Taking advantage of the new transition editor in Pte AV Studio 12, which saved a lot of time when creating them, I made 20 transitions, each approximately 10 seconds long. In this case, the slide has a duration of 9.90 seconds, the same as the transition.
I'm including a link in case anyone wants to try them.
