How to Use Keylight 2.2 Plugin in Adobe After Effects

Keylight 2.2 is a powerful keying plugin that allows you to remove green or blue backgrounds from your footage in Adobe After Effects. It offers a range of settings and parameters to fine-tune your key and achieve realistic results. In this article, we will show you how to apply and use Keylight 2.2 in After Effects.

Step 1: Import Your Footage and Apply Keylight 2.2

First, you need to import your footage into After Effects and create a new composition. Then, go to the Effects & Presets panel and find Keylight 2.2 under the Keying subfolder. Drag and drop the effect onto your footage layer in the timeline.

Step 2: Select the Screen Color

Next, you need to select the color of the background that you want to remove. In the Effect Controls panel, use the Eyedropper tool in the Screen Color setting and click on the green or blue background in your footage. You should see the background disappear and a black and white matte appear instead.

Step 3: Adjust the Screen Matte Controls

Now, you need to refine your matte to remove any unwanted parts of the foreground or background. To do this, you can use the Screen Matte controls in Keylight 2.2. These controls allow you to adjust the black and white values of your matte and create a clean alpha channel.

The most important settings are Clip Black and Clip White. Clip Black sets the threshold for what is considered black (transparent) in your matte, while Clip White sets the threshold for what is considered white (opaque). You can use these sliders to eliminate any noise or spill in your matte.

To see your matte better, you can change the View setting from Final Result to Screen Matte. This will show you only the black and white matte without any color information. You can also use the Screen Softness setting to smooth out any jagged edges in your matte.

Step 4: Apply Key Cleaner and Advanced Spill Suppressor

After adjusting your matte, you can switch back to the Final Result view and see how your key looks. You may notice some artifacts or color spill on your foreground subject. To fix these issues, you can apply two additional effects: Key Cleaner and Advanced Spill Suppressor.

Key Cleaner is an effect that cleans up any remaining noise or edge problems in your key. It has a few settings that you can tweak, such as Reduce Chatter, Edge Radius, and Edge Thin. You can drag and drop this effect onto your footage layer after Keylight 2.2.

Advanced Spill Suppressor is an effect that removes any color spill from your foreground subject caused by the background color. It has two modes: Standard and Ultra. Standard mode is faster but less accurate, while Ultra mode is slower but more precise. You can drag and drop this effect onto your footage layer after Key Cleaner.

Step 5: Add a New Background

Finally, you can add a new background behind your keyed subject. You can use any image or video that you want as your background, as long as it matches the perspective and lighting of your foreground. You can import your background into After Effects and place it below your footage layer in the timeline.

You can also use some color correction or adjustment effects to blend your foreground and background better. For example, you can use Curves, Levels, or Hue/Saturation effects to match the color tone and contrast of your layers.

Conclusion

Keylight 2.2 is a versatile and powerful keying plugin that can help you create realistic composites in Adobe After Effects. By following these steps, you can easily remove green or blue backgrounds from your footage and replace them with new backgrounds of your choice.
