Chapter 5 - Video setup
5.2 Colour bars
The color bar switch is used to switch a standard test signal that can be used to set up and
check the camcorder.
The internal test signal generator produces standard SMPTE color bars. When switched on, a
standard 1 kHz tone can be enabled which is routed directly to all four audio channels. Go to
the
AUDIO > SETUP > TEST TONE
to enable or disable the test tone. Both the color bars and
tone can be recorded. The test signals are also available at the BNC and audio output
connectors.
When the color bar test signal is switched on, the following functions are temporarily switched
off:
– Black stretch
– White clipper
– Zebra
– Safe area (viewfinder)
– Cadre (viewfinder)
The lens iris closes automatically when the color bars are switched on.
