selected from the Blend with Layer menu by selecting the clip and choosing Clip > Enable.

Adjust the following controls for the Calculations effect:
Input Channel Specifies the channel to extract and blend with the original clip:
• RGBA Displays all channels normally.
• Gray Shows the luminance of the original RGBA image.
• Red/Green/Blue/Alpha Converts all channels to the value of the specified channel.
Invert Input Inverts the clip before the effect extracts the specified channel information.
Second Layer Specifies the video track with which Calculations blends the original clip.
Second Layer Channel Specifies the channel to be blended with the input channels.

lates the blend.
Stretch Second Layer To Fit Stretches the Second Layer’s edges to the original layer’s edges before blending. If you
don’t select this control, the Calculations effect centers the second source layer in the original layer and crops it to fit
the effect layer’s boundaries.
