Please read carefully the product instructions:

After receiving the animated spinning top, please tear off the matte film by hand, and then use the mobile phone video function to shoot the animation in the sun.

Question 1:

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.

Question 2:

Why cant we see the top animation with the naked eye: Because the refresh frame rate of our naked eyes is very high, when the top rotates again, we have already seen the spinning, and we cant see the freeze frame.

Question 3:

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 a multiple of 30 revolutions per second/6 6 frames to freeze the frame To the screen, the animation is then generated.

Question 4:

Why do you have to make an animation in the sun? The last question talked about the freeze-frame image before forming an animation, so we have to look at a single picture, a picture is composed of aperture, light sensitivity, and shutter. At night, when we take a picture of a moving vehicle, there will always be a smear effect, because the light is too dark and the shutter is not fast enough. Then come back and say that when the top is spinning at a high speed, we must have enough light to take a freeze-frame picture, so that the phone shutter can automatically meet the high shutter and freeze every frame in the rotation.
