Tab Description
(2) It matches the response characteristics of TV sets and monitors.
• The calibration specified in video standards matches the requirements of
cameras and TV sets in broadcast use.
— This usually, however, does not match the needs of computer-based
applications or the response curves of computer monitors.
— Therefore, you often need a correction inverse to the original bias and
you may want to tune for the characteristics of a particular monitor.
• When you disable the gamma correction filters:
— Set the gamma correction value to exactly 1.00
— The software-based gamma filter works in pass-through mode with no
effect on the video and no processing bandwidth use.
— Uncheck the Gamma checkbox
• When you enable gamma correction, the text box shows the factor applied.
• If running preview video while adjusting the filter, you see adjustment
effects interactively.
• You can use one of three methods to adjust the gamma correction value:
(1) Directly enter text in the numeric text box.
(2) Click [+] and [-].
(3) Select Signal field (NTSC, PAL, or SECAM) from the options list.
• Gamma correction applies to all filters and output pins on each device.
• The gamma correction can be different for different physical devices.
NOTE: These values represent the inverses of the gamma bias that you
applied at the video source per the video standard so the resulting
video becomes gamma-neutral.
Tuning Utilities
• Access the Tuning Utilities for a selected card.
NOTE: Refer to Chapter 12: Tuning Utilities for ad
ditional diagnostics
information.
Audio Settings
• Lists the input source options for selected audio devices (Figure 110).
• Makes left and right volume levels available for adjustments if the audio
capture device supports them.
• Fields remain available whether device runs or remains idle.
