🔧 Installation

1. Clone the repository:

   git clone https://github.com/yourusername/python-ai-video-gen.git
   cd python-ai-video-gen

2. Install dependencies:

   pip install -r requirements.txt

3. Set up your environment variables by creating a .env file:

   GOOGLE_API_KEY=your_gemini_api_key_here
   

4. Prepare the assets folders (optional - will be created automatically if they don't exist):

   mkdir -p assets/videos assets/music assets/fonts output temp

5. Start the application:

   python app.py

6. Open your browser and navigate to:

   http://localhost:5000
   

📝 Usage

Web Interface

1. Create Videos: Enter your custom quote or generate one with AI
2. Upload Assets: Add your background videos, music, and custom fonts
3. Manage Files: Browse and preview your uploaded assets
4. Download Videos: Access your generated videos from the "Output" tab

Python Module

You can also use the video creator as a standalone Python module:

import video_creator

# Generate a video with a custom quote
quote = "Dream big, work hard, stay focused."
author = "Unknown"
output_path = video_creator.create_video(quote, author)
print(f"Video created at: {output_path}")

# Or generate a video with an AI-created quote
quote, author = video_creator.generate_quote()
output_path = video_creator.create_video(quote, author)

🎨 Customization

Video Settings

The video generator creates 15-second clips optimized for vertical video platforms. You can modify settings in video_creator.py:

• TARGET_DURATION: Change the video length (default: 15 seconds)
• Resolution: Adjust dimensions (default: 1080×1920)
• Font Styles: Custom text rendering options

Web Interface

The web interface uses a modern glassmorphism design. Customize colors and styles in static/css/style.css.

🤖 How It Works

1. Quote Generation:

   • Uses Google's Gemini 1.5 Pro AI to create original inspirational quotes
   • Falls back to a curated list of quotes if API is unavailable

2. Text-to-Speech:

   • Converts the quote to natural-sounding speech using gTTS

3. Video Processing:

   • Takes background videos and crops them to vertical format
   • Applies text overlay with stylized typography
   • Adds background music and syncs it with speech
   • Ensures exact 15-second duration for consistency

4. Web Interface:

   • Flask backend handles file uploads and video processing
   • Modern UI built with HTML, CSS, and JavaScript
   • Background processing to avoid UI blocking
