MiniMax H3 Video Generator is a web-based AI tool that converts text prompts into 2K-resolution video clips with native stereo audio, supporting 5, 10, and 15-second durations.
What is MiniMax H3 Video Generator?
MiniMax H3 Video Generator is a web application built around the official MiniMax H3 model. It takes a text description (up to 2,000 characters for scene direction) as input and generates a video clip at 2K resolution with synchronized stereo audio. The tool supports six aspect ratios: 16:9, 9:16, 4:3, 1:1, 3:4, and 21:9. The output is an MP4 file that can be previewed and downloaded. The platform runs entirely in the browser and requires a signed-in account to generate.
Key Features
- Native 2K output — Every render produces a 2K-resolution video with selectable duration of 5, 10, or 15 seconds.
- Stereo audio included — MiniMax H3 generates native stereo audio with the clip, so sound and visuals are created from the same prompt.
- Six cinematic aspect ratios — Choose from widescreen 16:9, vertical 9:16, square 1:1, classic 4:3, portrait 3:4, or ultrawide 21:9.
- Prompt library — 56 production-ready prompts organized by categories like Cinematic, Nature, People, Product, Food, Travel, Sci-fi, and Fantasy & animation, with one-click copy.
- Predictable credit costs — A 5-second render uses 150 credits, 10-second uses 300, and 15-second uses 450; failed provider tasks automatically restore credits.
- Private workspace — Prompts and outputs are tied to your account and never appear in a public gallery.
- Daily rewards and referrals — Daily check-ins accumulate up to 33 credits over a seven-day cycle, and referral bonuses give both accounts extra credits.
