This Python script provides a simple way to overlay two logo images onto a video. It is especially useful for adding logos or watermarks to videos for branding or identification purposes.

Before you can use this tool, make sure you have the following installed:

• Python 3.x
• OpenCV (cv2) library
• argparse library (usually included in Python standard library)

You can install OpenCV using pip:

pip install opencv-python-headless imageio imageio[ffmpeg] -i https://pypi.org/simple 

To overlay logos on a video, run the script overlay_logos.py with the following command:

python overlay_logos.py --background <path_to_video> --left-logo <path_to_left_logo> --right-logo <path_to_right_logo> --output <output_video_path> --scale_factor <scale_factor>

• <path_to_video>: The path to the input video file.
• path_to_left_logo>: The path to the first logo image file.
• <path_to_right_logo>: The path to the second logo image file.
• <output_video_path>: The path to save the output video file.
• <scale_factor> (optional): Scaling factor for logos (default: 4).

Here's an example of how to use the script:

python overlay_logos.py --background resources/background.mp4 --left-logo resources/zkverse.png --right-logo resources/partners/tensor.png --output output/zktensor.mp4 --scale_factor 6

This command will overlay zkverse.png on the left side of each frame and tensor.png on the right side of each frame in the background.mp4, and save the resulting video as zktensor.mp4. The scale factor for the logos is set to 6.

For a practical demonstration of how to use the Video Logo Overlay Tool, refer to the example.py file included in this package. This file contains a sample script that illustrates the basic usage of the tool with predefined paths and parameters.

To run the example, navigate to the directory containing example.py and execute the following command in your terminal:

python example.py

The example.py script is pre-configured with sample paths for the background video, left and right logos, and the output video path. It also sets an example scale factor for the logos. Running this script will produce an output video demonstrating the overlay capabilities of the tool.

./resources
│   background.mp4
│   zkverse.png
└───partners
        madlads.jpg
        tensor.png

This structure is helpful for users to understand the expected directory setup for the script.

You can modify the example.py file to test different videos, logos, and scale factors. This is an excellent way to familiarize yourself with the tool's functionality and to see firsthand how various inputs affect the final output.

Supports overlaying two logo images on a video. Resizes the logos to fit the video frame while maintaining aspect ratio. Customizable scaling factor for logos. Output video is saved in the mp4 format.

The script includes error handling to check for missing or invalid file paths and provides informative error messages.
