Hey there, this video is all about mixing 4K video with HD video. We'll discuss how to scale the small stuff up, and the big stuff down. Before we get started let's close this project, it's getting a little confusing, trying to throw everything into that same project. We're going to make our own new project. So go to 'File', 'New', we'll go to this 'New Project' button, and we're going to call this one 'Tech Info', I'm going to call it 'v1', because I can't think of a better name. 

I'm going to stick mine on my desktop, it's just like a throwaway project, just to kind of show us, you know, to practice a few things. Click 'Choose', click 'OK'. Let's import a couple of files, so just double clicked in the 'Project Window'. We're going to bring in 'Clouds HD' and 'UHD', click 'Import'. Next up, let's create a sequence. We're just going to create a little turned up page here. I'm going to create a kind of a sequence on our own. So we're going to use just a really common HD size, is under 'Digital SLR', and we'll use this one here, the 1080, which is the height, and 25 frames/second. We'll talk about frames/second in a sec. We'll call this one, let's call this one 'Mountains'. This one's going to be the HD version. 

So what happens when I've got this HD size, it's 1080 high, but I want to put in the UHD, or the 4K footage. I drag it onto the Timeline, you get this warning, 'The clip does not match the sequence settings." What do you want to do? You get to decide, "I want to just keep the settings as I've got it," keep it HD, because that's what I want it to be, or you can say, "Actually, yeah I didn't realize they didn't match, I want you to upgrade, and change my sequence, to match this new bit of footage going on to it. It will transform it from being HD to UHD, to match the footage. So you get to decide what you want to do here. 

If you don't get this warning dialog box, it's kind of hard to get it to come up sometimes, find it a little bit-- sometimes it appears and sometimes it doesn't. Let's say, 'Keep Existing Settings', and if you can't find that little warning dialog box, and you want it, it's under 'Premiere Pro', 'Preferences', and in your-- on a PC it's slightly different, it's under 'Edit', and down the bottom here, 'Preferences', then go to this one called 'Timeline'. It used to be in General, just check if they've moved it back, but at the moment it's under 'Timeline', and it's this one here, it says, 'Show Clip Mismatch Warning dialog'. You can turn that back on. So it came in and you're like, "Okay,' great, it skipped HD, and it's put my really big footage on here, and it plays back okay.

I've lowered my quality a little bit, but it's just really massive. So let's go to a view of like 25, if I click on my footage, you'll see that-- actually just double click it in the screen, you can see it's actually a lot bigger than that size. So you want to shrink it down, you got two ways of doing it. Let's zoom in on our footage here. The two ways are in the same place, you right click your footage and you have Scaled Frame Size and Set to Frame Size, they do a very similar job, but basically--

I'll explain the difference, but you want to do Set to Frame Size all the time, pretty much.Think you're all Set, we're set, This is best as I could do, but Set is good, Scale is bad. Basically if I do Scale, or I do Set, they look like they're doing the same job. Scaling down actually lowers the quality of the footage. So if you ever have to like lift it up again later on, it will actually be quite pixelized. So this is kind of like scaling it down, but also pulling the resolution out of it. If we look at the Effects Controls, under 'Motion', you can see the Scale-- So I'll undo it, so I right click, and if I do 'Scale, Scale is bad because, it's left the scale at 100, and just kind of like ripped out a lot of the quality. 

So now if I try and scale that up to like 110-- 200%, it's actually pixelizing it, and kind of like making it not as good as it was. So if I do the same one, but I use-- we're all Set with Frame Size, here we go, it's scaled at 50%, and I can come back up, and it's still got all that good quality in there. So you're all set with Set to kind of resize it down. Let's go back up to 50, there we go. It works the same way the other way around. 

So let's go to our Project Window and let's do a 4K version. To make a 4K version, if you want to make one by itself, without using the footage to get started, you can go into 'New 'Sequence', and there's not a lot-- I feel like Adobe, probably, in the future, are going to have a nice HD or 4K kind of drop-down. At the moment, probably the easiest one is under your red camera. They've got a 4K little sequence here, a bunch of different kinds of 4K, but let's click on this one here, 25 frames/sec. You can see, this is the wrong one. 

So it's the-- it's too too wide for us, we want fake 4K, which is HD 4K. Even a different word for it, it's the same thing. Let's have a look at this one. You can see here, it's the proper width, 3840. So let's click 'OK' in that one. You can give it a name here before we go out. So this one's going to be 'Mountains', this one is going to be '4K'. If we add our HD footage - we're going to drag it and add it, - it's going to say, "What would you like to do?" I'm going to say, "I want it to keep 4K, please, just keep the existing settings", and what I'd like to do is, the same thing, right click it, and blow it up. 

Remember, you're all Set with Frame Size, and that's going to be the best way of doing it. It doesn't really matter as much when you're scaling it up. Know that it's going to kind of be 4K. We've scaled it up, but obviously the quality is not there. It's going to try and stretch it bigger, so if you're combining two, so let's say we've got this actual 4K footage, that fits in there nicely, playback is a little slow because it's so big. So I'm going to lower my quality down, but this one here, is actual 4K, and this one here is just blown up to 4K. So you, yeah, you match the two, you got to decide whether you want to bring the lower quality stuff up, to match 4K, or do you want to lower the 4K stuff down, to be the exact same as the HD stuff 

All right, that's enough of that 'nerd'ery. 4K, UHD, HD, matching it, it's going to be it for the moment. Let's get on to the next video.
