A Chomra Keyer node creating transparency on the MediaIn node
Inspector
Chroma Key Tab
The Chroma Key tab is used to make the initial selection of color for keying.
Key Type
The Key Type menu determines the selection method used for the matte creation.
Chroma: The Chroma method creates a matte based on the RGB values of the selected
color range.
Color: The Color method creates a matte based on the hue of the selected color range.
Color Range
Colors are made transparent by selecting the Chroma Keyer node in the node tree, and then
dragging a selection around the colors in the viewer. The range controls update automatically
to represent the current color selection. You can tweak the range sliders slightly, although most
often selecting colors in the displays is all that is required.
Lock Color Picking
When this checkbox is activated, selecting colors from the viewer is disabled to prevent
accidental addition to the range. It is a good idea to activate this checkbox once you make the
color selection for the matte. All other controls in the node remain editable.
Soft Range
This control softens the selected color range, adding additional colors into the matte.
