Vectorscope Display - Blackmagicdesign ATEM Production Studio 4K Installation And Operation Manual

Choosing this twin view makes it easy to identify similar items in the luminance and composite
waveforms, and if more blur or chroma is observed in the composite area, the item has color. If
some part of the video image is neutral gray, then it should look the same on both waveforms
because no chroma will be present. With the twin view, you can look around the waveform and
see the levels of color or chroma of various objects. Now you can see if specific objects in the
video image are color or black and white. You can make technical and creative decisions using
the Waveform Display.
When the Waveform display is zoomed in, you can toggle between COMP and B/W, and view
the same region of an image in the zoomed display.

Vectorscope Display

The Vectorscope Display uses a vector view to show the colors in a video signal. You can see
color bar video levels by using the color boxes in the graticule. All you need to do is select 75%
or 100% color bars, depending on the standard of color bar test signals used in your facility!
Some people think you can use a vectorscope to check for illegal levels. However this is not
correct and the Parade Display should be used, and set to RGB, 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
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.
Vectorscope Display
Vectorscope Display is also perfect for color grading, as you can easily see if your video is
correctly white-balanced or if there is a color tint. If your video has a color tint, the Vectorscope
display will drift off-center, and you might see two center dots. Normally the blanking in the
video signal will create a dot in the center of the vector scope, and this is because the blanking
in the video is black video without any color. Blanking provides a useful reference point to help
recognize areas of black video without any color information.
If your video has a color tint, you should see the blacks move off-color and off-center. The
degree of shift represents the amount of color tint in your video and you can see the shift in
both the white and black details of your video. This makes Vectorscope Display valuable for
removing color tint and regaining correct white balance.
