preview playback speed

[Lab lady]

I have built a morph on mac using four photos. Preview playback accelerates at the end.How do I set it to be the same as the beginning? 'Don't remember ever having this issue with windows... bought it in 2013. Just bought mac version last month. Would really appreciate a phone contact number.

Each morph in the series has it's own length and you can set the length (in frames, or seconds) in the Morph Options for that morph. If you have 4 pictures, you probably have 3 linked morphs. Look at the length of the 3rd morph in the Morph Options for that morph.
