Hey everyone, in this video we are going to talk about, why everybody is running in slow motion, with our footage, and there's a bit of a slurriness to everybody's voice. Then we're going to kind of move towards this, where we take our footage, and we speed it up, to regular size. "I don't like the day there's no limits." Slo-mo, awesome; ready? "… inside your head." So High Frame Rate, I'm going to do my best, to try and explain it. 

We're going to kind of touch back on Frame Rates in general, and I'm going to probably leave you a little bit more confused than when you started. It's not my goal, you let me know at the end how well we went. That's a nervous laughter. Not laughter of joy, like confidence. We can do this, let's learn High Frame Rate. 

We need to discuss High Frame Rate because the footage has been given to us in a kind of a strange format. So we need to understand it, so that when you get it in the future, or you're recording High Frame Rates, you are comfortable-ish with it. So I'm going to open up one of them, you'll notice that these are shot in High Frame Rates. They're all given to us in slo-mo, which is cool but weird. So let's-- we're going to end up doing this. The reason we want to do this is-- this is the kind of thing we're going to do. So have a look at this side. 

"We can jump so far and do all these awesome tricks." "I realize that there's no limits, all limits are inside your head." We want that slo-mo kind of effect. So we have a High Frame Rate, because we get to do really beautiful kind of cinematography like that. Now ours is okay, but you can go and look at things like-- like this has been shot at 60 frames/second. Everything else so far has been either 29, or 23, or 25, but this has been shot at 60 frames/second. A higher Frame Rate than normal. 

You can-- like it goes-- I think-- I just Googled the-- the fastest Frame Rate at the moment, and it's 10 Trillion. You can actually start to see light traveling. "So what we're seeing here is," Bananas; like light passing through something. And, if you-- like-- I need to acknowledge that this video took me about half an hour to make; why? Because I ended up going down a worm-hole with the slo-mo guys. These guys are amazing, they just shoot stuff in slow motion. It's worth having a look, just because. 

"Oh, you're ready for high adrenalin?" "You're like doing it for months." And underwater bullets, all that kind of stuff, is all shot in really High Frame Rate. These guys shoot in, I think, they've got like half a million frames/sec, which is obviously spectacular. Your digital camera is probably going to shoot standard, probably 60 frames/second. Most cameras do that now. It will get higher as we go along, but they've just got so much cool stuff. 

The one thing I would recommend going watching is, the slo-mo guys on YouTube, but the one that says how a TV works. It's kind of an eye-opening one for how video gets produced, especially if you're going out to broadcast. Not even that now, just any sort of understanding of television. They cover all sorts of cool stuff in terms of-- how the image-- "…takes an extremely fast…" how it's produced. And they go through kind of range of TVs. Anyway, you can do some beautiful stuff with it. Let's get back to our understanding. 

So let's understand High Frame Rates. I've got something in your Footage, called 'Frame Rate 30 FPS'. You don't actually have to open this, it's just an example that I'm going to use. It's shot at 30 frames/second, which is helpful for my math in this example, but it doesn't really matter if it's 29.97 or 25. The principles are the same. If you're like, "Why is it 29.97?," I don't really know. I know it's a technical bye-product of the olden days of television. And I researched it once, and it blew my mind. So just know that it's a very common Frame Rate in America, because of technical limitations that don't exist now. 

So 25 frames/second is very common in Europe and Asia, and 29.97 or 30 frames, it doesn't really matter, there's such a slight difference. So what I'm going to do is make a sequence from this, and down here I'll find a bit of footage that is nice. A little side note is, see how I'm dragging this edge, and two little windows appear. There you go. So there's just one, and if I drag the end of it, so you see, it compares to where my Playhead is versus where we're going to. So it's just kind of like a, give you a comparison of like what's left behind, which is empty space, to where we are now. 

So let's put in our one second, so it's one zero zero, '100'. I'm going to zoom in a bit. I'm going to hit my 'Marker' key. I didn't have the track selected so it went up there. Let's go in one more zoom. Now this is exactly 30 frames. So 1, 2, 3, and you count them all up to here and that will be 30, and because they're all stills, our little human brains can't tell the difference between live action. So this is my little example here of that exact same setup. So 0 seconds, one second, 2 seconds. It was at 30 frames/second. Well that's what it is now, and say we want to make it slow motion. So in Premiere Pro we can-- let me zoom out a little bit. 

