This operations blends frames from two sequences together using a simple linear blend. An optional third sequence can be used to specify the blend factor on a per-pixel basis.
When a third input is not attached, a global blend is applied between the 2 inputs.
Use Blend Factor
Out = (1-Blend) Input1 + Blend Input2
Use Blend Weights
Out = Weight1 Input1 + Weight2 Input2
Globally blends between input one (0) and two (1).
Input 1 Weight
If using blend weights, this specifies the factor to multiply input 1 by.
Input 2 Weight
This specifies the factor to multiply input 2 by.
If on, the weights will always be scaled to sum up to 1.
If a third input is used to control the blending, this menu selects the plane or component to use as the blend mask. Black is input 1, white is input 2.
Invert Blend Mask
If on, black is input 2, while white is input 1.
These parameters specify how to build the output sequence when there are differences between the input sequences.
If the planes in the inputs differ, this specifies what the output planes should be.
If the raster depth for a given plane differs between inputs, this specifies what the output raster depth for the plane should be.
If the frame ranges of the inputs differ, this determines what the output range should be.
If the frame rates of the inputs differ, this determines what the output frame rate should be.
If the frame rates of the inputs differ, this determines which input frame to pick when the cook time doesn’t reside on a frame boundary.

This example demonstrates a simple wipe effect using the Blend COP. The wipe transition is created by inputting an animated alpha mask into the Blend COP.
