DeLogo is a dedicated tool and video filter used to erase text, watermarks, and branding by blending the unwanted area with its surrounding pixels. Because “DeLogo” exists across multiple platforms, the exact usage method depends on whether you are using VSDC Free Video Editor, FFmpeg (command-line), or the classic VirtualDub plugin.
Here is how to use DeLogo across the three most common platforms. 1. Using DeLogo in VSDC Free Video Editor
VSDC offers a built-in DeLogo filter that allows you to quickly blur or pixelate a specific branding zone. Import Video: Open your video file inside the editor.
Add Filter: Go to the Video Effects tab, click Filters, and select DeLogo.
Position Mask: A rectangle will appear on your screen; drag and resize it directly over the branding or text.
Choose Preset: Open the Properties window on the right side of the interface.
Select Blur Style: Choose from presets like Pixelate, Box blur, Lens blur, Mosaic, or Gaussian blur.
Adjust Intensity: Use the Level slider to change the strength of the blur so it blends seamlessly. 2. Using the FFmpeg delogo Filter (Command Line)
If you prefer command-line tools, FFmpeg has a highly efficient delogo filter that uses interpolation to mask out a box using its outer border pixels.
Find Coordinates: Identify the exact top-left corner X and Y coordinates, alongside the Width (w) and Height (h) of the logo box.
Test Your Area: Run a test command with the show=1 option to see a green outline over the targeted text:
ffmpeg -i input.mp4 -vf “delogo=x=10:y=10:w=100:h=50:show=1” test_output.mp4 Use code with caution.
Keep Border Padding: Avoid starting the rectangle at coordinates 0,0. The filter requires at least a one-pixel buffer of surrounding context to sample from.
Process Final Video: Remove the show=1 parameter to render the final clean video:
ffmpeg -i input.mp4 -vf “delogo=x=10:y=10:w=100:h=50” final_output.mp4 Use code with caution.

For vintage video processing or frame-by-frame precision, the classic VirtualDub DeLogo plugin provides analytical masking. Load Video: Open your media file inside VirtualDub.
Open Filters: Navigate to the Video menu and click Filters, then choose Add and select DeLogo.
Create Analysis Mask: The plugin functions best if you feed it an “Analysis Frame”—a frame where you use a paint program to color the logo completely red.
Load the Mask: Click the Load… button next to Repair: Mask properties and select your painted image.
Fine-Tune Repair: Adjust the Power slider (to weigh the surrounding colors) and the Depth slider (to choose how many outer pixels are sampled).
Save Output: Close the filter options and export your clean video file.
