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. 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. But I did just wanna touch on these very very useful tools, and those will get you really good results. There's definitely more to explore there with Chromacam. There's a little bit of green bleed coming from the light from the screen that's bouncing back, it's hard to see. So you can see I have advanced spill suppressor, if you look carefully, you can see on my guy here at the very edge. And finally, I have just gonna roll back to another frame here. It's not perfect, it could still use some tweaking but it's getting me most of the way there. You can see down here, I do have some transparency issues. Now, I was looking at 200% which can be dangerous when you're doing keys. And so that is punching a hole, you can see my fancy magenta background here. I don't know if that's a compass or who knows, but it is reflecting the green screen. 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.
And see that key cleaner is doing a couple things. The next effect I'm using is called key cleaner. And I don't wanna do that because there's a better way to do that in After Effects. Final result in keylight, does a little bit of color correction and edge clean up here. One major thing I wanna draw your attention to is I changed this from final, which looks like this, to intermediate. And most of the settings are actually left at their defaults. You can see when I turn that on, it's doing an all right job. And so that is giving me a nice key around my guy here, and it's not completely destroying the edge. It's got a ton of options, way more than I have time to go into right now. So keylight is doing the key and it's a much more advanced key than color key.
So when I jump back to this comp here, I'm using three very powerful effects. And so now all I have to do is deal with the edge around my guy, much, much easier. Which does a little matte choking and helps me to create a nice, little edge 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. And another one and get essentially 97% of all the green pixels out of here. 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. 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. What I'm doing instead is I'm using it to essentially give me a garbage mat. 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. Now color key is not an effect you would use to key this entire image. I’m just gonna turn that off because that’s just a little bit too busy for me. You can see if I turn on the transparency grid, we are getting some transparency there. Then I'm using a really simple key effect, it’s called color key. Not always but it's an option, just wanted to show you that there. 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. Because you can see, without it, this green is very, very dull. The first one that I have applied is called selective color and I'm using that to juice up this green color. This is not a green screen tutorial but let me show you some of these great effects here.
#Choking after effects portable
This could be like a small portable background on somebody. You don't need to deal with the entire green screen or maybe you're not even shooting on an entire green screen. 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 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. So let's take a look at this example really quick. Green screen's something that at some point you are going to want to do in After Effects. All right, let's talk about green screen. 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.
