In FF X there are models used for cutscenes then there are models used for the map and battles. Sometimes 'cutscenes' that are short use the battle/map model. Notice the face.
Ah right, so I guess there are three models then on ffvii. Over world, battle, and fmv. I don't think they fully understood how it should all look when they made it.
Plus I think the battle and fmv model in ffx weren't so startlingly different. The fmv model evolved too. The aeris death scene looks great, but differs from the fmv models later on.
