Vectorscope Display
The vectorscope display uses a vector view to show the colors in a video signal. Depending on
the standard of color bar test signals used in your facility, select either 100% or 75% from the
‘set’ drop down menu in Blackmagic SmartView setup.
Some people think you can use a vectorscope to check for illegal levels, however this is not
correct. The Parade RGB display should be used for checking for illegal colors. The reason you
cannot use a vectorscope to check for illegal levels is that both chroma and luminance values
are required. For example, colors near the white or black points in video cannot be as saturated
as the much stronger colors, which can be used in the mid-grays. Because vectorscope display
only shows colors, and not luminance values, it cannot be used solely to check for illegal colors.
Vectorscope display is the best tool for checking color levels from older, analog videotape
where you need to adjust chroma levels. Just play back the color bar segment of the videotape,
and then adjust the chroma and hue settings to set the colors of the video within the square
boxes in the graticule.
