Please tear off the matte film by hand when receiving the animation gyro, 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 come into contact with is 30 frames or 60 frames per second, that is to say, 30 or 60 different coherent pictures are switched in 1 second. Then the principle that our gyro can form animation is also in accordance with this law.

Question 2: Why can't the gyro animation be seen by the naked eye: Because the refresh frame rate of our naked eye is very high, then when the gyro rotates again, we can't see the fixed frame when we have seen the rotation.

Question 3: Why sometimes there is animation when shooting, sometimes there is no animation: Because when you choose 30 frames per second, then the gyro must meet the multiple of 30 turns/6(6 pictures) per second to freeze the frame to the picture, and then generate animation.

Question 4: Why do you have to shoot animation in the sun? The last question is that the animation is formed only when the freeze-frame picture is fixed, so we need to say from a single picture that a picture consists of Aperture, photosensitive, shutter. When we shoot a moving vehicle at night, there will always be a drag effect, because the light is too dark and the shutter is not fast enough. Then come back and say that under the high-speed rotation of the gyro, we must have enough light to take the fixed frame, so that the shutter of the mobile phone can automatically meet the high shutter, so that every frame of the fixed frame is rotated.
