Key Mixer: This tool helps you refine a key, the professional term that describes the process of removing something like the green or the blue of a greenscreen or a bluescreen.

Layer Mixer: These look a lot like Parallel Nodes, only with one added bonus you can control the order in which these layered Nodes take effect.

This type of Node allows you to take both of these individually-adjusted images and mix them down into one single layer. Parallel Mixer: Parallel Mixers are used when you need two Correctors to refer to the same input image, as opposed to being applied additively and on top of each other, one after the other.Whenever you adjust any of your parameters-gamma, hue, anything at all-any changes made are stored in a Corrector Node. Corrector: A Corrector is what the beginner is likely to think of first when considering Nodes in a generic sense.This element represents the output image after all is said and done. The Output Image: Finally, the right-most green dot.These are the miniature superhighways that determine what happens to the image and in what order. Links Connecting Every Node: These cables control the flow of Nodes from left to right.There are other types of Nodes aside from the ones that you use to adjust the grade-some of them act as a checkpoint where several Nodes come together, for example. Your Corrective Nodes: Each Node exists as a complete layer of color correction, as opposed to representing an individual effect (like a simple adjustment in saturation).Usually, this input will be your source clip. This is the input that all of those to follow will be modifying. The Input Clip: The left-most element in the Nodes panel, a little green dot.

There is so much to know about Nodes in Resolve, but the entire system can be boiled down to: Each Node represents a discrete step forward each subsequent operation is applied to the composite linked just before it directly. Instead, the Nodes panel is a graphic representation of all of the elements that make up your grade. Nodes exist in Resolve exclusively-they don't ever leave the application themselves. They're not really layers, and they're not really LUTs, either (although you can create a LUT from a Node if you need to). First things first: we should clarify just what exactly a Node is in Resolve.
