The Waveform Monitor
The DV Rack Waveform Monitor, as its name implies, converts video signals to a
viewable waveform representing light, dark, luminance and saturation levels. It
allows you to see what you are shooting more accurately than the human eye. You
can evaluate the light and dark parts of your scene and use that information to
make adjustments to your camera in real time to improve the accuracy of the
video your camera produces.
The naked eye, viewing video on a monitor, is not a very reliable source of
information about your video signal. Our eyes and brain make adjustments to
what we see, making us unconsciously forgiving of poor lighting.
To make matters worse, the viewfinder and LCD screens found on many
camcorders do not accurately reproduce colors, brightness and framing. Some of
these LCD screens are little better than those found on a Game Boy®.
The Waveform monitor allows you to see what is happening with the light and
shadow in your picture in a more objective, consistent and measurable way. It
shows you exactly how white your white is and how black your black is, enabling
you to determine the best exposure and lighting for every situation.
Your video signal is represented in
green under an orange colored
grid called a graticule. The grati-
cule provides a means of
measuring different aspects of your
video signal.
Signals at the bottom part of the
scale are the dark parts of your
image.
