Blend
compositing node
Blends frames from two sequences together using a simple linear blend.
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.
Parameters
Blend
|
Blend Method |
When a third input is not attached, a global blend is applied between the 2 inputs.
|
||||
|
Blend Factor |
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. |
||||
|
Normalize Weights |
If on, the weights will always be scaled to sum up to 1. |
||||
|
Blend Mask |
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. |
Merge
|
Overview |
These parameters specify how to build the output sequence when there are differences between the input sequences. |
|
Plane Merge |
If the planes in the inputs differ, this specifies what the output planes should be. |
|
Raster Depth |
If the raster depth for a given plane differs between inputs, this specifies when the output raster depth for the plane should be. |
|
Frame Range |
If the frame ranges of the inputs differ, this determines what the output range should be. |
|
Frame Rate |
If the frame rates of the inputs differ, this determines what the output frame rate should be. |
|
Frame Match |
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. |
