Apply 3D LUT to Logitech Webcam in OBS Studio

Color grading your webcam feed can drastically improve your live stream’s visual quality. This guide provides a direct, step-by-step walkthrough on how to apply a 3D Lookup Table (LUT) to your Logitech webcam within OBS Studio, allowing you to achieve a professional, cinematic look with ease.

Step 1: Prepare Your LUT File

Before starting, ensure you have a compatible LUT file saved on your computer. OBS Studio natively supports both .cube files (the industry standard for 3D LUTs) and specific PNG-based LUT strips.

Step 2: Add Your Logitech Webcam to OBS Studio

  1. Open OBS Studio.
  2. Locate the Sources dock at the bottom of the screen.
  3. Click the + (Add) icon and select Video Capture Device.
  4. Name your source (e.g., “Logitech Webcam”) and click OK.
  5. In the properties window, select your Logitech camera from the Device dropdown menu, configure your preferred resolution and frame rate, then click OK.

Step 3: Open the Filters Menu

  1. Right-click on your Logitech webcam source in the Sources list (or right-click the webcam feed directly in the preview window).
  2. Select Filters from the context menu. This will open a new configuration window.

Step 4: Add the Apply LUT Filter

  1. In the Filters window, locate the Effect Filters section in the bottom-left corner.
  2. Click the + (Add) icon at the bottom of this section.
  3. Select Apply LUT from the list of available effects.
  4. Give the filter a name if prompted, then click OK.

Step 5: Locate and Load Your LUT

  1. In the filter properties on the right side of the window, look for the Path field.
  2. Click the Browse button.
  3. Navigate to the folder on your computer where your .cube or PNG LUT file is stored.
  4. Select the file and click Open.

Step 6: Adjust the LUT Intensity

  1. Locate the Amount slider directly below the file path.
  2. Drag the slider to adjust the intensity of the color grade. A value of 1.00 applies the LUT at 100% strength, while lower values blend the LUT with your webcam’s original colors.
  3. Once you are satisfied with the color grading, click Close at the bottom-right of the Filters window.
