System information
4. The waveform monitor displays the luma values of the video signal:
Frame Waveform Description
The dark left half of the frame is displayed on the left of
the waveform, and the light right half is displayed on the
right.
Most luma values are concentrated toward the top of the
monitor, with some values exceeding the recommended
peak of 110.
The resulting image appears washed out.
Most luma values are concentrated toward the bottom of
the monitor.
The resulting image appears too dark.
Luma values are evenly distributed in the monitor.
The resulting image appears more balanced.
5. Hover over a portion of the monitor to display the luma value at the pointer position:
The Histogram Monitor
The histogram monitor in the Video Scopes window allows you to monitor color levels and contrast of your
video. Use the histogram before rendering your project to find and correct out-of-range values that could
cause problems on the destination playback device.
The bar graph plots the number of pixels that exist for each color intensity. For example, when using the
Blue setting, the vertical axis represents the number of pixels, and the horizontal axis represents the RGB
color range from 0,0,0 to 0,0,255.
To get acquainted with the histogram, use an external monitor to preview your video and watch the
video output and histogram as you use plug-ins to modify the colors.
For more information, see "Using an External Video Monitor" on page 474.
