Invert – After Effects Spotlight

The Invert effect inverts the color information of an image.

There are only two properties you can edit. The first is the Channel dropdown. This determines which channel or channels to invert. By default the effect inverts everything in the image. Black becomes white and so on. First let’s look at RGB, Red, Green and Blue. RGB inverts all three of the color channels together, but you can also invert an individual color channel if you want.

HLS stands for Hue, Lightness, and Saturation. HLS will invert all three, or you can invert them each separately.

YIQ inverts all three NTSC luminance and chrominance channels. Y stands for luminance, I stands for in-phase chrominance, and Q stands for quadrature chrominance.

Finally, Alpha will invert the alpha channel of an image. So, let’s say you had some keyed footage, you could invert the Alpha channel, and leave an outline of a person.

The Blend with Original property is basically just the transparency of the effect.

Much of this script was taken from the Adobe Help document on After Effects.
