Design AutoGen Multi-Agent Collaboration for Video Production

Design a multi-agent system using AutoGen for generating short-form video production plans. Define at least three distinct agent roles (e.g., 'Concept Creator', 'Scriptwriter', 'Visuals Lead') and their communication patterns. Specify which LLMs (Claude Opus 4.1 or OpenAI o3) would be best suited for each agent's primary task, explaining your rationale. Outline the initial user prompt flow and how human-in-the-loop feedback will be integrated into the workflow for iterative refinement. Describe how the final plan will be stored.
