Channel Swap Filter

Rebuilds the picture by choosing what each colour channel (Red, Green, Blue, Alpha) should contain. Useful for fixing sources where the channel order is wrong, repurposing a black-and-white matte stored in one channel as the alpha for keying, creative colour effects (false-colour, channel swaps), inverting colours for negative looks, and inverting the alpha to flip a key inside-out.

Channel Swap Filter - Settings

Property	Description
`Set Red channel to:`	What the output Red channel is filled with — pick any source channel (Red, Green, Blue or Alpha) or a fixed value. Used to rearrange or replace the red component of the picture.
`Set Green channel to:`	What the output Green channel is filled with — pick any source channel or a fixed value. Used to rearrange or replace the green component of the picture.
`Set Blue channel to:`	What the output Blue channel is filled with — pick any source channel or a fixed value. Used to rearrange or replace the blue component of the picture.
`Set Alpha channel to:`	What the output Alpha channel is filled with — pick any source channel or a fixed value. A common use is to drive Alpha from a luminance matte stored in Red, Green or Blue so the source can be keyed.
`Invert RGB`	When on, inverts the colour channels (produces a photographic negative). Has no effect on the alpha channel.
`Invert Alpha`	When on, inverts the alpha channel — opaque areas become transparent and vice versa. Useful for flipping a key inside-out without creating a separate operator.
`Reset`	Reset all settings to their defaults (Red→Red, Green→Green, Blue→Blue, Alpha→Alpha, both inverts off).
