Chapter 5, Configuring Your DigiSuite LE and VTR Settings
–
Level
Adjusts the difference in luminance between the lightest and
darkest areas of the picture.
–
Setup Adjusts the level of black in the picture.
q
Use Automatic Gain Control (AGC)
Select this option if you want
the gain of your analog input signal to automatically be adjusted to
compensate for very bright or dark images. This improves the
brightness or contrast of your picture.
q
Source has Built-in TBC
Select this option if your analog input
signal is stable and broadcast-quality. This allows DigiSuite LE to
reproduce the input signal as-is, without degradation.
If your source device doesn’t have a time base corrector or meet
broadcast-quality standards, make sure this option isn’t selected.
DigiSuite LE will then filter the signal to increase the tolerance for sync
pulse instability.
Note
Whether or not you select the Source has Built-in TBC option,
the input signal is always processed through the TBC on your DigiSuite
LE.
q
Apply Edge Sharpening to Video
Select this option to slightly
sharpen the edges in your picture (for analog input only). The edge
sharpening is done by amplifying the high frequency component of the
video input’s luminance signal. Be aware that selecting this option may
reduce the clarity of fine details in your image.
