Please read the product instructions carefully, the effect only can be seen by video, please use your smartphone video mode to see it. 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 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 the multiple of 30 rotations per second/6 (6 frames) to freeze the frame To the screen, then the animation is generated. Question 4: Why do you have to make an animation in the sun? The last question talked about the freeze-frame image to form an animation, then 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 top is rotating 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.
