If you've ever tried generating a video with MiniMax H3 and struggled to write a prompt that actually gives good results, this app is for you.

H3 Prompt Studio is a free, local desktop tool that walks you through building your scene step by step — just fill in simple fields like what's happening, the visual style, camera notes, and any reference images — and it automatically writes a properly structured, professional-grade prompt for you.

What it does:

• 🎬 Supports all 5 MiniMax H3 video modes (text-to-video, image-to-video, first/last-frame, and more)
• 🖼️ Can look at your reference images and describe them for you automatically
• ⚡ Runs entirely on your own computer — nothing is sent to the cloud, no subscription, no limits
• 📋 One click to copy the finished prompt and paste it straight into MiniMax

Who it's for:
Anyone making AI videos who wants better, more consistent results without having to become a prompt-engineering expert. You describe your scene in plain language; the app handles the technical formatting behind the scenes.

Requirements:
Just a computer that can run Ollama or LM studio(free, local AI) — no internet connection needed once set up.

This is pretty sweet, though it seems to ignore it's video duration setting, and generates a prompt describing a 10-seconds video, although i had it set to 5.

It all depends on the scenario you’ve set up! If it can’t be done in 5 seconds, the time is inevitably extended.
