Video Process
The term “video process” is applied to adjustments to the
luminance and hue of the input video signal.
There are two types of adjustment, depending on the
application:
• Adjustment of an individual input signal
• Image effects on a particular bus
These types of adjustment may be carried out
independently. However, since they are implemented by
the same hardware, if the same signal is subjected to
processing twice, there may be limitations on the range of
effects obtained in the final result.
Video Process Adjustments for Each
Input Signal
For each signal input to the switcher, you can set video
process on or off and set the parameters (Video Gain, Y
Gain, C Gain, Hue Delay, and Black Level) in the Setup
menu.
For details of the settings, see “Signal Input Settings” in
Chapter 20 (Volume 2).
Video Process Adjustments on a
Particular Bus
Buses to which the adjustments apply
For each of the following buses, you can switch video
process adjustments on or off, and adjust the parameters.
• Following buses in the M/E-1and PGM/PST banks
- Key fill buses for keys 1 to 8
- Background A and background B buses
- Utility 1 and utility 2 buses
• Frame memory source 1 and frame memory source 2
buses
• Aux 1 to 48 buses
These settings also apply to keyframes and snapshots.
Making the adjustments
Adjust VIDEO GAIN, Y GAIN, BLACK LEVEL, C
GAIN, and HUE DELAY in the following menus.
Video Process Memory
When using video process adjustments for an image effect
on a bus, this function saves the final values for each pair
number for the signals. The video process on/off setting is
not saved.
When you change the adjustments the values are
automatically saved, and these last values are recalled
when the pair number is selected.
In other words, by switching video process memory on,
regardless of the video process information for each bus,
you can carry out video process adjustments for each input
signal.
The parameters saved are as follows.
VIDEO GAIN, Y GAIN, BLACK LEVEL, C GAIN,
HUE DELAY
Switch the video process memory on or off in the Setup
menu.
For details of setting operations, see “Settings Relating to
Keys, Wipes, Frame Memory and Color Correction (Key/
Wipe/FM/CCR Menu)” in Chapter 20 (Volume 2).
Video Process Settings
This section describes operations on the M/E-1 and PGM/
PST background A and B buses, and utility buses 1 and 2.
For these operations, use the Misc >Video Process menu in
the respective operating bank.
For video process settings on other buses, see the
following.
