How to Make Retro 4:3 Webcam Borders in OBS Studio

This guide explains how to use the built-in “Color Source” feature in OBS Studio to design a stylized, retro-themed border for a 4:3 aspect ratio webcam feed. By leveraging OBS’s layering and scaling tools, you can create a clean, customized frame directly within the software without needing external graphic design programs.

Step 1: Set Your Webcam to a 4:3 Aspect Ratio

Before building the border, ensure your webcam feed is locked into a retro 4:3 aspect ratio.

1. Open OBS Studio and navigate to your Sources dock.
2. Double-click your webcam source (usually a Video Capture Device) to open its properties.
3. Change the Resolution/FPS Type from Device Default to Custom.
4. Set the Resolution to a standard 4:3 format, such as 1024x768, 800x600, or 640x480.
5. Click OK.

Step 2: Create the Color Source Layer

The Color Source will act as the physical border behind your webcam.

1. Click the + icon in the Sources dock and select Color Source.
2. Name the source (e.g., “Webcam Border Background”) and click OK.
3. In the properties window, click Select Color to choose a retro-themed color (such as neon pink, teal, or retro gray).
4. Set the Width and Height to be slightly larger than your webcam resolution to create the border frame. For example, if your webcam is 1024x768, set the Color Source to 1054x798 (this creates a 15-pixel border on all sides).
5. Click OK.

Step 3: Layer and Align the Sources

To make the border visible, you must arrange the layers correctly.

1. In the Sources dock, click and drag your Color Source so it sits directly underneath your webcam source.
2. Select your webcam source on the canvas, hold the Ctrl key (or Cmd on Mac), and select the Color Source as well.
3. Right-click the selection on the canvas, hover over Align, and select Center. Your webcam will now be perfectly centered over the color block, revealing an even border around the edges.

Step 4: Add a Multi-Layered Retro Effect (Optional)

To give the border a classic 80s or 90s aesthetic, you can stack multiple Color Sources to create a multi-tiered or drop-shadow effect.

• For a drop shadow: Duplicate your Color Source, change its color to black or dark purple, place it at the very bottom of the source stack, and use the arrow keys to offset it slightly to the bottom-right.
• For a double border: Create a second Color Source that is 10 pixels wider and taller than the first border, color it differently (e.g., yellow over magenta), and place it behind the first border.

Step 5: Group the Layers for Easy Moving

Once you are happy with the look of your retro border, group the sources so they do not lose alignment when you move them.

1. Select the webcam and all associated Color Sources in your Sources list.
2. Right-click the selected items and select Group Selected Items.
3. Name the group “4:3 Webcam and Border.”

You can now resize and reposition the entire group anywhere on your stream canvas without ruining the alignment of your custom border.
