For a given channel/source, select the desired Measured Color Gamut Data (MCGD) file represent-
ing native "uncorrected" colors to use as a reference for calculating target color processing. MCGD
files are defined in the Admin: MCGD menu.
Identifies/sets the special color processing called Target Color Gamut Data (TCGD) established for
a given presentation.
Identifies/sets the method of color decoding for the current source. Default = RGB for all DVI
sources. Default = YCbCr for all cinema sources (i.e., SMPTE 292 A or 292 B ports).
Identifies/sets the desired gamma (a.k.a. "de-gamma") correction needed for proper tonal range of
the source material—for example, a grayscale test pattern will be neutral and smoothly graduated.
A "Complex Look-up Table" retrieved from internal electronics. No information available.
Applies the pull down sequence, which is typically a 2:2 Pull Down sequence. Pull down is used to
distribute file content to video. Since film is projected at 24 frames per second and video typically at
60 pictures per second, the film content must be converted to video for optimal display.
Identifies and sets the frame offset from Fields 1 to 5.
Use the drop-down menu to select the field offset polarity.
Enable to use anamorphic lens Re-Sync: Enable/disable
with this channel (disabled if re-synchronization.
anamorphic lens not installed).
Change Icon: Click to

channel.
Reset channel settings
back to factory defaults.
LUT-CLUT: Complex color
look-up table - applies a 3-
dimensional color cube for
increased color accuracy.
Not available when using a
pre-defined PCF file.
