How is the animation formed:
The video we usually encounter is 30 or 60 frames per second, that is, 30 or 60 different consecutive pictures are switched in 1 second. Then the principle that our top can form animation is also in accordance with this law.
Why sometimes there are animations when filming and sometimes there are no animations: because when you choose 30 frames per second for the video format, then the top needs to meet the multiple of 30 rotations per second/6 (6 frames) to freeze the frame To the screen, then the animation is generated.
