Use the Modular Keyer to pull a key and selectively colour correct a clip. The processing pipeline provides an environment in which you can select and arrange the keying tools. You can select from an array of tools to create your key:

• The 3D Keyer, which provides automatic noise reduction, a 3D histogram to view the colours in a clip, and methods to refine the key. See 3D Keyer.
• The Keyer, which can be used as an alternative to the 3D Keyer, to key images by extracting a single colour or a range of colours, or by setting the luminance. See Keyer.
• The Master Keyer, another alternative to the 3D Keyer, to refine keys by gesturally modifying the matte, removing colour spill, blending edges, applying patches, and removing grain. See Creating and Refining a Key.
• The 2D histogram to adjust the luminance of the matte.
• Garbage masks to reveal or hide explicit parts of the matte. You can also use the Tracer to key difficult images. See Garbage Masks.
• Colour suppression and edge correction tools.
• Colour correction, including the Colour Warper, a tool for performing localized colour correction.
• Degrain and regrain tools.
• Difference matte.
• Containers for doing multilayered mattes and colour corrections.
• Logic operations to blend the components of matte layers.
