Setting Up the Processing Pipeline

To build your key, you can use the tools provided on the default processing pipeline as well as add tools. You can also remove tools and set up the pipeline to best suit your needs. Each tool is represented by a process node that you can click to access the node's menu.

The pipeline is made up of three processing branches—one each for the front, back, and matte clips, as shown in the following image.

Red is used for the outline of the front clip proxy and branch, green is used for the back clip, and blue is used for the key-in clip. These colours correspond to the colours of the arrow cursor when selecting clips from the desktop.

The processing pipeline is similar to the process tree of the Batch module, except that its main purpose is to create a key. Unlike Batch, most of the nodes that you use in the processing pipeline have one input and one output. This allows for a more streamlined schematic. For more information on the Batch module, see Batch Processing.

The processes on the pipeline are performed sequentially in the direction of the arrows shown on each branch. The result of each branch is fed into the Front, Back, and Matte tabs of the Result node to create the composite.

To process the composite—the output of the Result node—to the destination reel, you click the Process button in the Modular Keyer menu.

The default pipeline that you see when you first access the Modular Keyer contains certain nodes. These nodes correspond roughly to the functions of the traditional Keyer:

• On the Front branch, the CCurves node opens the Colour menu, where you can remove colour spill from the front clip, perform a hue shift, for example.
• On the Matte branch:
  • The 3D Keyer node opens the 3D Keyer, where you can pull the key.
  • The 2D histogram node opens the histogram, where you can adjust the luminance of the matte.
  • The Edge node opens the Edge menu, where you can adjust the edges of the key using shrink, erode, blur, for example.
  • The GMask node opens the Garbage Mask menu, where you can create garbage masks.
• The Result node opens the Matte Curves menu, where you can adjust the front and back mattes.

If the node for the operation you want to perform on a clip is not already on the pipeline, you add it to the appropriate branch. For example, if you want to blur the front clip, add an RGB Blur node to the Front branch.
