If that gif is morphed, it represents a staggering amount of skill and work. Is there any way to morph motion other than morphing each frame - and then coordinating each transition? Staggering.
That GIF has 64 frames, so you are right it would be staggering to work each frame. It is not something that I would have the patience for.
I didn't think that Carmella was that big, so I am thinking that it is a morph. I don't know for sure.
I think you are more of an expert on morphing than I am. So I would very much value your opinion on the matter.
EDIT: I take that back. I just looked for her videos and she is that big. WOW !
