Examples of Using Knoll Unmult

To demonstrate the power and versatility of Knoll Unmult, we will show you some examples of using it in different scenarios. You can follow along with these examples using your own footage or download some free stock footage from the links below.

Fire is one of the most common effects that can benefit from Knoll Unmult. Fire footage usually has a black background that needs to be removed to blend with the scene. Here are the steps to composite fire using Knoll Unmult:

• Import your fire footage and your background footage into After Effects and create a new composition.

• Drag the fire footage on top of the background footage in the timeline.

• Apply Knoll Unmult to the fire layer and adjust the Threshold parameter until you get a realistic transparency.

• Change the blending mode of the fire layer to Screen or Add to make it brighter and more vivid.

• Add some color correction, glow, or other effects to enhance the fire.
