Broadcast Monitor ยท Picture & Scopes

See why the picture looks the way it does.

Start with exposure and color. Each tool answers a different question, and you can learn one at a time.

Start with the picture: false color and zebras.

False color: make brightness visible

False color replaces the image's normal colors with colors that represent brightness ranges. Instead of trying to judge a face against a bright background, look at the range that face falls into.

Try it during rehearsal: frame your presenter, turn on false color, and observe how the face changes as you adjust exposure. Use the display's scale and your intended look; there is no single exposure value that suits every face or lighting design.

False color is included in all three editions.

Zebras: flag areas that need attention

Zebras place a striped overlay on parts of the image that meet a brightness condition. They make it easy to locate those areas without looking away from the picture.

Try it on a bright stage: use high zebras to see which parts of a white shirt or projection screen cross your selected threshold. A zebra warning invites a closer look; it does not automatically mean the image is clipped.

Free includes high zebras. Express and Professional include all zebra options.

Built-in concert scene in false color, showing brightness ranges across performers, spotlights, and audience
False color separates bright spotlights, performers, and the dark audience into brightness ranges. Compare the normal picture to connect each reading to its subject.

The same built-in scene in normal color. Switch between the ordinary picture and false color to learn how lighting and exposure appear in the measurements.

Focus assistance: make fine edges easier to see.

Detail enhancement boosts fine edges in the RGB picture view, with optional grayscale. Adjust its strength to make detail easier to judge, and use the threshold to limit enhancement of low-level noise. Express and Professional include these controls.

During camera setup: maximize the picture pane, enable detail enhancement, and watch fine edges as you adjust focus. Turn it off again to judge the ordinary picture. Enhancement helps reveal detail; it cannot restore detail that the camera did not capture.

Your measurements stay on the source

This is a viewing aid. It does not modify the captured samples or the signal measured by the waveform, vectorscope, or histogram. Zebra thresholds still use source measurements.

If you send a composed monitoring layout to an output, its picture pane includes the enhancement. Disable it when you want that output to show the ordinary picture.

Waveform: where is the brightness?

A waveform plots signal level vertically and image position horizontally. Bright parts appear higher on the display; dark parts appear lower. That relationship helps you connect a reading to an area of the picture.

During a live event: check whether a spotlight is pushing a presenter's face much higher than the rest of the scene, or compare black and highlight levels as you move between cameras. Look for lost separation at the extremes, then check the picture as you adjust.

Express includes Y brightness views and parades. Professional adds the full waveform mode selection.

What is a parade?

A parade separates signal components into displays side by side. An RGB parade, for example, lets you compare the red, green, and blue channels.

On a subject that should be neutral, a channel that sits noticeably higher than the others can help explain a color cast. Use a known neutral subject when matching balance: a red backdrop should have more red, so unequal channels across an entire scene are not automatically a problem.

Production payoff: a more informed starting point for camera matching, especially when cuts reveal brightness or color differences.

YRGB waveform parade with separate brightness, red, green, and blue traces
Read brightness and the three color channels side by side. This concert scene has deliberately colored lighting; compare a known neutral subject when judging color balance.

Vectorscope: what is the color doing?

A vectorscope shows color as direction and distance from the center. Direction represents hue; distance represents saturation, or how strong the color is. Neutral content stays near the center.

During camera matching: compare the same subject under the same lighting. Does one camera push color in a different direction? Is its color much stronger? The vectorscope helps make those differences visible.

Included in Express and Professional.

Histogram: how is brightness distributed?

A histogram groups pixels by level. It shows how much of the image falls into dark, middle, and bright ranges, giving you a quick overview of the signal's distribution.

During setup: watch how the distribution changes when the stage lights come up. A concentration at one edge is worth investigating, but it may simply reflect the scene. Unlike a waveform, a histogram does not tell you where those pixels are in the image.

Express includes Y and parade histograms. Professional includes all histogram modes.

Vectorscope of the concert scene showing blue and magenta stage-light color
The stage lighting extends the trace toward blue and magenta. Direction shows hue; distance from the center shows saturation. Open the larger view to inspect the trace and reference targets.
Brightness histogram of the concert scene displayed with a logarithmic count scale
Read dark levels on the left and bright levels on the right. This scene contains a large dark audience and small bright spotlights. A logarithmic count scale keeps the less common levels visible.

These examples use a built-in sample scene. Explore sample scenes and test patterns without capture hardware, then apply what you learn to your production signal. The guide identifies which editions include each monitoring tool.
