The Video Scopes Window
Choose View | Window | Video Scopes to toggle the display of the Video Scopes window in VEGAS® Pro.
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.
