I have used MorphX from Norrkross software successfully several times, it is free software, it does take a bit of tweaking to get the settings right, and the more time you spend setting morph points, the better the morph will turn out. I have used it to morph between 14 photos (following a subject from age 4 to age 18) You simply create each morph and then string the quicktimes together.
