As a video editor, you’ve likely encountered situations where you need to remove unwanted objects or elements from your footage. Perhaps you’re working on a green screen project, and the talent’s clothes blended in with the background, or maybe you’re trying to erase a distracting object from the scene. That’s where a garbage matte comes in – a powerful tool in Premiere Pro that helps you isolate and eliminate unwanted parts of your footage. In this article, we’ll delve into the world of garbage mattes, exploring what they are, why you need them, and, most importantly, how to create one in Premiere Pro.
What is a Garbage Matte?
A garbage matte is a type of mask used in video editing to remove unwanted objects or areas from your footage. The term “garbage” refers to the unwanted elements you’re trying to eliminate, while “matte” refers to the process of creating a mask or outline around the object. Think of it like a digital eraser that helps you remove distractions and focus attention on the main subject.
Garbage mattes are particularly useful when working with green screen or chroma key footage, where the goal is to separate the subject from the background. By creating a garbage matte, you can isolate the subject and remove any unwanted spill or contamination from the background.
Why Do You Need a Garbage Matte?
There are several scenarios where a garbage matte is essential:
1. Green Screen and Chroma Keying
When shooting green screen footage, it’s not uncommon for the talent’s clothes or accessories to blend in with the background. A garbage matte helps you separate the subject from the background, ensuring a clean and professional-looking key.
2. Object Removal
Perhaps you’re working on a project that requires removing a distracting object from the scene, such as a microphone boom or a pesky bystander. A garbage matte allows you to isolate and eliminate the object, creating a more polished final product.
3. Advanced Compositing
Garbage mattes are also useful when combining multiple elements in a composite shot. By creating a matte around each element, you can control the opacity, color, and other attributes of each layer, resulting in a more realistic and convincing final product.
Creating a Garbage Matte in Premiere Pro
Now that we’ve covered the what and why of garbage mattes, let’s dive into the how. Creating a garbage matte in Premiere Pro involves several steps, but don’t worry – we’ll break it down into manageable chunks.
Step 1: Prepare Your Footage
Before you start creating your garbage matte, make sure your footage is properly organized and labeled in Premiere Pro. This will save you time and frustration down the line. Create a new project, import your footage, and add it to a sequence.
Step 2: Identify the Unwanted Object
Watch your footage and identify the object or area you want to remove. This could be a person, an object, or even a specific color. Take note of the object’s shape, size, and movement, as this will affect how you create your garbage matte.
Step 3: Create a New Layer
Create a new layer in your Premiere Pro timeline by going to Layer > New > Solid. Name this layer “Garbage Matte” or something descriptive. This layer will serve as the foundation for your garbage matte.
Step 4: Draw the Garbage Matte
With your new layer created, it’s time to draw the garbage matte. Premiere Pro offers several tools for drawing mattes, including the Pen tool, the Brush tool, and the Vector tool. For this example, we’ll use the Pen tool.
Select the Pen tool and click on the layer panel to draw the matte. Start by creating a rough outline around the unwanted object. Don’t worry too much about precision at this stage – we’ll refine the matte later.
Step 5: Refine the Garbage Matte
Once you have a rough outline, refine the matte by adjusting the control points and Bezier handles. You can also use the Alt key to toggle between the Pen tool and the Delete Anchor Point tool, allowing you to remove unnecessary points and fine-tune the matte.
Step 6: Feather the Garbage Matte
To create a more natural-looking matte, feather the edges by going to the Effect Controls panel and adjusting the Feather settings. This will help soften the edges of the matte and reduce any harsh lines.
Step 7: Invert the Garbage Matte
To invert the garbage matte, go to the Effect Controls panel and click on the Invert checkbox. This will reverse the matte, allowing you to remove the unwanted object from your footage.
Step 8: Apply the Garbage Matte
Finally, apply the garbage matte to your original footage by dragging the “Garbage Matte” layer below your original footage layer in the timeline. Go to the Effect Controls panel and adjust the Matte settings to fine-tune the effect.

Tips and Variations
While the above steps provide a solid foundation for creating a garbage matte, there are several variations and techniques you can use to refine your results:
1. Using Multiple Mattes
In some cases, you may need to create multiple mattes to remove multiple objects or areas from your footage. Simply create a new layer for each matte and follow the same process.
2. Animating the Garbage Matte
If the unwanted object is moving in your footage, you may need to animate the garbage matte to follow its movement. Use the Pen tool to create keyframes and adjust the matte over time.
3. Using Third-Party Plugins
Premiere Pro offers a range of third-party plugins that can help streamline the garbage matte process. Consider using plugins like Mocha or -trackX to simplify the process and achieve more accurate results.
Conclusion
Creating a garbage matte in Premiere Pro is a powerful technique for removing unwanted objects and areas from your footage. By following the steps outlined above, you can create a professional-looking matte that helps you achieve a more polished final product. Remember to refine your matte, feather the edges, and invert the effect to achieve a seamless integration with your original footage.
With practice and patience, you’ll be creating garbage mattes like a pro, taking your video editing skills to the next level and delivering stunning results that will leave your clients and audience in awe.
