How To Build Your Own ‘RGB Crosstalk Curves’ Node Matrix

Visual Math Part 7 – Rebuild and supercharge Resolve’s RGB Mixer

In this Insight you’ll gain a clearer understanding of Resolve’s RGB Mixer and 3×3 matrices by rebuilding their functionality with splitter/combiner nodes — but that’s just the beginning! Armed with this new knowledge, you’re going to explore a more nuanced matrix manipulation technique we wouldn’t otherwise have access to — which I like to call Crosstalk Curves.

AND since this is our last Insight in this Visual Math series (for now, at least), I leave you with some additional ideas for expanding this matrix toolkit even further on your own.

What is a matrix?

No, we’re not talking about Neo and his choice of taking a blue pill or a red pill (but if you follow along, you may find yourself awakened to a level color grading possibilities).

The matrices you’re learning to build in the node tree are one of the most versatile and powerful tools in image science. Normally, our interaction with matrices in Resolve is limited to the RGB mixer, which offers only one particular type of matrix.
