[edit] Description

A script to reduce chromatic aberration. This function stretches the red, green and/or blue channel according to a given factor symmetrically around the center of the frame and crops it afterwards. Note that chromatic aberration also smears the image a bit, which is not compensated by this function.

[edit] Syntax and Parameters

FixChromaticAberration (clip clip, val "red", val "green", val "blue", val "x", val "y")

clip   =
Input clip.

val  red = 1
val  green = 1
val  blue = 1
red, green and blue are stretching (resizing) factors against the original clip size. Factors of e.g. red=1.015, green=1.01 allow to compensate the colored edges near the corners of the image which appear from lenses with 'chromatic aberration'.

val  x =
val  y =
x and y allow to set the center of the aberration circle. It defaults to the center of the image.

[edit] Examples

FixChromaticAberration with default settings:

FixChromaticAberration(red=1, green=1, blue=1)
