Abstract: A respective user modifies (e.g., selects, drags, and drops) either one or both of a first visual representation of a first video clip segment and second visual representation of a second video clip segment to overlap with each other in order to create a so-called transition region while in an editing phase. In response to creating the overlap, a respective video editor application herein splices respective ends of the first visual representation and the second visual representation to indicate where respective first and second content overlap with each other. For example, to more clearly depict the spliced ends of content on a respective display screen, the video editor application initiates display of an overlapping content region to include a first region in which the first content appears to be overlaid on the second content and a second region in which the second content appears to be overlaid on the first content.
