Premiere Pro has a vectorscope and waveform monitors (YC Waveform, YCbCr Parade, and RGB Parade) to help you output a video program
that meets broadcast standards and also assist you in making adjustments based on aesthetic considerations, such as color corrections.
For decades, video production and duplication facilities have used waveform monitors and vectorscopes to accurately evaluate video levels—
specifically, color and brightness.
A vectorscope measures the chrominance (color components) of a video signal, including hue and saturation. A vectorscope maps a video’s color
information onto a circular chart.
The traditional waveform monitor is useful in measuring the brightness, or luminance component, of a video signal. In Premiere Pro, the waveform
monitors can also display chrominance information. The waveform monitor works something like a graph. The horizontal axis of the graph
corresponds to the video image from left to right. Vertically, the waveform displays the luminance levels, and optionally, the chrominance levels.

View a scope
You can view a vectorscope, YC waveform, YCbCr Parade, and an RGB Parade scope either individually or grouped in the Reference Monitor,
Program Monitor, or Source Monitor.
1. Depending on whether you want to view a scope for a master clip or sequence clip, do one of the following:
Double-click the clip in the Project panel.
In a Timeline panel, position the playhead in the sequence you want.
2. (Optional) Choose Reference Monitor from the Window menu if you selected a clip in a Timeline panel.
3. Choose any of the following from either the Reference Monitor, Program Monitor, or Source Monitor menu:
All Scopes Displays the Vectorscope, YC Waveform, YCbCr Parade, and RGB Parade scopes in one monitor.
Vectorscope Displays a vectorscope for viewing the chrominance in the video.
YC Waveform Displays a waveform monitor for viewing luminance and chrominance information.
YCbCr Parade Displays a scope with luminance (Y) and color difference (Cb and Cr) information.
RGB Parade Displays a scope showing the red, green, and blue components in the video.
Vect/YC Wave/YCbCr Parade Displays the Vectorscope, YC Waveform, and YCbCr Parade scope in one monitor.
Vect/YC Wave/RGB Parade Displays the Vectorscope, YC Waveform, and RGB Parade scope in one monitor.
Vectorscope
The Vectorscope displays a circular chart, similar to a color wheel, that shows the video’s chrominance information. Saturation is measured from
the center of the chart outward. Saturated, vivid colors produce a pattern some distance from the center of the chart, while a black-and-white
image produces only a dot at the center of the chart. The particular color, or hue, of the image determines the direction (angle of the pattern).
Small target boxes indicate where fully saturated magenta, blue, cyan, green, yellow, and red (present in a color bars test pattern) should
appear. In NTSC video, chrominance levels should not exceed these target areas.
