iDPM Lighting Menu
Video Aspect — adjusts the percentage of defocus applied to the vertical and
horizontal axes of the image.
NAM Ratio — adjusts the level of luminance at which the Defocus effect will
be applied to NAM pixels. This value applies to both NAM + and NAM -
modes.
NAM Matte Pane
NAM Matte On button — When selected a matte color is applied to the selected
NAM (lighter or darker) portion of the keyed image.
When the NAM Matte pane is activated, knob controls for matte Hue , Satu-
ration , and Brightness become available. An approximation of the color of the
matte is shown at the bottom of the pane.
iDPM Lighting Menu
The Lighting menu provides four colored light sources positional in 3D
space for each delegated keyer. Each light source can be a Point, Bar, or
Plane. The apparent reflection of the light source simulates the physics of
incident light falling on a surface, including specular effects and light falloff
due to distance and geometry. The lighting parameters interact with one
another, permitting the creation of subtle effects, and are keyframeable.
Some extremely low lighting values (particularly Light Softness ) when used
in combination with other lighting values can create visible artifacts (stair-
step aliasing). Due to the intricate lighting parameter interactions, if these
values were restricted to prevent all potential artifacts, other useful lighting
effects would be impossible. For this reason, values that might cause
aliasing are allowed. If a lighting effect looks bad, adjust the settings to
correct its appearance.
