3.5.3. Controlling the Mask Attributes

When the mask object is selected the CTRL SEL button is used to select which of its attributes (colour,
position, size, or individual edges of the object) will be adjusted by turning the shaft encoder knobs. Press
the CTRL SEL button until the desired CTRL SEL item is shown on the front panel. When you have
chosen the desired CTRL SEL item press the MASK button again or turn one of the shaft encoder knobs
to begin controlling the selected attribute of the mask. The selected attribute for control will show on the
ctrl line of the OSD.
The items that are shown in the mask CTRL SEL menu depend on the MODE settings and the settings in
the SETUP menu. In the sections describing the CTRL SEL items, the relevant settings from the mask
MODE and SETUP menus are shown where necessary.
