Nuke Compositing Masterclass: Keying - Part 2, Module 1

Explore screen-based keying in nuke, including manual, expression-based, simple, and proprietary keyers, compare green and blue screen, and apply production workflows with a clean plate and additive keying for composites.

Explore screen-based keying to extract a matte from green or blue backgrounds using Nuke keyers like Keylight, and apply plate prep and additive keying for realistic compositing and color grading.

Compare greenscreen and bluescreen for keying, noting how color, hue, and temperature affect matte extraction, spill, and lighting suitability across daytime warm and nighttime cool scenes.

Explore NUC keyers for extracting matte masks or alpha channels to seamlessly composite with backgrounds, including Keylight, Iebc, Primatte, custom nodes, and soft and core matte techniques.

Explore basic expression keying in Nuke to extract a raw alpha matte from green and blue screens, then refine with denoise, alpha grading, and premultiplied compositing.

Explore blue screen keying in nuke with expression keyer methods, including blue minus red and blue minus max of red and green, plus denoise and alpha grading for clean mattes.

This lecture teaches basic expression keying in nuke for green and blue screens, including soft and core matte distribution, denoise, g minus r or g minus max(r,b), and premultiply compositing.

Learn a second green screen keying workflow: denoise to refine matte, switch to green screen operation, grade alpha, premultiply, and composite with background using merge over while mitigating spill.

Apply denoise to blue screen plates and use the blue keyer to extract the matte. Adjust black and white values to refine edges before compositing with a background.

Apply blue screen keying with denoise, sample rgb channels, adjust black and white points, premultiply, copy matte, and suppress spill to composite a clean foreground over a background.

Learn denoise and advanced keying on green and blue screen plates, refine soft and core mattes with HSV adjustments, erode, and premultiply to composite foreground with spill suppression.

Apply denoise before keying to remove grain, refine with soft and core matte, then premultiply and suppress spill for clean green/blue screen composites.

Key light keyer guides green and blue screen keying, denoise and extract a clean matte, then premultiply and composite with background for seamless integration.

Learn to key blue and green screen footage in Nuke using the key light keyer, denoise, and matte refinements, then compose foreground with background via merge over and premultiply.

Learn to key and composite inside the key light using denoise, screen mattes, and in/out masks to protect edges, remove noise, and produce a clean premultiplied foreground with spill suppression.

Utilize the Keylight keyer to denoise the plate, refine soft matte and core matte, and composite foreground with background in a single key light workflow.

Learn primatte keyer, a 3d keying tool, for matte extraction on green and blue screens using denoise, auto and manual modes, with premultiply, merge with or, and spill suppression.

Use Primatte Keyer on blue screen with auto compute and denoise to generate a clean alpha matte; premultiply, merge with background, and suppress spills for a tight composite.

Explore denoise and keying inside the Primatte keyer to extract a clean alpha matte, preserve plate detail, and perform in-node keying and compositing with auto compute.

Explore primatte keyer techniques to key from a single-frame green or blue screen, refine matte with denoise and roto, then composite over background using premultiplied alpha and spill suppression.

Builds an After Effects style key workflow in Nuke using a customized keyer, green and blue screen backings, and matte refinement with denoise, alpha grade, and black point.

Demonstrates green and blue screen keying workflows in Nuke, detailing denoise, channel separation, alpha prep, matte grading, and compositing with the background using screen operations.

Learn blue and green screen keying in nuke by denoising, extracting red, green, and blue channels with shuffle, alpha grading at black/white points, and combining via screen merge before premultiplying.

Denoise the blue-screen plate, key with a shuffle-based channel workflow in After Effects to extract red, green, and blue mattes, then refine and composite with spill suppression.

Learn how to key with the IBK keyer in Nuke, compare without and with clean plate workflows, denoise, alpha refine, and premultiply foreground for blue and green screens.

Key blue screen footage using IBK Gizmo and IBK Color, with or without a clean plate; denoise, build alpha, refine matte, premultiply foreground, and composite with background, suppressing spill.

Key and composite with the IBK gizmo in Nuke, denoise the plate, refine the matte with luminance match and auto level, then blend with a background via merge.

Explore real-world keying workflows with the IBK gizmo, applying denoise, mat extraction, and roto to refine alpha, and compare performances with and without a clean plate.

Build a clean plate with IBK gizmo and IBK color to obtain a precise alpha. Then refine with roto and color controls before premultiplied compositing with spill suppression.
