Multiple Speakers and Collabs

Time them chronologically The gap between the two speakers shouldn’t be too far away from each other in terms of how many lines they are separated in aegisub. As much as possible, make sure that both lines appear and disappear at the same time . If one of the speakers ends at least 500ms earlier (including lead out), then you may cut the line’s timing there. No matter what, the lead-ins of both speakers should relatively stay the same and appear together.
