Found recently in my in.mail an ad with such a text-effect:
Nothing fancy: when you add it to your projects timeline, It has a solid white background; in its Inspector, you can un-check the BG-box; but the light-weighted outline demands for a solid background.
The two top sliders set the amount of 'nervousness' and the amount of distance to the regular title.
The published crop parameters (t/b, l/r) allow to create a (opaque) bar or box as BG. As mentioned: nothing special, but an eye-catcher.
Feel free to modify to your needs, share customized versions here.
