Summary JJYB_AI 智剪 (JJYB_AI VideoAutoCut) is an open-source, AI-powered video editing suite for automated video creation, narration, and remixing. It targets power users and engineers seeking to streamline video production by integrating multiple AI models for content understanding, script generation, and voiceover synthesis. The tool offers a comprehensive solution with precise synchronization and extensive customization, aiming to professionalize AI video creation.

How It Works The project uses a layered architecture: a Flask frontend, a backend AI engine with diverse LLMs (9 options) and vision models (6 options), and a video processing layer (FFmpeg, MoviePy). A core feature is its precise synchronization mechanism (<100ms) for audio-visual and text-visual alignment. It supports multiple TTS engines, including offline options and voice cloning, for AI narration.

Quick Start & Requirements Installation involves running check_system.py then launching via 启动应用.bat or python frontend/app.py, accessible at http://localhost:5000. Minimum requirements: Windows 10/11 (64-bit), Python 3.9-3.11, 8GB RAM, 10GB disk. Internet is needed for dependencies and API calls. NVIDIA GPU is optional.

Highlighted Details
