You have to keyframe the position of your text.
For the text to appear as single letters, use the starting effect "Popup I". It is the effect, that has the nearest look as if the letters were typed. I did not find anything better.
I did not find an effect, that make a text appear from the center. If you have one, use that effect (and be sure to share it on the cyberlink website
)
I made a little video to give you an idea, what I mean.
Please excuse my english, it's not my native language.
