If the transition, when I create it, I cannot give it the time that I want, for example, 10 seconds of transition, when I apply it, if I remember the seconds that that transition has, I can give it the time that the video of the transition has, but if that transition is used by someone else, it will not know the real time that the transition has, it assumes that it is two seconds, so if it has to be playing with the times, it is a waste of time, apart from the fact that if it is not given the real time, it will not be seen good.
