Working with the Vector and Waveform Diagnostic Displays
This section describes how to work with a vectorscope, waveform, etc. Reading this section will help clar-
ify much of the information on color and color models from the previous section and give it a concrete
basis in reality. If you’re already familiar with this topic, skip to the description of the individual color
correctors (“Primary Color Correction” on page 762 ff.).
1 Begin by importing the RGBspace.bsi test image from the directory (..\Avid
Liquid [x]\Media\Stills\NTSC or PA L) to a Project Rack. Then open the Color Correction Editor
and click the test image to load it in the editor in place of the default image. From the drop-down
list box above the Diagnostic Display, select Ve c t o r . If everything is functioning correctly, a color-
ful pattern of bands should appear on the right-hand side and the Vec t o r D i s p l ay should contain
the following image:
RGBspace.bsi test image in the Vector Display
How to interpret this image:
RGBspace contains the six hues red (R), magenta (Mg), blue (B), cyan (Cy), green (G) and yellow (Yl),
each ranging from non-saturated to saturated. These are the six lines radiating from the center point.
(See also “The Color Wheel” on page 741.)
The edges represent the different gradual transitions from adjacent hues, such as the color gradient from
red (255,0,0) to magenta (255,0,255).
About the scale: The horizontal axis is C
b
, the vertical axis is C
r
, the six markings indicate the corre-
sponding color locuses at a saturation of 75 %.
The maximum saturation of the test image colors is 100 %; this is why the corners of the hexagon are
located outside the circle.
The square contains the 75% color range.
