I'm trying to make a rolling flash run across my text in Adobe PPRO 1.5's title maker. I've figured out allot of ways NOT to do it, any feedback on a successful setup to make this work?

I'll try to post a diagram:

Flash starts left...rolls 3 seconds...ends right

I-----------------------TITLE--------------------I


I want the flash to come from behind the letters. I know you've seen this effect before I just can't get 2+2 to equal 4. Even if it's creating it in a 3rd party program and importing it would be fine =)

Thanx in advance for the help.
