8.3 MORE EFFECTS!
In this lesson I'm gonna pick up right where I left off in the last lesson, and talk to you about some more very useful effects you're gonna be turning to all of the time in After Effects. All right, let's talk about green screen. Green screen's something that at some point you are going to want to do in After Effects. So let's take a look at this example really quick. You can see that down here, my timeline, I actually have a precomp, and let me jump in here first and show you what I have going on in my precomp. All right, so this is my precomposition, the reason why I did it this way is because a lot of times when you are footage which is what this is called. You don't need to deal with the entire green screen or maybe you're not even shooting on an entire green screen. This could be like a small portable background on somebody. This is not a green screen tutorial but let me show you some of these great effects here. The first one that I have applied is called selective color and I'm using that to juice up this green color. Because you can see, without it, this green is very, very dull. So sometimes, using a tool like Selective Color can be used to juice up the background and help you pull a little bit better of a key. Not always but it's an option, just wanted to show you that there. Then I'm using a really simple key effect, it’s called color key. You can see if I turn on the transparency grid, we are getting some transparency there. I’m just gonna turn that off because that’s just a little bit too busy for me. Now color key is not an effect you would use to key this entire image. If I jack this up all the way to where it’s playing all of the green, you can see that's just not gonna work. What I'm doing instead is I'm using it to essentially give me a garbage mat. Instead of drawing a mask around my guy here and animating it so that his hands don't go out of the mask which could be done and often is done. That's too much work for this particular application and can be done very simply with a few effects like color key and I can throw another color key on here with a little bit different of a shade. And another one and get essentially 97% of all the green pixels out of here. And you can see there's a little bit of jazz left over and it did make a real mess of the edge here, and that's what I'm using Simple Choker for. Which does a little matte choking and helps me to create a nice, little edge here. And so now all I have to do is deal with the edge around my guy, much, much easier. So when I jump back to this comp here, I'm using three very powerful effects. The first one is keylight. So keylight is doing the key and it's a much more advanced key than color key. It's got a ton of options, way more than I have time to go into right now. And so that is giving me a nice key around my guy here, and it's not completely destroying the edge. You can see when I turn that on, it's doing an all right job. And most of the settings are actually left at their defaults. One major thing I wanna draw your attention to is I changed this from final, which looks like this, to intermediate. Final result in keylight, does a little bit of color correction and edge clean up here. And I don't wanna do that because there's a better way to do that in After Effects. The next effect I'm using is called key cleaner. Now watch what happens to the edge here. Let's look down here. I'll undo that and put it back. And see that key cleaner is doing a couple things. It's filling in some holes. You can see that I did have a hole punched through this guy because he's wearing some kind of thing-a-ma-jig on his wrist. I don't know if that's a compass or who knows, but it is reflecting the green screen. And so that is punching a hole, you can see my fancy magenta background here. It's fixing up some holes. It's also cleaning up this edge. Now, I was looking at 200% which can be dangerous when you're doing keys. You can see down here, I do have some transparency issues. So Key Cleaner is helping with that. It's not perfect, it could still use some tweaking but it's getting me most of the way there. And finally, I have just gonna roll back to another frame here. So you can see I have advanced spill suppressor, if you look carefully, you can see on my guy here at the very edge. There's a little bit of green bleed coming from the light from the screen that's bouncing back, it's hard to see. You can see if I zoom way up to 800%. There's a little bit of green there. Advanced spill suppressor fixes that. There's definitely more to explore there with Chromacam. But I did just wanna touch on these very very useful tools, and those will get you really good results. All right let's talk about generate. I threw together a composition here with a handful of effects that are under the generate heading, or the generate folder if you will and all of these generate something. So for example, in this first layer here, the first effect that I'm using is called fractal noise, and it generates a fractal noise pattern and there's a bunch of different options here. Fractal noise is one of those effects that can be used for so many things in After Effects, you can use it for all kinds of different effects to drive animations or to just create a background for something. If you're curious, just look up some fractal noise tutorials and you'll find a bunch of great stuff that you can do with fractal noise. I'm using in this case to just generate