I thought I might be able to do this with a mask somehow, but I can't seem to figure out how. The only hack I could find was to produce your text first in a video, and then add that video to another video, which is pretty bogus and won't work for me.

- Image #1
- Image #2 overlay at the top (a fancy title image)
- Credits Scroll Text - I need this to scroll on screen and disappear before going under the title Image #2
