Description

Please read carefully the product instructions How to use: When receiving the animation gyro, please tear off the film of the matte surface by hand, then you can use your phone's video (Recommended 30 FPS) function to animate it in the sun. 1. How the animation is 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 toy can form animation is also in accordance with this law. 2. Why can't see the toy animation with the naked eye: Because the refresh frame rate of our naked eye is very high, when the toy rotates again, we have already seen the rotation, and we can't see the freeze frame. 3. Why sometimes there is animation and sometimes there is no animation when shooting: because when you choose 30 frames per second for the video format, then the top needs to meet the multiple of 30 revolutions per second/6 (6 frames) to freeze the frame. , And then generate animation. 4. Why do you have to shoot animations in the sun: The last question talked about stop-motion images before they form animations, 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.
