  • RandomPyraminx reply the reason the fidget spinner looks off when it spins on camera is due to the speed it is spinning at, and the way the camera is recording. the camera doesn't record one video, but a ton of pictures at a rate so fast that it creates the illusion of motion. the amount of time in between each picture is usually short enough for it to not matter much. however, when you have an object moving as fast as the fidget spinner, it can't capture the motion it produces fast enough to copy how it looks in the real world. it looks like it's spinning in the opposite direction because the spinner makes slightly more than one revolution per picture, or "frame". due to this, it ends up capturing the result of the position change, instead of the motion that it got there with, and the fact that it's moving slightly farther than one rotation makes it appear as if it's spinning backwards, when it's actually spinning forwards so fast that by the time the camera captures a frame, it's already changed posi...moretion in a way that makes it appear as if it's going backwards. it eventually appears stationary due to the fact that the speed it spins at slows to almost exactly one full revolution per frame. because of this, the position change was almost exactly one full spin when the next frame is taken, making it look like it's still. think of it like a swinging pendulum, or a swinging chain watch. if you took a picture of the pendulum everytime it was at it's lowest point, took all the pictures, put them in a slideshow and sped it up really fast, it'd look like it was in the same position, while creating slight distortion due to the position change that's actually happening. this is a similar concept. it starts to spin in its actual direction shortly after, because the speed the fidget spinner is spinning at slows down a decent amount, so that it revolves less than once per frame (something like 0.9 revolutions, then 0.8, etc.), and it keeps slowing down until it gets to the point where it's slow enough for the camera to capture how it actually looks irl. why it distorts is hard to say though. i do believe it's because, while it appears stationary, it's actually moving at a really fast rate, so the change of position results in distortion. assuming it's filming in 30 fps (just as an example), that is actually 30 position changes that are close enough together to create the appearance of it not spinning. there's bound to be distortion if the position change isn't VERY precise. (i'm not certain of this though, that's just the best guess i have) also, nice to see you on vidme. glad to see there are good asmrists who post here
