You can see here the mask created in the first node uses a combination of a qualifier and power window to isolate the sky (you can tell by the small icons which appear in the bottom right corner of the node), this mask has created a key. This allows you to perform operations to areas of the image, inside and outside the mask, in two separate nodes. Outside NodesĪn outside node is an easy way to invert a selection mask into another independent node. By right clicking the links and deleting them, you can re-order connections by dragging from the parallel node outputs to the desired layer mixer node inputs in whatever order you require. It is important to note that Resolve treats the bottom most connection as the top of the layer stack, this can seem a bit counter-intuitive to begin with but you quickly get used to it.
An additional input to the mixer node (either parallel or layer) will automatically be created each time you add another parallel node. You will see options to morph a parallel into a layer mixer node, or vice-versa, and to add additional inputs and outputs. You can modify a parallel or layer mixer node just by right clicking. This layering function allows the outputs of multiple nodes with keys to be layered in a particular order. While a parallel mixer node is automatically added with a parallel node, and will mix the outputs of two or more parallel nodes regardless of the order they are connected to it, a layer mixer node will layer its output according to the order of the nodes connected to it. The output of these two nodes feeds another type of node, known as a parallel mixer node.Ī parallel mixer node simply combines the outputs of two (or more) nodes into a single output, regardless of the order they are connected in. When you add a parallel node, you will notice a new node appears below your existing node, both sharing a common source input. Parallel NodesĪ parallel node is a little more interesting. It is the basic building block on which most functions and operations are assigned. The serial node is the most common and basic node. This means it can be connected in a sequence, taking its input from the output of the previous node, and feeding its output to the input of the next sequential node.
Serial NodesĪ serial node has one input, one output and can be connected in series linearly with other nodes. Both connection points will always be present, but both will not always be in use. From this point on, you can assume that both RGB and key are being referred to as one input or one output. The RGB node input and outputs are marked by small green circles, the key input and outputs are marked by small grey triangles. A key input / output is used for a key channel. An RGB input / output is used for image RGB channels. Node Inputs and Outputs (RGB and key)Īll nodes have two types of input and output. It is a very powerful way of breaking down complex operations. A node is inherently sequential in its behaviour, making a change and passing the result on to the next node.īy dividing operations up logically, into a sequence of nodes, we can maintain control over even the most complex combination of processes. A node takes the image information it receives at its input, applies some combination of operations, and presents the resulting image at its output. What are DaVinci Resolve Nodes?Ī node is a fixed point in the image processing pipeline, a container where one or more operations or functions are applied to a part of the image-or to the whole image itself. Once you know the different types of DaVinci Resolve nodes, and how they function individually and together, you’ll be able to construct any grade you can envision.
To utilise the full power of DaVinci Resolve, you really need to know how to get the most out of the DaVinci Resolve nodes.
