Transition Node

I'm working on a vertical swipe across the screen where one image would come in as the other one swipes out. I need the transition to happen from frame 1 to 13 and have been unsuccessful thus far of doing it with this node. It transitions until frame 4 but on frame 5 it just cuts to the second image.

The only overlap that works is : 50 otherwise there's no transistion.

I've never used this node before, any s uggestions?

dunno about the transition node (never used it), but i'd probably just use a keymix with a moving vertical alpha as key input.

hope that helps a bit

Just animate a rotoshape, takes 5 sec to do.

Color1 = Color(720, 486, 1, 0, red, red, 1, 0);
ColorWheel1 = ColorWheel(720, 486, 1, 0, 1, 1, 1);
Grad1 = Grad(720, 486, 1, 0.5, 0.5, 1, 0, 0, 1, 0, 0, 1, 0, 1,
0, 0, 0, 1, 1, 0, 0, 0, 0, 1, 0);
Pan1 = Pan(Color1, Hermite(0,[0,98.94,98.94]@1,[720,98.94,98.94]@13),
0, 0, 0.5, 0);
KeyMix1 = KeyMix(Grad1, ColorWheel1, Pan1, 1, "A", 100, 0);
