Several things you could do.
Put the tittle on a background that is a color far away from it. Produce that and re import it. Chroma key the background Then you can use it as a PIP video.
You could also type the tittle in an external image editor then use it as a PIP object, just put it on a transparent background.
And finally you can adjust the duration of the entrance stay and exit of a tittle when an effect is applied to it.
PDTOOTS has alot of helpfull tutorials on things of this sort.
