Keying: View Controls

The View Controls were introduced in Primatte Keyer 3. You use them to designate what image mode you see in your composite window, and enable you to split the screen to see your keyed footage in various states simultaneously.

View Menu

While using Primatte Keyer you will need to switch back and forth between different views to accurately build your matte, and this menu is where you make your view choice. When in the Split Screen mode (see below), this menu is where you select what is seen on the left side of the screen.

There are four main components to the View menu.

Comp tells Primatte to display the current composite in the composition window. The current comp is the keyed foreground element over the background element (consisting of one or more layers in the After Effects composite). Matte tells Primatte to display the matte as it is currently being generated. Foreground will display the unkeyed, original foreground element. This mode is useful for verifying areas of the unkeyed foreground that are to be transparent, or to identify an area for spill removal later on in the keying process. Background shows the original, unadjusted background image, if one is present. If none has been added to the composite, choosing this option will display the background color.

Split Screen

One of the coolest features introduced in Primatte Keyer 3 was the ability to do a split screen view. The Split Screen checkbox toggles the split screen effect off and on. When this is enabled the split screen is visible in the composite window.

Right Menu

The Right Menu allows you to choose what to display on the right side of the comp window when the split screen is enabled. The menu options are identical to the View menu above. Unless the Split Screen checkbox is enabled the Right menu is disabled and has no function.

Amount

The Amount slider allows you to set the location of the split between left and right. The default value is 50%, which sets the split at the middle of the Composite window. Lower values move the split to the left, and higher values move it to the right.
