Blend With Original The effect’s transparency. The result of the effect is blended with the original image, with the effect result composited on top.
The higher you set this value, the less the effect affects the clip. For example, if you set this value to 100%, the effect has no visible result on the
clip. If you set this value to 0%, the original image does not show through.

If Layer Sizes Differ Specifies how to position the control layer.

Calculations effect

The Calculations effect combines the channels of one clip with the channels of another clip.

Original images (left and center), and with effect applied (right)

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 converts all color channel values for a pixel to the value
of the selected color channel for the original pixel. Alpha converts all channels to the value of the alpha channel for the original pixel.

For instructions on using the Calculations effect and the Ramp effect, see

Schell.

Invert Input Inverts the clip before the effect extracts the specified channel information.

Second Layer The video track with which Calculations blends the original clip.

Second Layer Channel The channel to be blended with the input channels.

Second Layer Opacity The opacity of the second video track. Set to 0% for the second video track to have no influence on the output.

Invert Second Layer Inverts the second video track before the effect extracts the specified channel information.

Stretch Second Layer To Fit Stretches the second video track to the dimensions of the original clip before blending. Deselect this option to
center the second video track on the original clip.

Preserve Transparency Ensures that the original layer’s alpha channel isn’t modified.

Compound Arithmetic effect

The Compound Arithmetic effect mathematically combines the clip to which it’s 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.

Second Source Layer Specifies the video track to use with the current clip in the given operation.

Operator Specifies the operation to perform between the two clips.

Operate On Channels Specifies the channels to which the effect is applied.

Overflow Behavior Specifies how pixel values that exceed the allowed range are treated:

Clip Indicates that the values are limited to the allowed range.

Wrap Indicates that values exceeding the allowed range wrap around from full on to full off, or from full off to full on.

Scale Indicates that the maximum and minimum values are calculated and the results are stretched down from that full range to the range
of allowable values.

Stretch Second Source To Fit Scales the second clip to match the size (width and height) of the current clip. If this option is deselected, the
second clip is placed at its source’s current size, aligned with the upper left corner of the source clip.

Blend With Original The effect’s transparency. The result of the effect is blended with the original image, with the effect result composited on top.
The higher you set this value, the less the effect affects the clip. For example, if you set this value to 100%, the effect has no visible result on the
clip. If you set this value to 0%, the original image does not show through.

Invert (video) effect

The Invert (video) effect inverts the color information of an 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 or just a single channel.

RGB/Red/Green/Blue RGB inverts all three of the additive color channels. Red, Green, and Blue each invert an individual color channel.

HLS/Hue/Lightness/Saturation HLS inverts all three of the calculated color channels. Hue, Lightness, and Saturation each invert an
individual color channel.

YIQ/Luminance/In Phase Chrominance/Quadrature Chrominance YIQ inverts all three NTSC luminance and chrominance channels. Y
(luminance), I (in-phase chrominance), and Q (quadrature chrominance) each invert an individual channel.

Alpha Inverts the alpha channel of the image. The alpha channel isn’t a color channel; it specifies transparency.

Blend With Original The effect’s transparency. The result of the effect is blended with the original image, with the effect result composited on top.
The higher you set this value, the less the effect affects the clip. For example, if you set this value to 100%, the effect has no visible result on the
clip; if you set this value to 0%, the original image doesn’t show through.
