Alex4D Transparent Blur implements an iOS 7-style overlay for type in Final Cut Pro X. Free download: http://alex4d.com/6-alex4d-transparen...
It slides an area from the bottom, top, left or right edge of the screen. The area is a blurred, reduced-contrast version of the clips it overlays.
You can choose to brighten or darken the background and control the amount of blurriness.
