imovie intro problem

[qwerty546]

im tryng to make a title for a movie i am making with a zooming text over an aged film background. the problem is that it looks fine in the preview but when i apply the aged film it turns the screen white and i can no longer see the text or anything.

EDIT: never mind problem solved
