3.1 How to Use Fractal Noise
Hi everyone, and welcome back to Create Modern Glitch Animations in After Effects. In this lesson, we'll be going through how we can use fractal noise to animate or text here. So let's start of by removing these guidelines. So click on choose grid and guide options and then click on Title/Action Safe again, and this will remove the guidelines so that we've just got our glitch effect text here. And now, to start our animation, we'll need to create a displacement map. To do this just go to Layer > New, and let's create a new Solid, and let's go ahead and name this new solid DisplacementMap. So let's go ahead and type in Displacement Map, like so. Click OK, and this will create a new solid on top of our title composition, here, like so. So now, what we're wanting to do here, is we wanted to create displacement, fractal noise. So let's go ahead and click on Effects. Let's go to Noise and Grain, and let's select a Fractal noise. Now, you'll see here that because I had the title composition selected. It's actually placed the fractal noise inside the title comp, which is not what we want. So let's go ahead and select Fractal Noise, and delete that from our title composition. Make sure that displacement map has been selected, and now, we can go to Effect > Noise & Grain > Fractal Noise, like so. And you can see here straight away that its created this sort of cloudy effect within our new displacement map solid. Cool, so now, we can see that by placing the displacement map the effects inside the displacement map, we've also got the effects control up here next to our project panel. And we can just start to adjust some of these things, here. So let's go ahead and change the noise type from soft linear to block. You can see this changed the sort of cloudy look to a more pixely, blocky look here, like so. And we want to enhance this pixely look, or actually simplify this pixely look, so let's go from 6 to about 3. You can see that it reduces the noise of the pixels, here. So if we increase the value, you can see that it's more noisy, but we want to keep it simple, so let's keep that 3 for now. And now, next, we want to go to Transform, here. Open it up, and we want to untick Uniform Scaling, which will allow us to change the width and the height of our pixels. So untick that, and let's increase the width. Let's say we want to increase the width to about 450, and let's keep the height at 100, for now. Excellent, now, we have our displacement map setup. The next thing that we'll want to do is switch off the displacement map layer by clicking on this eye icon on the left, here, and this will keep the displacement map layer in the composition, but it will just make it so that it's see through, and we can see our glitch effect text again. Cool, so now, the next things that we want to do from here is make sure that our Title 01 layer is selected, and we want to go to the top menu, here, and select Effect > Distort > Displacement map. So now that we've placed a displacement map effect inside our title composition, and you can see that we've got the controls here, like so, cool. So now that we've got the displacement map inside our title composition, next thing that we want to do here is change the displacement map layer from title one to displacement map. And now, set the vertical displacement to 0, like so, cool. Now, at this point, we can actually start using the displacement map to animate the text. So let's go ahead and select Displacement Map, and make a pre-comp of this. So go to Layer > Pre-compose, and let's change this to displacement map comp, Like so. Move all attributes to this composition, click OK, and now, you can see that we've got two compositions within our glitch effects composition. Cool, so let's go ahead now and take a look at the animation. So if we select our Title 01 composition and go to Effects and Controls, and just bring our attention to the displacement map, here. We can actually start to, if we go ahead and change the vertical displacement, we can actually see how this affects our text, like so. Cool, so now, we can see that we've got a pretty simple looking text animation that we can use. So that's it for this lesson. In the next lesson, we'll be going through how to create a basic glitch animation using this new setup that we've created. See you all there.
