Fader

The Fader is used to manually perform a wipe or dissolve transition. Move the Fader handle from one limit to the other to perform a transition.

Transitions

The progress of the transition is shown on the Progress Bar to the left of the Fader handle. As the Fader handle moves from one limit to the other, the Progress Bar indicates the progress of the transition.

Positioner

The KM-H3000 has a joystick positioner for positioning wipes, patterns, and washes. The KM-H2500 does not have a positioner.

Selecting Colors

Functions such as mattes, and Panel Glow have options for adjusting the appearance of a selected color. Individual adjustments for colors are:

•Luminance

•Hue

•Saturation

Luminance

Luminance affects the brightness of the video signal. Increasing luminance gives a brighter color while decreasing luminance gives a darker color.

Hue

Hue controls the shade of color (red, yellow, green, blue, etc.).

Saturation

Saturation affects the vividness of a color. Increasing saturation produces a more vivid color while decreasing saturation produces a less vivid color. Fully decreasing the saturation produces gray.
