Video Calibration Setup
The Video Calibration tab on the Setup window contains information that is 
required to obtain an accurate video match.
Aim Settings
Enter the values for the video space you want to calibrate to (CCIR 709, 
SMPTE RP145, or User Defined). 
The default values represent a typical NTSC HD display. These values can be 
altered for a user defined video space.
White Point Chromaticity (xy) - Desired white chromaticity. Enter values 
in CIE xy.
White Patch
White Luminance (Y) - Desired white (max neutral code value) luminance 
can be measured by a colorimeter or spectrophotometer. Enter the value 
in ft-lamberts.
NOTE
Recommended practices for HD/SD video monitors place video legal whites 
at a luminance of approximately 30 ftL. Translating video 100% legal white 
(code value of 940) to a maximum monitor drive code value of 1023 (10-bit) 
yields an absolute monitor white luminance recommendation of 
approximately 34 ftL This high luminance setting may degrade the useful 
lifetime of some monitors
Dark Patch
To override the video Dark (code value) settings, check Override 
Calculated Aims for Dark Patch. The value fields become active and you 
can enter new values for Dark Luminance (Y). We recommend using the 
default settings.
