Hi,

Titler Pro 3 is a NewBlueFX product, not a magix product.  I do not actually use it, but if you can export the title as .MP4, or any other standard video format, there is no reason why you could not be able to drag the title into the timeline in PhotoStory.  This question might better be asked of the people at NewBlueFX.  My experience with NewBlueFX is that they are very responsive, so use their "contact" form and ask this question of them.
