Overview

h3minimax.com is an independent web app that provides a simple interface to the MiniMax H3 video model. You write a text prompt or upload a first and/or last frame image, choose duration and resolution, and the service submits the task through a third-party API provider, tracks it, and shows the finished clip in your browser. It is for creators who want short AI-generated videos for drafts, product clips, e-commerce visuals, storyboards, and social posts.

How it works

The generator offers two modes: text-to-video and image-to-video. For text-to-video, you write a prompt up to 7,000 characters describing the subject, setting, motion, and camera, and choose a duration from 4 to 15 seconds, a resolution of 768P or 2K, and one of six aspect ratios: 21:9, 16:9, 4:3, 1:1, 3:4, or 9:16. For image-to-video, you upload a first frame, a last frame, or both as JPEG, PNG, or WebP files up to 5 MB and 256–5760 px per side, and the model animates the moment in between.

Key capabilities

The service supports only documented MiniMax H3 settings: two modes, 4–15 second durations, 768P or 2K resolution, and the six text-to-video aspect ratios. Image-to-video follows the aspect ratio of the uploaded frame. Prompts and uploads are screened before generation, and prohibited content includes sexual material, anything involving minors, and a real person's likeness without consent. Every generation is saved to your history.

Who it is for

This tool is for creators who need short AI-generated clips for product shots, e-commerce visuals, storyboards, social posts, and testing scene ideas before a full production. It is also useful for anyone who wants to experiment with the MiniMax H3 model without dealing with API details. The service is independent and not affiliated with MiniMax, and it accesses the model through a third-party API provider.
