Video Processing Tool

In this Python tool processes a video file by extracting short clips, applying filters and effects, and generating subtitles for each clip. The processed clips are saved as new video files along with corresponding subtitle files.

Features

• Extracts clips of a specified duration from the input video.
• Applies image processing effects including brightness, contrast, saturation adjustments, and blurring.
• Generates simple subtitle files for each clip.

Requirements

To run this script, you'll need the following Python packages:

• opencv-python
• pysrt

You can install these using pip:

pip install opencv-python pysrt

Usage

1. Input Video: The script prompts you to enter the link to a YouTube video. Make sure to use a video URL that is accessible and can be downloaded.

2. Clip Duration: The default duration for each extracted clip is set to 10 seconds. You can modify this value in the script as needed.

3. Run the Script: Execute the script using Python:

   python video_processor.py

4. Output:

   • The processed clips will be saved as clip0_out.mp4, clip1_out.mp4, etc.
   • Corresponding subtitle files will be saved as clip0_subtitle.srt, clip1_subtitle.srt, etc.

Code Explanation

• Video Capture: The script uses OpenCV to read frames from the video.

• Image Processing: Each frame within the clip duration is processed using filters and effects:

  • Brightness and Contrast: Adjusts the brightness and contrast of the frame.
  • Saturation: Modifies the saturation of the frame.
  • Blurring: Applies Gaussian blur and combines with a weighted blend for a smoother look.

• Subtitle Generation: For each clip, a simple subtitle text ("This is a sample subtitle") is generated and saved in a .srt file format.

Limitations

• The script assumes the video file can be read directly via OpenCV, which may not be applicable for all YouTube links without prior downloading.
• Subtitle text is static; you may want to customize it based on the content of each clip.
