A complete AI-powered video generation pipeline that enhances creative prompts and generates high-quality videos using Google's Veo3 API, requiring only a single API key.

VEO3 Workflow Agents

Workflow agents for AI video prompt enhancement and video generation using Google's Veo3 Fast API. This project combines multiple AI agents to create a comprehensive video generation pipeline:

• Enhancement agent: langraph_agents/ - Technical prompt enhancement with cinematography details
• Idea generation agents: pydantic_ai_agents/ - Creative prompt variations and viral content ideas
• Veo3 Integration: Complete notebook workflow for generating videos using Google's latest video AI
• Interactive Interface: Jupyter notebook with user-friendly UI for the complete workflow

🎬 NEW: Streamlined Veo3 Video Generation Notebook

We've created a streamlined Jupyter notebook that integrates prompt generation, enhancement, and video creation with zero Google Cloud setup required:
