You can display a new processing pipeline by replacing the default Master Keyer node on the Matte branch with one of the following nodes:
You can also reset the processing pipeline you used when you first opened the Modular Keyer.
The default processing pipeline composed of a Master Keyer node does not require a Colour Curves node because the node is set to bypass the Colour Curves node by default. If a different Keyer node is selected for the start mode, it is connected to the Matte branch only and the Colour Curves node is added to the Front branch. You can use the Colour Curves node to remove colour spill from the front clip, or perform a hue shift, for example.
