O.k., so it's late and I've gone brain dead!
I've got video footage that's completely black in the lower half of the screen, with people running around in the upper half.
What I'd like to do is have a text scroll that shows up against the black, then disappears as it reaches the people in the upper half.
There must be a simple way to do this -- maybe I can figure it out in the morning, but need to finish the edit tonight if possible.
Any help greatly appreciated.
Jack
