Solid Composite

Solid Composite allows you to blend a solid color with your layer. You have the various blending modes available, and options regarding the opacity of the source layer (the original image), the color of the solid, the blending mode, and the opacity of the solid. This works well for anyone looking to add a color…

Shift Channels

Shift Channels does the exact same thing as set channels except with less control. With set channels you can choose any layer(Including the current layer) to get your values from to switch the information in the image. With Shift Channels, you can only use the channels from the layer itself. So there is not much…

Set Matte

The Set Matte effect replaces the alpha channel (matte) of a layer with a channel from another layer above it for the creation of traveling matte results. The Set Matte effect is intended only to provide compatibility with projects created in earlier versions of After Effects that use the Set Matte effect. Sometimes, it’s easier…

Set Channels

Set Channels allows one layer’s channels to be overlaid onto the source’s. It copies channels from control layers (source layers) to the red, green, blue, and alpha channels of the effect layer. For example, you can take the luminance values of the pixels of a control layer and use them as the blue values for…

Remove Color Matte

The Remove Color Matting effect removes color fringes (halos) from layers with premultiplied color channels. Halos often occur when an area of partial transparency retains the color of the original background and is composited into a context with a different background color. Use this effect in conjunction with effects that create transparency—such as keying effects—to…

Minimax

The Minimax effect assigns each channel of a pixel the minimum or maximum value for that channel found within a specified radius. This effect can be used to enlarge or reduce a matte. For example, a white solid area surrounded by black shrinks one pixel on each side using Minimum and a radius of 1….

Invert

The invert effect is pretty self-explanatory, it inverts the values given. What makes this effect powerful though is that you can choose what channel to invert in your image. Channel: Which channel or channels to invert. Each group of items operates in a particular color space, inverting either the entire image in that color space…

Compound Arithmetic

The Compound Arithmetic effect mathematically combines the layer to which it is applied with a control layer. The Compound Arithmetic effect is intended only to provide compatibility with projects created in earlier versions of After Effects that use the Compound Arithmetic effect. Using blending modes is usually more effective than using the Compound Arithmetic effect….

Channel Combiner

The Channel Combiner effect extracts, displays, and adjusts channel values for a layer. This effect is one of the most interesting effects and it is hard to fully understand what it does. Channel Combiner offers several distinctly different useful functions. One, it’s a great Channel shifter. You can move information between Color and Luminance channels. It’s…

CC Composite

Composite is meant to be used in conjunction with other effects applied before Composite. To use Composite, apply an effect/effects to the layer, apply Composite and select composite method. Controls Opacity: Use this control to determine the transparency of the original source layer in the composite. Composite Original: Use this pop-up menu to select which…

Calculations

The Calculations effect combines channels of one layer with the channels of a second layer. Input Channel: The channel to extract and use as input to the blending operation. RGBA displays all channels normally. Gray converts all color channel values for a pixel to the luminance value of the original pixel. Red, Green, or Blue…

Blend

The Blend effect blends two layers using one of five modes. You can blend layers more easily and quickly using blending modes, but you can’t animate blending modes. The advantage of using the Blend effect is that you can animate it. (See Blending modes and layer styles.)   John Dickinson explains the use of the…
