Video Equalizer¶

Description

This effect/filter sets brightness, contrast, saturation and approximate gamma adjustment.

Parameters

Parameter	Value	Description
Contrast	Float	Set the contrast expression. Negative values give a negative image. The value must be a float value in range -3.00 to 3.00. The default value is 1.00.
Brightness	Float	Set the brightness expression. The value must be a float value in range -1.00 to 1.00. The default value is 0.00.
Saturation	Float	Set the saturation expression. The value must be a float in range 0.00 to 5.00. The default value is 1.00.
Gamma	Float	Set the gamma expression. The value must be a float in range 0.00 to 3.00. The default value is 1.00.
Red / Green / Blue Gamma	Float	Set the gamma expression for red, green or blue. The value must be a float in range 0.00 to 3.00. The default value is 1.00.
Gamma Weight	Float	Set the gamma weight expression. It can be used to reduce the effect of a high gamma value on bright image areas, e.g. keep them from getting over amplified and just plain white. The value must be a float in range 0.00 to 1.00. A value of 0.0 turns the gamma correction all the way down while 1.00 leaves it at its full strength. Default is 1.00.
