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 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.