So it's about 10 seconds long. I need to stretch it out, I can right click it go to 'Speed', somewhere, 'Speed Duration', and say, actually I want it to be half the speed, so it goes nice and slow, and it kind of jumps out because it's longer now, because it's half the speed. Let's have a look at our man, you can see, it is not very good slo-mo, because we just stretched it out, this is my little example here. So this is my 30 frames, these little cubes. If I stretch it out to be 2 seconds, you can see, there's still the same amount of frames, we just kind of stretch them out, that's why they're nice and jumpy now 

So I'm going to undo that because that's not what we wanted. There is better ways of faking that, but that's a really good example here in Premiere Pro, really jumpy. That's why this other stuff is shot in 60 frames/second, and is, oh, opened the wrong one, let's open this one. That's why this is all very slow. So that we have all those extra frames, so we can stretch it out. Now when you do shoot in 60 frames/second, so you get your camera, and you have a look through your settings, your cell phone will do it, it will shoot in a High Frame Rate. It's getting higher and higher, it's going to like 60, 120. Just some real simple cameras. 

So you've gone to your camera, you've set it up to shoot High Frame Rates, like our Videographer has, and you've found 60 frames/second, and that's probably the max of that camera, and you're like, "Great, I'm going to shoot it like that," so that we can go do cool slo-mo stuff. Now your camera is going to give it back to you in one of two ways. Let's have a look at both ways; I'm going to delete that. I've got, in your Exercise Files, there's one, there's two Walk 8s. There's a Walk 8, and there's a Walk 8 60 frames/second. So I'm going to add both of these to my Timeline. 

I'm going to keep my existing settings, so the first one is 60 frames. So this is-- my camera said, here you go, here's your video at 60 frames/second, and it plays at regular speed. Ignore that. Down here, the other version, that is 29.93 Random. This one here plays in this kind of really weird slow motion. They're the same thing, one is sped up, one slowed down. Let me show you in my example. I'm not sure if this is going to help. Sometimes it does, it feels like it's helping, and then sometimes it doesn't. 

So this was my old man walking, it's shot at 30 frames/second. This is High Frame Rate stuff, is 60 frames/second. So there's double the amount of frames, which gives us all that extra detail. So your camera can say, here you go, here's your 60 frames, and at 60 frames/second, so there's 60 little boxes, there's one second. It still plays over the right time, they just hold a lot of detail in there. So you can spread it out later on, and open it up and slow it down if you like, but it's still playing at the regular 60 frames in a second. 

That's this one here, playing at full speed. There's lots of detail in there, if I do want to slow it down, which is cool, and there's no real difference between which one you get, in terms of the end result of our slo-mo, but the other way you can get it, your camera can say, actually, I'm shooting 60 frames/second, I'm going to give you 30 frames/second, but I'm going to smear these out. So there's your 30 frames/second, but there's all this extra stuff, what do we do with it? Oh well, we'll just lump it in, and it will make it longer. 

So now that one second is now taking two seconds. That's why everything plays in this kind of like slo-mo version. That's pretty jumpy at the moment. So it doesn't really matter how I get it, you'll get both of them, some of them will say, here you go, 60 frames/second, and some of them will just be 30 frames/second, it'd be super slow, and this one here, we need to speed up to look regular, and this one here we need to slow down to get our amazing footage out of it. Does that help at all? I spent ages trying to work on that, it is confusing, even more confusing to explain. So if you found it useful, carry on, if you didn't, maybe drop a comment in there to maybe help other students explain it. 

Last little thing we might do is, this one here is playing at regular speed. If we want to get out, extract our amazing slow motion, you can change the speed. So I want it to be slower. I want to slow it down because I want to see all those extra frames, and I can never remember, is it 50%? Yep. So it's longer, so it's going to play in slow motion like the first one. This one's in slow motion, and we say we want to speed it up, which we're going to have to do for this video. So it's playing too slow, my computer is struggling to play it at all. It's playing a slow-mo, to speed it up, I'm going to go, you, I want you to be faster. How much faster? Double the fastness. There you go; let's have a look. Can't do it, poor computer. Let's go. It's playing at regular speed, badly. It's a bit stressful for this computer to do the Time Remapping, which we kind of just did, changing the speed, and also do the screen recording, and all sorts of other stuff. 

All right, let's go into the next video, and we'll actually go and change the footage, now that we understand it. We'll actually get it back to regular speed, and then just slow it down occasionally. High Frame Rates; more confused than when you started this video, or less confused? Next video.
