Hi everyone, this video we're going to talk about Frame Rate, or Frames/second, or FPS. You can see it here, because in footage imported into Premiere Pro, this one says it's 25 FPS, Frames/second. It's referred to as the Frame Rate. The easiest way to understand Frame Rate is to look at our flick book. So this flick book here is obviously a lots of single drawings. Let's have a quick little look. 

This one here is a really cool tutorial, animation, how to make a flip book, but basically drawing every, like every frame, remember, our frame is just a singular point in time, a little snapshot, and he draws every single one of them, but if you run them together, let's have a little look. Where are they? Watch, if you run them all together, all those frames, it starts looking like real motion, let's go back to-- there you go. Cool, huh? 

So that's probably a Frame Rate of about 5, or 6, or 7. 7 Frames/second, us as clever humans, we can see every frame, we can see the jumpiness of it all. We can see that it's a non-- here we go, there's a bit jumpy, but if you go-- if you run that a bit faster, the humans aren't so smart, we can get to about 25 Frames/second, and we all feel like it's live action, like happening right in front of us. So let's have a look in Premiere Pro. 

So I know that if I pause it here, I'm not moving, and if I go one frame ahead, I'm going to click down here, and use my keyboard shortcut left and right, just go forward one, look at that. That's another one, another one, another one, another, another, another. So if I speed this up I'm smashing away at the old keyboard, eventually if I can hit that 25 times in a second it looks like this. So that's the Frame Rate, collection of stills, run fast enough, that us clever humans can't tell the difference between, a collection of images and actual live, right in front of us happening right now. 

So how do they go, it's a hard thing to understand. I guess, probably the-- let's talk about the different standards. The standard at the moment is probably 25 Frames/second. Anything digital is normally either given to us at 25, or expected to be 25. Now the cool thing about it though is, you can be at this level of Premiere Pro production, doesn't really matter what you get or what you export, things like social media and websites will accept any sort of frame rate. Where you have to be concerned is if you are shooting to, like production schedule or at least some specifications that says, "I want from you 4K at 24 Frames/second," then you have to be a bit more specific. 

Lots of cameras, you can go into the settings and pick the Frame Rate. All kind of digital video cameras, DSLRs, cell phone cameras, all have some sort of option often to increase it, increase the Frame Rate. We'll talk about that in a second. All right, we're in and gathered some stuff with strange Frame Rates. Now this one here is 30.06, this was, this, me walking with my headphones. So this, why is that one a weird Frame Rate? Cell phones often have what's called a variable Frame Rate. It changes over time to get, basically get the smallest file size it can. So you've got this weird size, this was shot for our 'Wedding', this one shot at a really strange Frame Rate. So what is it? 29.976, another really random one, but what ends up happening is all of this stuff. 

If you've got, you know, you can't reshoot this at a different Frame Rate. It would be lovely if we told everyone, shoot everything at 25 frames, because there is a tiny, if I drag this onto my 25 Frames/second Timeline, let's go to the 'Mountain HD', I add this one here, it's not quite the same, it's the same size but the Frame Rate is going to be adjusted to be this 25, and there's going to be, I don't know, you have to be a pretty purist, and it has to be some pretty amazing footage to start with, to notice the difference, but there is a difference. 

Thumping 23 on a 25 will convert that 23 into a 25, but I just want to, I guess, I don't want to get you scared, at this level, before you get into more advanced stuff, it doesn't really matter. You can export it, drag all this onto the same Timeline, and when it exports it will export as 25 Frames/second, because that's what we told this HD sequence here to be 25 Frames/second. Where things get a little bit more useful for you, when you are getting started at this level, is something that's like 60 Frames/second, or 50 Frames/second. You can shoot really high Frame Rates, and you can do some really cool Slow-Mo, but we'll do that later in the course. 

This is just like an introduction to Frames/second, because we're in this kind of like, technical understanding section of the course. That's why when you make a new sequence, there's all these options in here to say-- let's have a look at, let's look at NTC, let's look at Standard one, this one is 29.97, this is what TV in America used to look like. Doesn't work the same way anymore, because it's digital and satellite, and this is what it did in my part of the world, we used PAL, which was 25 Frames/second. Cinema, if you go to the movies, they use 24, you're like, "Why are we still using 24 there?" I don't know. 

There's all these rules that are kind of often legacy rules, somebody picked 24 for cinema, somebody else has picked 25 on a digital camera, and we've all got this kind of mixed up Frame Rate now. There's a little bit more consistency now, 25 becoming more or less the standard, but 29.97, and 24 is around, but again, using 25 is a good all around standard, unless you've been asked specifically otherwise. 

I hope that helped understand what Frames/second is, and we'll use it to our advantage later on when we do Slow-Mo. All right, that's it, let's get into the next video.
