Invert

AviSynth+
Up-to-date documentation: https://avisynthplus.readthedocs.io

Inverts one or several color channels of a clip.

Invert(clip clip [, string channels] )

clip  clip =

Source video.

string  channels = (all)

Defines which channels should be inverted by their initial letters, e.g. "R" (=red)

Any letters that don't correspond to a channel in the current colorspace are ignored.

Valid channel letters are:

R, G, B & A for RGB32 clips

R, G & B for RGB24 clips

Y, U & V for YUV clips

Letters are not case sensitive and may be given in any order.

By default, all channels of the current colorspace are inverted.

Example

AviSource("clip.avi")
ConvertToRGB32
Invert("BG")    # inverts the blue and green channels

AviSource("clip.avi")
ConvertToRGB24
Invert("A")     # no effect (no current A channel)
Invert("VUY")   # no effect (no current Y, U or V channels)
Invert("g, b")  # inverts the blue and green channels
