The Secondaries menu allows you to create and track geometries to isolate objects or areas within the shot, and create keys to isolate ranges of colour. You are then able to use logical operations to link geometries across secondaries. The following is a breakdown of the Secondaries menu.
(a) Geometry panel (b) HLS and Diamond Keyer panel (c) Secondary Layers panel (d) Shape and Point Tracker panel (e) Presets panel
Geometry panelCreates geometries of various shapes in order to isolate objects or areas within a shot. Once a geometry has been graded, you can modify the softness, colour, opacity, and blur of the geometry to acquire a certain effect. See About Geometries.
HLS and Diamond Keyer panelExtracts a key to isolate a colour within your shot. See Creating a Secondary by Keying a Range of Colours.
Secondary Layers panelCreates up to 48 layers of secondary grading for each shot. See Secondary Layers.
Shape and Point Tracker panelTracks either objects or points throughout a shot. See Shape Tracker and Animating the Point Tracker.
Presets panelLists the previously saved geometry, gmask raw, tracker, and key presets that allows you to increase the efficiency and speed of the colour grading process. See Saving and Loading Presets Using the Presets Lists.
