Lyric Gradient Map
The Lyric Gradient Map filter is a stylizing effect similar to the Gradient Map tool in Photoshop. It takes a linear gradient of up to 5 color bands and maps the luminance levels in the source video image to colors across the gradient, dark pixels to the left side of the gradient running up through light tones to the right side. The gradient can be displayed in place of the mapped image for reference purposes or to enable the filter to be a used as a simple color gradient generator.
The Lyric Gradient Map filter includes a set of effect controls that are common across all Lyric effect filters. For a detailed description of these controls, please see the Common Effect Controls documentation.
Additionally, all Lyric Effect filters can be applied through mattes or masks to constrain the filter effect to particular areas of the image. For background information on mattes and masks, please refer to the Lyric Matte Primer.
The Gradient Colors slider sets how many color bands are in the gradient. Note that it is a slider and so can be animated to change color band counts dynamically. The Color Ramp dropdown menu lets you choose between linear or smooth color ramps between the band colors.
The color and position of each of 5 possible bands is set in the following color and color position controls. The Color controls can be expanded in place to allow interactive HSB setting of colors, or the swatches can be clicked to open up the Apple color picker for more options. The Color Position sliders set the position of each color band within the gradient, with 0 being to the far left (and so mapping to the blacks in the source image), and 255 being on the far right (and so mapping to the whites in the source image).
For example, the gradient used in the top left example above is shown below. Working across the gradient, the dark-shadows of the source image map to blacks, mid-shadows to the blue, mid-tones to yellow/red, mid-highs to red and highs to yellow again, as can be seen in the example.
Turning on the Show Gradient checkbox outputs the gradient instead of the mapped source image.
The Effect Controls section is a set of common controls that are documented on the Common Effect Controls page. They can be used to achieve masked and other specialized filter effects.
