Inverts one or several color channels of a clip.

Syntax and Parameters

Invert (clip, string "channels")

clip

Source clip; all color formats supported.

channels

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 RGB(A) clips.

• Y, U, V, A for YUV(A) clips.

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

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

Default: "RGBA" if input clip is RGB, "YUVA" if input clip is YUV.

Examples

Invert the blue and green channels:

AviSource("clip.avi")
ConvertToRGB32()
Invert(channels="BG") # can also be written as channels="g, b"

Examples were Invert has no effect:

AviSource("clip.avi")
ConvertToRGB24()
Invert(channels="A")     # no effect (no current A channel)
Invert(channels="VUY")   # no effect (no current Y, U or V channels)
