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. |
