Blend
The Blend tool lets you blend two images by applying a blend factor. The
image connected to the A input is displayed when the Blend Factor is set to
0; the image connected to the B input is displayed when the Blend Factor is
set to 100. The Blend factor, like all parameters, can be animated, making it
easy to use this tool to create a blending transition between compositions.
To blend two images:
1 Drag the Blend tool from the Composition folder in the Tools tab to the
dependency graph in the Schematic view.
2 Connect the A and B images to the tool.
3 Set the Blend factor. If you set a value of 0, you see 100 percent of the
image connected to the A input. If you set a value of 100, you see one
hundred percent of the image connected to the B channel. In the
following example, the blend factor is set to 46 percent.
NOTE The Blend tool has a masking input and its attributes are also
animatablesee
