Let’s start in NUKE 12.2 - 04 Understanding Premults & Alphas in NUKE

In this tutorial, you will learn the concept of Premultiplication in Compositing. You will learn how to stencil out backgrounds with the help of an Alpha channel and what the NUKE Merge Node wants to have as input. Also, we talk about different Merge Operations and why it is so important to know when to unpremult and to premult - for example with Color Corrections. These topics are covered: Project Settings Reformat a Plate Generating a colored Background Merging FG & BG Merge operations Mathematical Operations in Merge Why is Premultiplication important? Radial Node Adding Postage Stamps Using Merges Understanding Multiply & Plus Premultiplication by hand Dot Nodes Premult Node / Unpremult Node Premult Alpha / Straight Alpha Color Correction needs Unpremult Preventing Color Correction Artifacts Node Clones You find the files for this lesson on my Gumroad (free) and on my Patreon!
