抠色，也被称为色度键，让你拍摄的前景现场，并把它插入到几乎任何背景;这样可以节省你的钱，让你创造投篮机会是不可能的，或高度危险采取的单杆。它是有效的，关键在于细节。在这个过程中，马克·克里斯蒂安森展示了如何在After Effects制作故事片品质按键适合以及在他们的新场景，同时保留了微妙的细节，无论是股毛或软或半透明的边缘，这使结果可信。
Color keying, also known as chroma keying, lets you shoot a foreground scene and insert it into virtually any background; this can save you money and allow you to create shots that are impossible or highly dangerous to take as a single shot. For it to be effective, the key is in the details. In this course, Mark Christiansen shows how to produce feature-film-quality keys in After Effects that fit well within their new scenes, while retaining the subtle details—be they strands of hair or soft or translucent edges—that make the results believable.

与键控过程的简要说明开始，马克带你穿越参与创建一个完美的绿屏关键的步骤：产生粗糙无光，消除色彩溢出和雾面线，和炼油问题的边缘。他演示了如何使用按键光和Primatte，二者缺一不可键控工具工作在After Effects，并说明何时使用一个比其他。而对于在绿屏将无法正常工作时，他展示了如何生成高对比度遮罩，或亮度键，根据视频中的亮度数据。最后，了解压缩和如何来准备打一枪换键控。
Beginning with a brief explanation of the keying process, Mark takes you through the steps involved in creating a perfect green-screen key: generating a rough matte, eliminating color spill and matte lines, and refining problematic edges. He shows how to work with Keylight and Primatte—two indispensable keying tools in After Effects—and explains when to use one over the other. And for times when green screen won't work, he shows how to generate high-contrast mattes, or luma keys, based on the luminance data in your footage. Last, learn about compression and how to prep a shot for keying.
