大家好，欢迎来到 CGCircuit 的新课程“绿屏和蓝屏键入 Nuke”。在本教程中，您将学习在 Nuke 中实现绿屏和蓝屏移除的正确工作流程和正确工具。如果您不知道从哪里开始，色度键控可能是一件具有挑战性的事情。好吧，跟随我这个实用的方法来创建一个镜头，它将教你 Nuke 色键的基本原理。
这不是，只是另一个为您提供技术工具箱的教程。在这里，您将看到如何完成拍摄。键控不是要知道如何使用 Nuke 节点。这是关于理解不同的组件及其背后的逻辑。到本课程结束时，移除蓝屏和绿屏对您来说将不再是秘密。您将获得专业的提示和技巧以及强大的工作流程。
我是弗洛里安·吉拉多。我是一名专门从事合成的高级视觉效果艺术家。我在电影行业工作了 10 多年。整个课程基于我的专业和教学经验。在第一章中，我们将介绍色度键控的理论方法。我们将看到它是如何工作的，以及达到专业结果的基本步骤是什么。然后在第二章中，我们将组合一个绿色屏幕截图。这个实际例子将使我们能够发现 Nuke 中不同的抠像工具，同时了解最常用的抠像工作流程：核心键、软键和去溢出。最后，在最后一章中，您将学习优化关键帧、修复坏边缘、重新引入头发细节和背景整合的技巧。
本课程的一些关键要点是：
-了解色度关键挑战
- 学习专业的抠像工作流程，包括核心磨砂软磨砂和去溢出
- 使用 Keylight、Primatte 和 IBK Gizmo
- 使用第 3 方小玩意
- 学习改进边缘和改进键的技术。
Hi everyone, welcome to this new course on CGCircuit, “Green Screens and Blue Screens Keying In Nuke”. In this tutorial, you’ll learn the proper workflow and the right tools to achieve green screen and blue screen removal in Nuke. Chroma keying could be a challenging thing if you don’t know where to start.

I’m Florian Girardot. I’m a senior visual effect artist specialized in Compositing. I’ve been working in the movie industrie for more than 10 years. This entire curriculum is based on both my professional and teaching experiences. In the first chapter we will have a theoretical approach to chroma keying. We will see how it works and what are the essential steps to achieve a professional result. Then in the second Chapter, we will key together a green screen shot. This practical example will allow us to discover the different keying tools in Nuke, while going through the most used keying worklfow: core key, soft key and despill. Finally in the last chapter, you’ll learn techniques to refine your key, fix bad edges, re-introduce hair details, and background integration.
Some of the key takeaways of this course are:
-Understand the Chroma key Challenges
-Learn a professional Keying workflow including core matte soft matte and despill
-Work with Keylight, Primatte and IBK Gizmo
-Use 3rd party gizmos
