Delve into the world of motion graphics, keying, and compositing in After Effects CC. In this course, Ian Robinson lays out six foundations for becoming proficient with After Effects, including concepts such as layers, keyframe animation, and working with 3D. To help you get up and running with the program, the course begins with a project-based chapter on creating an animated graphic bumper. Next, explore the role layers play in compositions and find out how to add style to your projects using effects and graphic elements. Last, see how to build 3D objects with CINEMA 4D Lite, as well as stabilize footage, solve for 3D cameras, and paint in graphics with the Reverse Stabilization feature.
Now whenever you go to key footage, whether it's green screen footage or blue screen footage, inevitably, some of that background color will end up bouncing back and illuminating different sections of your model. So, a lot of times you have to use spill suppression. Now, if you're joining me from the previous video you may recognize the fact that I did just turn on advanced spill suppressor, and that was pretty much it, and most of the time, when you're working with the preset that we worked with before, that's going to be the case.
If you're not joining me from the previous video, let me just show you really quickly. In the Effect Presets panel, if you under the Animation presets, in the Image Utilities folder, down under there you'll find the Keylight Advanced Spill Suppressor preset. When you double-click. Here I'll go and select layer one. It'll automatically apply three effects. The keylight effect, the key cleaner ,and the advanced spill suppressor. Now by default, these top two will be on, and the bottom one will be off. I'm at 100% magnification, I'm going to go and press the space bar and move up so we can see the top of our model's hair, and you can see there's a little bit of green there.
I'm just going to scroll up on my mouse wheel to zoom in. And here you can see the green bleed that's actually happening. Now, if you open up the Ultra Settings here. You see there's an option for Key Color. And look what happens when I go ahead and enable that effect. The green color has gone away, and her skin tone looks pretty darn good. Now, this key color is automatically linked, to the keylight key color that we set earlier, when we actually double-clicked the preset. If we open up Keylight here, you can see it keyed green.
It's just trying to key off of a lighter green color. Should you ever want to have more control, you could change the method from Standard to Ultra. Now I generally don't recommend doing this because, this is designed specifically, if you're using the ultra key or plugin from Premier Pro. Now, since we didn't use that, all we have to do was make sure that we were in the standard method, and just increase or decrease the suppression amount, to kind of mix in how much suppression is involved. Notice when I increased or decreased the color, it actually popped the key color there, just letting me know that green was the original color that was linked out there.
So if we change this to ultra, ultra gives us the actual key color that we used, which had already been linked to the key light key color. And here, you'll notice her skin tone, her model skin tone, has changed drastically. Here, I'll switch it from Standard to Ultra. And so here, what I would need to do is actually go ahead and go through some of the different adjustments to see, you know, how to bring her skin tone back. So, you can desaturate it, or increase the saturation, you get the idea.
You want to go through the different settings, to actually refine this adjustment, if you want more finite control. Now, tolerance just increases or decreases the amount of green that it's trying to pull out. So if you decrease the amount, it's going to make the effect a lot less. Desaturate controls the amount of saturation. The spill range increases that range of the color tolerance, and the spill color correction, will actually allow you to do a little bit of color correction on top of the actual spill suppression that's actually happening.
Now again, since we didn't use the ultra keyer, I'm just going to set this to Standard, because it did a really good job of keeping our skin tone, while actually removing the green screen color. When you go to use the advanced spill suppressor, I do recommend using the preset in your effects and presents panel. It's under the Image utilities folder down there under the key light, with the advanced spill suppressor.
