Working with the Safe Color Limiter Effect
In addition to the safe color warning system, you can also limit colors to safe ranges by applying
the Safe Color Limiter effect. The Safe Color Limiter effect modifies color and luminance values
in video material to bring the material within the safe color limits you define. If you use the Safe
Color Limiter effect, you do not have to make manual adjustments in the Color Correction tool to
ensure that video is within limits.
Understanding the Safe Color Limiter Effect
The Safe Color Limiter effect has effect parameters that control high and low color limits for
luminance, composite signal, and red, green, and blue color gamut. It also lets you change the
units for measuring these limits. These parameters parallel the options available in the Safe Color
settings.
When you first apply a Safe Color Limiter effect, its parameters default to the current limits in
the Safe Color settings. In the simplest situation, you can set limits in the Safe Color settings that
meet your needs (for example, luminance or composite signal standards set by a broadcaster),
and then apply the Safe Color Limiter effect to the video material you need to limit. Without any
further adjustment, the effect modifies the color and luminance values of any pixels in the video
material that exceed your limits, ensuring that the video meets the required standards. For more
information on safe color limit values and possible reasons for using them, see “Overview of
Safe Color Limits” on page 827.
When you want to make adjustments to the safe color limits that a Safe Color Limiter effect is
using, you do so using parameter controls in the Effect Editor. You can also view an analysis of
the image in the Source monitor that makes it easy to see exactly which pixel areas in an image
are outside the limits set for the effect. For more information, see “Using the Safe Color Limiter
Analysis Display” on page 840.
