Learn to remove green and blue screens from challenging shots using Nuke keying tools. Build templates and workflows for spill removal, edge refinement, and hair detail preservation with luminance matching.
Apply a green screen removal workflow in nuke by denoising, creating core and edge mattes, and combining ibk color and ibk gizmo with keylight and primatte to preserve hair details.
Explore the Primatte node in Nuke to key blue or green screens, using FG, BG, and mask inputs, with spill suppression, auto compute, and detail tools for clean composites.
Use primatte to create a solid alpha core matte while refining edges and hair with ibk color and ibk gizmo, then combine edge and inside mattes for clean chroma key.
Explore the IBK keying workflow in Nuke, creating a clean plate with IBK color and refining edge matte with IBK gizmo, stacking and luminance adjustments for a clean green-screen key.
Learn to despill green spill in Nuke by comparing Keylight with Pxf kill spill, restore luminance with minus and plus merge operations, and set saturation to zero.
Explore erode, edge extend, and color smear techniques in Nuke to refine keying edges, adjust pre-mult edges, and color grade the foreground for clean edge blending.
Automate background luminance matching to the foreground by multiplying background luminance with de spill and adding alpha via a keyer, ensuring edges align with any background.
Learn to preserve hair detail in Nuke by using Keylight with key mix and roto masks, sampling Macbeth values, and tuning midtones to 0.18 for hair extraction.
master prep and roto in Nuke to mask out head portions, automate roto with the copycat node using machine learning, and composite with copy/shuffle and pre-mult spill before color correction.
Apply defocus to background and use light wrap to bias foreground edges, then compose with shuffle and merge, adjust green spill using hue correction and roto, and render with grain.
Remove tracking markers from a green screen shot with color variation by tracking, using transform mask and roto, then applying matchmove and primatte to clean the background for background removal.
Remove background markers using frame-by-frame roto painting or shoulder tracking. Refine with roto masks, premultiply to RGBa, and merge for clean edges.
Week 4 of 15 - Foundry Nuke From Zero to Hero! is the fourth course out of 15 in the zero to hero series by Sajjad Aradfar, designed to help you become a professional compositor.
This Nuke visual effects training course will take you through the fundamental concepts of VFX Compositing in Nuke. Also you will learn the steps of getting started working for major VFX companies. By the end of this mega course, you will successfully be able to do film compositing and stand as an experienced Nuke Artist.
Throughout this week I will equip you with everything you need to know effectively removing green or blue screen from the background of challenging shots. In big-budget productions, the green screen setup isn’t always perfect, and actors may not always stay within the designated green screen area. By the end of this week, you will have a strong grasp of how to handle even the toughest green or blue screen scenario. I will cover, creating a template for the green or blue screen removal process, getting familiar with keying tools in nuke, creating clean and precise matte, primary and secondary color spill removal process, hair detail preservation, automating luminance match of BG to FG, and removing tracking markers.
There will be a lot of theory you need to learn first before you can successfully composite a shot, and with anything worth learning there is a learning curve. But if you persist through you will have a great payoff and skillset at the end, and a great shot to show off that you created!
Note: You will be required to download the project files if you want to follow along with this class. this course has been created with NukeX 13.2v5
