This effect/filter applies the Kirsch operator to the input video stream. It detects edges (non-linear edge detector) and, in the default settings, colors them in yellowish green, and colors are somewhat posterized. Compare Prewitt, Roberts and Sobel effects.
The effect has keyframes.
Planes - Set which planes will be processed, unprocessed planes will be copied. Default is Y.
Scale - Set value which will be multiplied with filtered result
Delta - Set value which will be added to filtered result
