I've got a wiggly route that is Eastwards, mostly horizontal, but then springs up and takes a Northern route.
Tried so far:
1 - Mask: Moving Mask - ugh . . . tortuous . .
2 - Transition: Transition using Linear Wipe is good for the East Route but then the swing into Northern, it gets really silly!
I vaguely remember Douglas Spotted Eagle having a clever Composite method, but for the life of me, I can't find it, here or the COW.
I've briefly noted this one: https://www.vegascreativesoftware.info/us/forum/route-animation-plugin-for-vegas-pro-by-peter-p-with-tutorial--116423/ I need something more straightforward.
So, all suggestions are taken seriously.
