A Python library for rendering dynamic code videos based on Manim

CodeVideoRenderer is a Python animation library specifically designed for creating dynamic code demonstration videos. It transforms static code into lively animations that simulate real programming processes.

✨ Core Features

• 🎬 Professional animation effects: Based on Manim engine, providing high-quality animation rendering
• 📝 Multi-language support: Syntax highlighting for various programming languages including Python, JavaScript, Java, and more
• ⚙️ Highly customizable: Adjustable typing speed, line spacing, camera behavior, and other parameters
• 🎨 Rich styling: Multiple code highlighting styles (such as github-dark, monokai, etc.)
• 🔧 Dual renderers: Support for both Cairo and OpenGL rendering backends

🚀 Quick Installation

Prerequisites

• Python 3.8+
• FFmpeg (required for video rendering)

Install FFmpeg first if you haven't:

# Windows
winget install ffmpeg

# macOS
brew install ffmpeg

# Linux
sudo apt update && sudo apt install ffmpeg

Install from PyPI

pip install codevideorenderer

💡 Quick Start

from CodeVideoRenderer import CameraFollowCursorCV

code = '''
def fibonacci(n):
    """Calculate the nth Fibonacci number"""
    if n <= 1:
        return n
    return fibonacci(n-1) + fibonacci(n-2)

# Example usage
result = fibonacci(10)
print(f"Fibonacci(10) = {result}")
'''

video = CameraFollowCursorCV(
    code=('string', code),
    language='python',
    formatter_style='github-dark',
    video_name='FibonacciExample'
)
video.render()

📋 Main Features

Code Animation

• Simulate typing process: Display code character by character, line by line
• Intelligent cursor tracking: Camera automatically follows cursor movement
• Syntax highlighting support: Integrates Pygments syntax highlighting engine

Camera System

• Auto-scaling: Automatically adjust camera zoom based on code content
• Smooth movement: Camera smoothly follows cursor movement
• Focus management: Intelligently recognizes code structure to ensure important parts remain visible

🎯 Use Cases

• Educational demonstrations: Create code explanation videos for programming courses
• Technical presentations: Make code demonstration segments for conference talks
• Algorithm visualization: Dynamically showcase algorithm implementation processes and logic
• Code review: Visualize code modifications and refactoring processes
