Knoll Unmult: A Free Plug-in for After Effects CS6
If you are looking for a free and easy way to create alpha channels from images or videos shot on black backgrounds, you might want to check out Knoll Unmult, a free plug-in for After Effects CS6. Knoll Unmult was developed by John Knoll, one of the original creators of Photoshop, and it is available for download from Red Giant Software. In this article, we will explain what Knoll Unmult does, how to install it, and how to use it in your projects.
What is Knoll Unmult?
Knoll Unmult is a plug-in that generates an alpha channel from any image or video that has black pixels. This is useful for creating transparent backgrounds for flares, clouds, lightning, water droplets, or any other effects that are rendered on black. Knoll Unmult works by subtracting the black pixels from the image and creating a grayscale matte that can be used as an alpha channel. This way, you can easily composite your effects over any other footage without having to manually key out the black areas.
How to Install Knoll Unmult?
Knoll Unmult is compatible with After Effects CS3, CS4, and CS6 (64-bit). You can download it for free from Red Giant Software's website. To install it, simply unzip the downloaded file and place it in the following folder:
Mac: /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore/
Win: C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore\
Note that Knoll Unmult is not compatible with the newer versions of After Effects (CC and above), as they use a different plug-in architecture. However, you can still use Knoll Unmult in After Effects CC by using the Dynamic Link feature to import your compositions from After Effects CS6.
How to Use Knoll Unmult?
To use Knoll Unmult, simply apply it to any layer that has black pixels that you want to remove. You can find it under the Effect menu, in the Red Giant category. Once you apply it, you will see that the black pixels are replaced by transparency, and you can see through to the layers below. You can adjust the Threshold parameter to control how much black is removed from the image. A lower value will remove more black, while a higher value will preserve more details in the dark areas. You can also use the Invert option to reverse the effect and create a negative matte.
Here is an example of how Knoll Unmult can be used to create a realistic composite of a flare over a cityscape. First, we import a flare image that was rendered on black, and apply Knoll Unmult to it. Then, we import a cityscape image, and place it below the flare layer. We can adjust the blending mode, opacity, and color of the flare layer to match the lighting and mood of the scene. The result is a convincing composite that looks like the flare is actually shining over the city.
As you can see, Knoll Unmult is a simple but powerful tool that can help you create realistic composites with effects that are rendered on black backgrounds. It is also free and easy to install and use, so there is no reason not to give it a try.
