animation being keyed, the animation will fade out automatically after the number of
repetitions specified in the Repeat option of the keyer settings, if not faded out
manually first.
If no file has been previously selected, pressing the Keyer button a second time takes
you to the keyer’s file selection list (equivalent to the File option of the Keyer Setup
menu), from which you can select a file from among the still images and animations
stored in the unit. These images could have been uploaded to the unit from a PC (see
Appendix D, “The Uploader Software” and Appendix F, “Ethernet Control”) or
grabbed from video from the TSG/Image Grabbing menu.
The image or animation to be displayed or keyed is selected by scrolling through the
list with the control knob, and pressing the Enter key to select the desired file. The
file will be loaded, and you will be returned to the Keyer Setup menu. Pressing the
Keyer button again will fade in the file, and a subsequent press will fade it back out.
The light on the Keyer button will flash while the key is in transition (fading in or
fading out), and be lit while the key is being displayed.
See Chapter 7, “Menus: Keyer Setup” for more information about the Keyer Setup
menu.
N/R
Pressing the N/R button accesses the noise reduction functions of the unit. Pressing
the N/R button once takes you directly to the Noise Reduction menu, from which you
can configure noise reduction settings. See Chapter 8, “Menus: Noise Reduction” for
a detailed description of the Noise Reduction menu.
Pressing the N/R button subsequent times toggles the noise reduction features on and
off. The light on the N/R button will be lit when noise reduction is enabled.
Proc Amp Controls and User Keys
The proc amp controls allow the modification, storing, and recalling of proc amp
settings.
Automatic Proc Amp Setup (“Gimme Bars”)
The luminance gain, black level, chrominance gain and hue can all be automatically
set by the unit based on incoming SMPTE bars.
To use the “Gimme Bars” automatic setup mode, SMPTE bars (or other 75% bars)
must be supplied to the currently selected video input. Press and hold the Luma
button; the four proc amp parameters are automatically adjusted.
Luma
Pressing the Luma button allows you to adjust the luminance gain by using the
control knob and menu controls (see the Menu Controls section earlier in this
chapter). This is equivalent to the Luma Gain menu option in the Video Setup menu.
While setting the luminance gain, the display panel will also show the maximum
luminance level (in IRE or mV) of the incoming video signal.
Valid Range: -99.99 dB to 6.00 dB (Y/C, SDI, DV)
-8.01 dB to 4.04 dB (Composite, CAV)
Default Setting: 0.00 dB
