Hey dude,
black represents scene 1 and green represent scene 2? I do not think this is possible using native functions, maybe with some external plugin...
I think stinger transitions only work with a cut, so the transition video needs to occupy the entire screen at a given moment, if you figure out a way to do this, I'll want to know, that's exactly what I need and I did not find a practical way to do it.
Thank you and sorry for the wrong English.
