FXPHD – NUK235 – The Art and Science of Green Screen Keying, Part 1

从绿屏中拉出键是任何合成师的基本技能之一，但只有最熟练的艺术家才能创造出将提取的绿屏元素与其他 CG 图层整合在一起的错觉，使其看起来像是同时拍摄的，在相同的灯光下使用相同的相机和镜头。对于合成器来说，除了绿色像素和 Alpha 通道之外，还有更多可看的东西。绿屏或蓝屏的制作需要精细的艺术眼光和方法论的思维方式。

Victor Perez 教授设计了这门由两部分组成的课程，旨在教您 Nuke X 中所有可用的键控工具，以及如何使用它们作为真正的专业人士来拉动钥匙。在课程的第一部分，Victor 详细概述了每位艺术家应该了解的有关键控的概念，然后深入介绍 Nuke X 中可用的键控器。“绿屏键控的艺术与科学，第 1 部分”包含五个多小时说明和录像文件（我们的高级会员提供）。

Title: FXPHD – NUK235 – The Art and Science of Green Screen Keying, Part 1

Pulling a key from a greenscreen is one of the basic skills for any compositor but only the most skilled artists can create the illusion of the integration of an extracted green screen element with other CG layers to make it look like it was shot at the same time, with the same camera and lenses under the same lights. For a compositor there is more to see than just green pixels and an alpha channel. The elaboration of a green screen or blue screen requires both fine artistic eye and a methodological mindset.

Professor Victor Perez has designed this two-part course to teach you all the available keying tools in Nuke X and how to use them to pull a key as a real pro. In part one of the course, Victor provides a detailed overview of concepts every artist should know regarding keying and then dives into covering the keyers available in Nuke X. ‘The Art and Science of Green Screen Keying, Part 1’ contains over five hours of instruction as well as footage files (available with our premium membership).
