Description

Inverts the values of the pixels. This function is equivalent to mt_lut("255 x -"), but faster.

Syntax and Parameters

mt_invert (clip, int "Y", int "U", int"V", string "chroma", int "offX", int "offY", int "w" int "h")


clip   =
Input clip.


int  Y = 3
int  U = 1
int  V = 1
These three values describe the actual processing mode that is to be used on each plane / channel. Here is how the modes are coded :
  • x = -255...0 : all the pixels of the plane will be set to -x.
  • x = 1 : the plane will not be processed. That means the content of the plane after the filter is pure garbage.
  • x = 2 : the plane of the first input clip will be copied.
  • x = 3 : the plane will be processed with the processing the filter is designed to do.


string  chroma = ""
When defined, the value contained in this string will overwrite the u & v processing modes.
This is a nice addition proposed by mg262 that makes the filter more user friendly. Allowed values for chroma are:
  • "process" : set u = v = 3.
  • "copy" or "copy first" : set u = v = 2.
  • "xxx", where xxx is a number : set u = v = -xxx.


int  offX = 0
int  offY = 0
"offX" and "offY" are the top left coordinates of the box where the actual processing shall occur. Everything outside that box will be garbage.


int  w = -1
int  h = -1
w and h are the width and height of the processed box. -1 means that the box extends to the lower right corner of the video. That also means that default settings are meant to process the whole picture.


Examples

mt_invert with default settings: 

AviSource("blah.avi")
mt_invert(Y=3, U=1, V=1, chroma="", w=-1, h=-1)
