This is Kris Truini for Kriscoart Productions, and welcome to this tutorial which will cover the basics of After Effects. I know it's not the most exciting tutorial that you've ever seen, but in order to get to the fun stuff, we need to get the basics out of the way. Now, I know that this interface looks pretty intimidating, but once you get the basic mechanism of it and you know where everything is, everything else builds upon that basic knowledge. In other words, this tutorial will try to include all the basic needs to get you started into one video. All right, enough talking about the tutorial. Let's actually jump into it. So the first thing that we see in this interface is that it's divided into panels. You have your Project panel over here, which also shares the Effects Controls panel. The Project panel is where all your media, which can be footage, audio, images, anything like that will be stored here. Anything that you use will be imported in the Project panel. Right next to it, there's a Composition panel. This is pretty much your monitor. This is where everything that you do in your timeline will appear. Before we start exploring the rest of these panels, let's actually import some footage so that we can get a better understanding of what everything does with an actual example. So to import your footage, you can either double click into this Project panel area, and this will open up this Import File window, or you can import files through File, Import, File, or Multiple Files. So you see they'll pretty much give you the same thing. Or, if you have a folder open already with the footage that you need, you can simply just drag it over onto this box or into the Project panel area. Okay, so we now have some footage imported, and you can see that there is some basic information here. It gives you the resolution, the frame rate, the amount of colors, and the type of compression that this video has. So, moving on from here, what you wanna do is create a new composition. There are a couple of ways of doing this. You can either drag the footage onto this little icon here, which will create a composition based on the settings of the footage. So it'll have the same frame rate, the same resolution. Now, another way to do this is to go under Composition, New Composition. You can notice that the shortcut for that is Command + N. For PC users, I'm pretty sure it's Control + N. Okay, so now that we have a composition created, let's look at other ways to import files onto your timeline. So what I have here is a simple picture that I'm gonna import. So what I'm gonna do is I'm gonna create for this example a small logo overlay in the lower third of this video. So there are two different ways to bring this image into our timeline and see it in our Composition panel. One way is to actually select it and drag it over the composition panel. And you can see that this little box appears, and what that is is pretty much the size of the image. So we can see that up here it's 900 by 900, and that's actually what's showing into our Composition panel. And you can pretty much drag it anywhere you would like, and as soon as you let go, it'll place it in that position. Now, the other way is a little bit different, because instead of working on where you wanna place it, it works on when you wanna place it. So you can see that this black line forms soon as we drag it over to the Timeline panel, and that is because you're telling it first if it should be on top of the clip or under the clip. If you place it under the clip, you're not gonna see it because our footage is actually covering it up. But if we bring it up by selecting it, bringing it on top of the clip, you can actually see that it appears over our footage. Now, another important thing of this technique is that, let's say I'm dragging it over, you not only get to choose in what order it is placed, but you also get to choose when in time it is placed. So once again, if you drag it over the Composition panel, you're choosing where your item is placed, but if you drag it over the Timeline panel, you choose when it is placed. Now, if you notice, whenever you drag an element onto the Timeline panel, this secondary timeline indicator knob appears, and that's pretty much telling you where the beginning of that layer will be placed in time. Okay, so again, it's very basic stuff, but we're actually getting somewhere. We're starting to get more comfortable with After Effects. However, if you have a short attention span like me, I think it's probably time for a break. So here's some slow motion stock footage for your enjoyment mixed in with some dubstep. Enjoy. (dubstep music) All right. I feel much better. So, let's get back to work. So once again, what we were trying to do in this example is to create a lower thirds looking logo overlay. Instead of having the logo appear over here, I'm just gonna drag it back to the beginning so that we immediately see it. And the next thing we gotta do is pretty much scale it down and position it down in the bottom. So there's a couple ways to do this, like most things in After Effects. One is to shrink it or resize it or stretch it with these little points on the edges of the picture. Or you can click one of those points and hold Shift, and that will uniformly scale the element. Another way to scale layers is to select them and hit S on your keyboard. That will bring up the scale property of that layer. So over here, you can see that we can click and just drag it in and out. Or, if you want, you can select it and type in the value that you would like. All right, so let's scale it down to what we want, so I'd say that's pretty good. And we wanna position it down here. So all you gotta do is just click the layer and drag it over. Now let's say you have many layers and elements in your composition and you can't really click them. Well, just how we brought up the scale over here, you can select it and hit P, and that will bring up the position of the layer. And then you have the X and Y coordinates and you can drag and position the layer where you want it to be. Now, while we're here, let me just mention a few other things. You now know that with hitting S, you bring up scale, hitting P, you bring up position. Well, here's a couple other ones. If you hit R, it brings up rotation, and you can actually rotate your layers. If you hit T, it'll bring up the opacity. And opacity is pretty much how transparent your layer is. So if you bring that down, you can see that we start seeing more of what's behind it. Another cool keyboard shortcut is instead of seeing them individually, if you hold Shift, you can actually bring more than one up. Okay, so before we move on to animating some of these properties, let's actually see a couple other keyboard shortcuts that can help you import things quicker and work with your timeline a little bit faster. So let's say you wanna import something down in the middle of your composition.
