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.
