Video output (encoder output) signal adjustments
After this system has been connected, the video output signal (ENCODER OUT) must be
adjusted if AB roll editing (editing using two source machines) using an editor, for instance, is
to be error-free and accurate. (This adjustment must be repeated when one of the connect-
ing cables has been replaced and whenever the connections are changed.)
The adjustment procedure using this unit is outlined below.
1
Check the connections. (see page 23.)
2
Set setup menu No. 10 (ENCODER SEL) to “LOCAL”.
REMOTE: For adjusting the video output signals using an external encoder remote
controller.
LOCAL: For adjusting the video output signals using this unit.
3
Adjust the source machine independently.
3-1 When using the preset values
Set the PRESET/MANUAL switches of the VIDEO OUT LEVEL, CHROMA
LEVEL, BLACK LEVEL and CHROMA PHASE controls to PRESET.
3-2 When adjusting the video output signals without using the preset values
1 Play back a cassette tape on which standard colour bar signals have been
recorded.
2 Adjust the controls in such a way that the waveforms on the waveform monitor
(WFM) and vectorscope (VSC) resemble those shown in the figures below.
A
Black level
Adjust the control to eliminate deviation.
B
Video level
Adjust this level to 700 mV.
C
Chroma level and chroma phase
Adjust the two controls in such a way that the light spot of the vector wave-
forms comes inside the rectangular grid mark.
