SD Section Operations
You can use key composite effects in combining A-BUS and B-BUS
video. The portions with the key color in the video on the bus to
which the key composite effect is applied are made transparent, and
the video on the other bus is inserted as shown below.
The range of color used as the key is set with the “KEY LEVEL.”
Procedure for Using the SD Key Composite Effect
1.
Select the key composite video with the A-BUS channel
buttons (SD) (or B-BUS channel buttons (SD)).
The portions of the selected video selected with the key effect
are cut out.
2.
Tilt the video fader (SD) to the opposite side from that of the
bus selected in Step 1.
3.
Press the KEY ON Button (SD).
The button or buttons pressed in Step 1 flash. At this point, a
button flashing indicates that the key effect is being applied to
the video assigned to that button.

When using the key composite effects while the P in P effect is in use,
the key effect settings are applied to the video with the P in P effect
included.
*
Use of the A-BUS channel buttons (SD) (or B-BUS channel buttons
(SD)) while combining video with the key composite effects may result
in disruption of the video image.

The key composite effect is applied to the video selected in Step

The key level is indicated in the KEY LEVEL display (SD).
The key level can be set to any value from 0 to 255.

You can use the OUTPUT FADE button (p. 13) to fade in/out the
video from SD PGM output (p. 19).
After “6. SD Output Fader” under “6. SD Output” (p. 61) in the
menu is set to “On,” you can then press the OUTPUT FADE button
to fade out the SD PGM output over the time set with the TIME
knob. You can use the TIME knob to set the fade time in a range
from 0 to 4 seconds. If you press the OUTPUT FADE button again
after fading out the SD PGM output, the video fades back in again.
If you do not want to apply fade in/out to the SD PGM output,
set the TIME knob to 0.0.
If you fade in/out the SD PGM output using the OUTPUT
FADE button, the output of HD/RGB will also be faded.
