Sorry, but you posted in the wrong forum. This is the Adobe Captivate forum, not the Premiere Elements forum. I'll move your question.
What computer operating system? Have you updated 13 to 13.1 yet using an opened project's Help Menu/Updates?
To your immediate question....first thing I though...what is "photo morph"? My first impression is that it appears to be video animation of the evolution of a person's face with time. Unless you could be referring to a new Morph Cut Tool in Premiere Pro?
I suspect that with time and the combination of many techniques and effects one might be able to achieve the face evolution with time effect. But my first impression would be to use a software that is described for photo morph.
Please consider and supply more details.
