User Manual

You can use the arrowheads at either end of the control to fine tune your adjustments. Once
the thumbwheel has been selected either by dragging or using the arrow keys, you can use the
Left and Right Arrows on your keyboard to further adjust the values. As with the slider control,
the Command and Shift keys can be used to increase or decrease the change in value in
smaller or larger increments.
If the thumbwheel has been altered from its default value, a small circular indicator will appear
below above the thumbwheel. Clicking on this circle will reset the thumbwheel to its default.
Range Controls
The Range controls are actually two separate controls, one for setting the Low Range value and
one for the High Range value. To adjust the values, drag the handles on either end of the Range
bar. To slide the high and low values of the range simultaneously, drag from the center of the
Range bar. You can also expand or contract the range symmetrically by holding Command and
dragging either end of the Range bar. You find Range controls on parameters that require a
high and low threshold, like the Matte Control, Chroma Keyer, and Ultra Keyer nodes.

TIP: You can enter floating-point values in the Range controls by typing the values in
using the Low and High numeric entry boxes.
Checkboxes
Checkboxes are controls that have either an On or Off value. Clicking on the checkbox control
will toggle the state between selected and not selected. Checkboxes can be animated, with a
value of 0 for Off and a value of 1.0 or greater for On.

displayed in the Inspector.
