The very first thing we see is Bilbo putting stuff in a chest, and I thought it was played twice as fast. But then I realized it's just a thing you need to get accustomed to. When you go into a cinema, you expect a film to look a certain way. HFR doesn't look like that at all, which is why your brain needs to learn how it is supposed to work.
I felt the exact same way! Bilbo's hands seemed to be moving at super speed!
