Channel effects

Arithmetic effect
The Arithmetic effect performs various simple mathematical operations on an image's red, green, and blue
channels.
The operation to perform between the value you specify for each channel and the existing value of that
Operator
channel for each pixel in the image:
• Apply bitwise logical operations.
And, Or, and Xor
•
Add, Subtract, Multiply, and Difference
• Set the pixel's channel value to the greater of the specified value and the pixel's original value.
Max
•
Set the pixel's channel value to the lesser of the specified value and the pixel's original value.
Min
•
Set the pixel's channel value to 0 if the pixel's original value is greater than the value specified;
Block Above
otherwise, leave the original value.
•
Set the pixel's channel value to 0 if the pixel's original value is less than the value specified; otherwise,
Block Below
leave the original value.
•
Set the pixel's channel value to 1.0 if the pixel's original value is above the specified value; otherwise, set the
Slice
value to 0. In both cases, the values for the other color channels are set to 1.0.
Prevents all functions from creating color values that exceed the valid range. If this option isn't
Clip Result Values
selected, some color values may wrap around.
Blend effect
The Blend effect blends two clips using one of five modes. After you blend clips using this effect, disable the clip you
selected from the Blend With Layer menu by selecting the clip and choosing Clip > Enable.
The clip to blend with (the secondary or control layer).
Blend With Layer
Blending mode:
Mode
• Color Only colorizes each pixel in the original image based on the color of each corresponding pixel in the
secondary image.
•
Tint Only is similar to Color Only but tints pixels in the original image only if they are already colored.
•
Darken Only darkens each pixel in the original image that is lighter than the corresponding pixel in the secondary
image.
• Lighten Only lightens each pixel in the original image that is darker than the corresponding pixel in the
secondary image.
•
Crossfade fades the original image out while the secondary image fades in.
The effect's transparency. The result of the effect is blended with the original image, with the
Blend With Original
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.
Specifies how to position the control layer.
If Layer Sizes Differ
