The whole PV had around 4-5 cuts though. Normal PVs they only need 1-2 cuts. Making me wonder if a perfect run of this dance is even humanly possible.
It seems common that a group just learned the choreography shortly before shooting an MV. Sometimes, they even make changes practically on the set. In the case of C-ute's Aitai Aitai Aitai na, there was a decision made at the very last minute to switch Chisato and Airi for the intro.
In addition, the fact that only clips of dance shots are used in the final MV means that they aren't going to be picky about having everything in one clean take. It's not that they can't do a perfect take after sufficient practice, it's that they haven't had tons of practice and don't have to do it perfectly for the MV anyway. By the time they perform on stage, they've usually ironed out all the rough spots and usually perform even better than what you see in the MV.
I love how there's lots of wing-flapping moves that match the lyrics. I think this may be the most intricate dance I've seen them ever do!
