Frequently ask questions

Question 1:How is the animation formed: The video we generally encounter is 30 or 60 frames per second, that is to say, 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 can't 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 can't 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 we want to take a freeze frame when the spinning top rotates at a high speed. There must be enough light to let the phone shutter automatically meet the high shutter speed and freeze every frame in the rotation.
