拉从绝密的关键是任何排序的基本技能之一,但只有最熟练的艺术家才可以的假象提取绿色屏幕元素的集成与其他 CG 图层,使它看起来像它被枪杀在同一时间、 同一台相机与镜头下相同的灯。为排序有看到很多比只是绿色像素和一个 alpha 通道。绿屏或蓝屏的拟订需要精细的艺术眼光和方法学的心态。

教授维克托 · 佩雷斯设计了这两部分课程教你所有可用的密钥工具在 Nuke X 和如何使用它们来拉作为一个真正的亲的关键。后学在第 1 部分和潜水到使用的工具和如何显示技术的理论课程,维克托生成第二部分在 Nuke 十 '的艺术和科学的绿色屏幕键控,部分 2'、 大键包含五个多小时的教学素材文件 (可用于我们的保险费会员)。

Title: FXPHD – NUK240 – The Art and Science of Green Screen Keying, Part 2

Info:
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 two of the course, Victor builds upon the theories learned in Part 1 and dives into using the tools and showing techniques on how to get great keys in Nuke X. ‘The Art and Science of Green Screen Keying, Part 2’ contains over five hours of instruction as well as footage files (available with our premium membership).
