,How does higher frames per second like 10000 fps mean a super slow motion video??
In: 102
Is this for real??? Are there actually devices capable of recording at 30,000 frames per second – or even 10,000 frames per second.? What are they called?
More frames in video is like more pixels in a photo. When you have more pixels in a photo you can zoom in further. When you have more frames per second in video, you can slow it down further.
It’s not that it’s super slowed down, it’s that there’s a lot more pictures being taken within that second that you can go through, 30 fps gives you 30 pictures to look through, and 10,000 fps gives you 10,000 to look through
The fps here is referring to how many frames the camera *captures* every second, not how many are played back. So you capture 10,000 frames in a second, then play them back at a normal 24fps (or 30, or 60, or whatever) and boom, extreme slowmo.
Because that’s the speed at which it was recorded; it’s played back at (roughly) 24 frames per second. So if you take 10,000 pictures (frames) in one second and then play them back at 24 frames per second it will take 10000/24 seconds (almost 7 minutes) to play out what took place in 1 second, dramatically slowing down the action in the video.
It doesn’t have to make the video super slow motion, but if you play back 10k fps in 1s, you won’t see much different than whatever our eyes can perceive (some say 30-60 fps, some think a bit more, but not much).
So we slow the video down to 30-60 fps, which makes the video appear super slo-mo
The human brain generally perceived at around 30 fps. If you go slower than that things look “off.” So when you record an event at 10,000 fps, and play it back at 30, that 0.1 second long event will look like it takes a minute to run. And because you’re running at a speed the brain likes, the motion looks natural.
Take a video captured on a 30fps camera and play it in slow motion. You get a slide show. Capture more frames per second and then when you play it in slow motion, there’s more pictures to make the motion seem more fluid. Instead of the objects in the video jumping around, you get to see more pictures in-between them “jumping around”, so the video looks more fluid.
To say it another way, you can play literally any video in slow motion. It’s not that a higher frame rate camera produces a slower video, it’s just that a higher frame rate camera captures more information so that when you do play it in slow motion it doesn’t look choppy.
Think of two ends of a staircase: beginning and end. You gotta stop and look at any painting placed at any step between them. Put one painting between them, you get really fast from one end to the other. Put twenty four paintings on the steps between them, you’ll take longer, but still relatively fast. Put a thousand paintings on the steps between them, now you really are gonna take a good long while looking at each of the paintings in turn before reaching the end. Sorta what happens when the camera’s reproducing a thousand photographs. It crunches them all into a second, but it still has to put them all on the screen in turn. This makes it look like time is running slow, because, well, it sorta is. You’re looking at many more photographs of the action than you would at twenty four.
So lets use your number “10,000”. In a second there’s 1000 milliseconds in a second.
that means you’re taking 10 images every millisecond.
Alternatively, 30 FPS means you’re taking an image once every 300milliseconds.
I’m sure my maths is wrong, but the point still stands.
