电影绿屏/蓝屏抠像技术视频教程 - FLM213 Flame for Nuke artists

这12部分的课程，教导Sam Edwards，旨在让NUKE排字加速火焰。许多课程将涵盖了以往FXPHD核课程使学生能够回到以前的课程比较的镜头。课程对比了核武器与火焰的工作流程，讨论了合成的基本原理以及火焰如何处理它们。你将在核武器中看到工具等价的工具，但特别注意火焰中独一无二的工具。
This 12-part course, taught by Sam Edwards, is designed to get Nuke compositors up to speed on Flame. Many of the lessons will cover shots created in previous fxphd Nuke courses so that students can refer back to the previous course to compare. The course contrasts Nuke vs Flame workflows and discusses the underlying principals of compositing and how Flame handles them. You'll be shown tools equivalent tools to those in Nuke, but special attention is paid to the unique tools in Flame.

这个班有三个镜头。首先是一个简单的磨砂喷漆枪，涵盖2D跟踪，旋转和控。第二个是一个更先进的无光喷漆镜头，涵盖整个3D环境的创建。拍摄任务包括从一个核文件中获取一个3D跟踪摄像机，构建几何体，应用纹理，以及从全景照片中创建一个无光泽的绘画背景。照明和渲染通行证也进行了讨论。
The class covers three shots. The first is a simple matte painting shot that covers 2D tracking, roto and keying. The second is a much more advanced matte painting shot that covers the creation of the entire 3D environment. The shot tasks include harvesting a 3D tracked camera from a Nuke file, building geometry, applying textures, and creating a matte painting background from a panoramic photo. Lighting and render passes are also discussed.

第三镜头采用CG渲染，以使多路EXR的火焰一眼盯着。它包括一个球形地图投影到三维几何创造动画纹理的CG。每一个镜头显示从绿色的屏幕画面创造最好的遮罩和抑制的一种略有不同的技术。
The third shot uses CG renders, staring with a look at bringing multichannel EXR’s into Flame. The includes a projection of a spherical map onto 3D geometry creating animated textures for the CG. Each shot shows a slightly different technique for creating the best mattes and suppression from the green screen footage.
爱德华兹在1992开始使用火焰时，他在纽约交付了第二套谨慎的逻辑系统。在那里，他从事电视广告、音乐录像和专题电影八年。在2000，爱德华兹搬到西海岸，在那里参加了一个工作在数字域，在那里他被分配到了核武器的开发团队作为一个测试排序和帮助写的内部文件。他在和其他复合膜上许多大型特效电影工作室核和火焰。今天，山姆是一个视觉特效总监和偶尔的排序在电视节目，电影，和教fxphd。
Edwards started using flame in 1992 when he took delivery of the second Discreet Logic system in New York City. There he worked on TV commercials, music videos, and feature films for eight years. In 2000, Edwards moved to the West Coast where he took a job at Digital Domain, where he was assigned to the Nuke development team as a test compositor and helped write the in house documentation. He has composited in Nuke and Flame on many large VFX films at ILM and other top studios. Today Sam is a VFX Supervisor and occasional compositor on television programs, feature films, and teaches at fxphd.
