsive to making the determination, (a) causing a second VC to start being sent to the stunt switcher, and (b) causing the stunt switcher to run the multi-video-source DVE, thereby causing the stunt switcher to output a combined video, wherein the combined video includes the first VC and the second VC.
