Woah! Was it meant to be this fast?

The animation is normal speed (you can just count the frames to see) only the camera is above 24fps because the first 154 episodes of Shippuuden are VFR.

VFR is more difficult to encode for and most ignore it so a solid 99% of the fanbase has never watched Naruto in the correct frame rate

See the camera PAN's in post #157964 for example. These just move horizontal/vertically so it's not as noticeable as the handheld camera in this post

I'm a year late, but thank you for the explanation!
