ShortGenerator

A Python-based tool for automatically generating short-form videos from longer video content, optimized for platforms like TikTok, Instagram Reels, and YouTube Shorts.

Features

  • Automatic loud moment detection: Identifies exciting parts of videos using audio analysis
  • AI-powered transcription: Uses Whisper for accurate speech-to-text conversion
  • Dynamic subtitles: Creates engaging, word-by-word highlighted subtitles in the style of popular content creators
  • Vertical format optimization: Automatically converts landscape videos to 9:16 aspect ratio
  • Batch processing: Generate multiple shorts from a single video

Requirements

  • Python 3.8+
  • FFmpeg
  • Required Python packages (install with pip install -r requirements.txt):
    • moviepy
    • faster-whisper
    • numpy

Installation

  1. Clone the repository:
git clone https://git.ptbox.org/klop51/ShortGenerator.git
cd ShortGenerator
  1. Install dependencies:

Usage

Basic usage:

python shorts_generator2.py your_video.mp4
