Video transitions: unable to center at cut
Sometimes when I apply a cross-dissolve (or other) transition between two video clips, I can only apply it to either the end of the first clip, or to the start of the second clip; I can't drop it on the center of the cut. I usually want it centered on the cut, but in such a case when I go into the effects panel to change it to be centered on the cut, the "Alignment" option is greyed out, so that I can't change it to be centered. I haven't been able to figure out why that sometimes happens, and how to fix it. Suggestions? (CC 2017.)
