System information
Monitoring Video with Scopes
From the View menu, choose Video Scopes to toggle the display of the Video Scopes window.
Broadcast video uses a narrower range of color than the RGB you see on your computer. When you
broadcast a project that contains out-of-gamut (out-of-range) colors, you can introduce image problems
or even noise into the audio stream.
Use the scopes to analyze your video and adjust accordingly with the Brightness and Contrast, Broadcast
Colors, Color Corrector, Color Corrector (Secondary), and Levels plug-ins before rendering.
Choose a setting from the drop-down list to choose which scope you want to display.
You can use split-screen previews to help match colors between clips. When the split-screen preview
mode is set to Clipboard, the Video Preview and Video Scopes windows will display the frame you
copied to the clipboard and the current frame. For more information, see "Split-Screen Previews" on
page 472.
When you're working with a stereoscopic 3D project, video scopes measure the right-eye video unless
your stereoscopic 3D mode for preview is set to Left Only. For more information, see "Setting up your
stereoscopic 3D project" on page 201.
The Vectorscope Monitor
The vectorscope monitor in the Video Scopes window allows you to monitor the chroma values (color
content) of your video signal. The monitor plots hue and saturation on a color wheel.
The vectorscope displays targets for broadcast-legal saturations of red (R), magenta (Mg), blue (B), cyan
(Cy), green (G), and yellow (Yl). Individual colors in your video signal are displayed as dots in the
vectorscope. A dot's distance from the center of the scope represents its saturation, and the angle of the line
from the dot to the center of the scope represents its hue.
For example, if an image has a blue cast, the distribution of dots in the vectorscope will be concentrated
toward the blue portion of the color wheel. If the image includes out-of-range blue values, the vectorscope
display will extend beyond the blue target.
You can use the vectorscope to calibrate color between scenes. Without calibration, you may see noticeable
color differences between scenes from multicamera shoots.
1. From the View menu, choose Video Scopes to toggle the display of the Video Scopes window.
2. Choose Vectorscope from the drop-down list.
3. Position the cursor in the frame you want to analyze. If the Update Scopes While Playing button
is selected, you can monitor your video during playback.
