Run a model-agnostic, evidence-driven video production system across T2V/I2V/V2V/editing/reference/continuation, scripts and shot planning, ComfyUI workflow selection, controlled benchmarks, failure diagnosis, audio/speech/music/lip sync, upscaling, multi-shot assembly, and platform delivery. Use when Codex must turn a business or creative brief into controllable approved video rather than merely write one prompt. For MiniMax-H3 runtime use install-minimax-h3-local; use MiniMax's official h3-prompt-writing for current syntax and h3-production-prompt-compiler for production constraints and QA.
