• numpy
• argparse
• os
• pytube
• re
• random
• datetime

Usage

python script_name.py [OPTIONS] INPUT

Arguments:

    --output: Path to save the stroboscopic image. Default: stroboscopic_image.jpg in the current directory.
    --add_datetime_postfix: Option to postfix the output filename with the current date and time.
    --threshold: Difference detection threshold. Default: 50.
    --blend_ratio: Blend ratio between averaged changes and base frame. Default: 1.0.
    --duration_range: Specify the start and end times in seconds to process. For example, use 10,20 for the 10th to 20th second.
    --random_range: Duration in seconds to randomly select within the specified or full video duration.
    --blur_size: Gaussian blur kernel size (must be odd). Default: 5.
    --open_kernel_size: Size of the structuring element for morphological operations. Default: 5.
    --frame_interval: Interval for sampling frames from the video (default: 1 to process every frame).

Example:

To generate a stroboscopic image from a local video:

bash

python strobe.py my_video.mp4

To generate a stroboscopic image from a YouTube video:
