USING COLOR BARS
You’ll no doubt have seen the familiar color bars used as a standard reference for video signal
calibration. Two examples are shown here. Figure 221 is an example of the color bars used in
NTSC countries, while Figure 222 is a PAL example, common throughout European nations.

You can use color bars in conjunction with TriCaster’s Waveform and Vectorscope to make sure
the video supplied to the Switcher is consistent, accurate and broadcast legal.
Most video cameras are capable of displaying color bars – check your camera manual to see how
to display these (given a choice, use 75% bars). Then look at the Vectorscope to see how it traces
the individual colors comprising the image.
Figure 223
The Vectorscope graticule has six distinct rectangular targets, one each for Yellow, Red,
Magenta, Cyan, Blue, and Green. The targets are small rectangles with a cross-hair
superimposed on them.
