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