AE教程 实拍绿幕抠像合成视频教程 细节更好处理方式

在本期After Effects教程中，我们将看看如何有效地处理在After Effects绿布抠像的问题。
在抠像中常常要处理很多细节上的问题，如阴影、运动模糊、头发、绿色溢出等问题…

In this After Effects tutorial we’ll go over how to effectively deal with all of these problems using some advanced techniques in After Effects. In a production environment compositors often have to key greenscreen footage that was shot in less than Ideal conditions.Things like shadows motion blur long hair and green spill can make keying very challenging. We’ll start off by evaluating the footage and planning how to tackle the shot. We’ll go on to separate our key into multiple parts: making edge mattes a core matte and fixing problem areas with holdout mattes. We’ll then use a powerful technique to fix edges, color correct the character to fit into the scene, and create a light wrap from scratch. Then as a final touch we’ll add a magic blast effect. When you’ve completed watching this After Effects training you’ll have a set of tools in your back pocket that will help you to get great looking keys from even the most difficult green screens.
