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 266
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.
When a source is properly calibrated, the trace from the different colored segments of the color
bars displayed will fall right inside their individual targets (see Figure 267).