this fractal noise using a dynamic fractal type. The default is kind of this I don't know just kind of staticy noise looking thing, but I change it to dynamic because make this kind of gloomy sort of noise pattern. Then I'm using a color collection effect called colorama to give it this colorization here. Finally, I'm using a tint effect to knock down the saturation just a little bit. And I did this just to show you one thing you could do with a fractal noise, is you can make this kind of, I don't know, lava texture here. And you can animate this. Fractal Noise is a great effect. It's worth exploring and it's worth looking into for all kinds of really cool effects that you can use it to build on or just use it for a background. All right, what do we have next? Gradient ramp, very simple effect. Now you know if you've watched the shapes lesson, you can make gradients using a shape layer. However there's lots of times when it may make more sense to use a solid and this effect called a gradient ramp which generates a linear gradient or a radial gradient. One of the things that I like about this effect that shape layers does not have is if I zoom in really tight you can see that there's a bit of noise in here and that's done on purpose. There's a option here called ramp scatter and that essentially takes a noise pattern and mixes that in to your gradient and you're thinking, why would I want to do that? I mean that looks gross and yes, that much ramp scattered does look pretty gross. However, when you're working on compositions in eight bit per channel, there's only 256 shades of gray that you have available. That's what eight bit is. There's only 256 levels in eight bits. And so if you're using a gradient, you will often see banding, where you'll get these kind of lines. And you're probably going to see it in the compression. I don't see it on my screen but I can see it in my screen recording software that it is banding a little bit. And then when this gets compressed for the web, you may see that even greater. So one of the ways you can get rid of that is by using a ramp scatter here, right on the gradient. You can do this another way. You can use a noise on top of this, however, this is built right in, it renders very fast and it just works. All right, what do we have next? We have the 4-Color Gradient effect. This is a really nice effect here. It's got a ton of animateable features. And again, when you're looking at these effects, treat them as building blocks. You don't see this and go, man, that After Effects, this is the best thing I've ever seen because honestly, this is not that great. But you can see, you could create a really nice ambient background. If I set the other colors to some kind of oranges and reds, and animated this yellow here around. You can create kind of a nice, ambient, cool looking background you can put behind some text or something. Lots of different options for these. All right, how about the checkerboard effect? This is great for all your checkerboard needs and you can change this and modify this to do all manner of creative things, from checkerboards to different checkerboards, I'm just kidding. Tons of stuff you can do with this. You can feather the south, feather the height and the width and use this drive other effects are just great and interesting background. All right, lets look at grid. Grid's another basic effect for lots of different line and grid type needs. You may not always need a grid or a grid that looks like this, but there's lots of different ways that you can use this grid. For example, maybe you just need some, I don't know, some vertical or horizontal lines. Well, no problem, look at that, boom. I doubt you could do that faster with shape layers than what I just did there. Now, this doesn't work like shape layers because this is not continuously. If I increase the scale of this, it'll get pretty nasty looking. However, for a lot of things this is quick and it gets the job done. And you can use multiple instances of this grid and change the border in the blend mode to get a really nice looking grid or a line pattern. It's very cool. And finally, and this is not finally for the generate effects because you can see there's a heck of a lot more that I'm not gonna get into. I wanted to show you this scribble effect because I think it's pretty cool. This scribble effect is on a solid. All of these are black solids and I've created a basic path here. And if I just preview this for a couple seconds, you can see it has this kind of wiggle, kind of scribble effect which is pretty cool. Lots of different options on how this looks, and the color, and the thickness, and the angle. You can make it look just how you want for all kinds of creative, scribbly stuff. You can also throw a stroke over top of this which is another generate effect. It's right here, and you can use this stroke effect and set it to Reveal Image. And check this out. You can do kind of a ride on for this stroke. There's lots of different ways to do ride on effects inside of After Effects. This is just one of them and it's pretty cool looking. So you can animate this and you can animate your path and you can come up with all kinds of creative stuff to do with these effects. Coming up in the next lesson, you're gonna learn about some absolutely incredible-looking third-party effects. Some of them cost money, some of them are free, but I'm going to show you some of my favorites, coming up next.
