Remote access to MiniMax H3 via Codex is surprisingly smooth for video generation workflows. The setup includes official MiniMax prompt engineering skills built-in, so you can describe what you want and it automatically decides between text-to-video, image-to-video, and reference-to-video modes. It handles the entire pipeline: generates source images using Codex's own image tools when needed for i2v/ref2v, stitches clips together, and iterates until the output matches your spec. Basically turns your home PC into a headless video generation server you can drive from anywhere.
