The Gnomon Workshop - Tracking & Compositing VFX for Film & TV

2D 与 3D 技术：使用 Nuke 与 SynthEyes，讲师 Zachary Goodson

在这个合成工作坊中，VFX 艺术家 Zachary Goodson 涵盖了为电影和电视创建快节奏视觉效果时所需的一些基础和核心工具。在七节课中，他针对一个 2D 眼睛发光效果，讲解了专业的 2D 跟踪、稳定和转描。本工作坊中教授的确切方法，正是制作中用于创建发光眼睛效果的相同工作流程。工作坊中展示的后续镜头是一个绘制移除的招牌替换，这是电影和电视视觉特效中非常常见的需求。

艺术家经常被要求移除标志以规避版权问题，甚至插入付费在特定节目中做广告的标志和品牌。Zachary 揭示了专业艺术家如何使用 SynthEyes 处理 3D 摄像机跟踪。这包括如何在 SynthEyes 中进行 2D 跟踪点以获得稳定准确的摄像机解算，如何在 3D 场景中放置平面以便在 Nuke 中合成，以及如何准备导出到 Nuke。导出后，他展示了如何使用 3D 摄像机来稳定、准备和清理一个镜头的干净背景板，包括添加多个招牌替换。他仅使用一个摄像机跟踪和 Nuke 中一个巨大的 3D 扫描线修补，就完成了所有的绘制移除和招牌替换。

本工作坊中展示的技术、技巧和方法广泛应用于电影和电视的视觉特效中。它们快速、高效，非常适合在紧迫的截止日期下完成镜头。所有可用的 Nuke 工程文件、SynthEyes 文件、PNG 标志元素和素材都作为可下载的项目文件包含在内，供进一步练习并帮助艺术家跟随课程学习。

2D & 3D Techniques using Nuke & SynthEyes with Zachary Goodson

In this compositing workshop, VFX Artist Zachary Goodson covers some of the basic and fundamental needs and tools used when creating fast‑paced visual effects for film and television. Over seven lessons, he tackles professional 2D tracking, stabilizing, and rotoscoping for a 2D eye‑glow effect. This exact method taught in this workshop was the same workflow used to create glowing eye effects in production. The following shot featured in the workshop is a painted‑out sign replacement, which is a very common requirement in visual effects for film and TV.

Artists are often asked to remove logos for copyright issues, or to even insert logos and brands that pay to be advertised in specific shows. Zachary reveals how professional artists handle a 3D camera track using SynthEyes. This includes how to 2D‑track points in SynthEyes for a solid and accurate camera solve, how to place planes in the 3D scene for compositing in Nuke, and how to prep the export for Nuke. After exporting, he shows how to use the 3D camera to stabilize, prep, and clean‑plate a shot, including adding multiple sign replacements. He teaches all the paint‑outs and sign replacements using only one camera track and one giant 3D scanline patch in Nuke.

The techniques, tips, and methods featured in this workshop are widely used in visual effects for film and TV. They are fast, efficient, and great for getting a shot done under a tight deadline. All working Nuke files, SynthEyes files, PNG logo elements, and plate footage are included as downloadable project files for further practice and to help artists follow along with the lessons.
