What is h3max.io?

H3Max is an independent web tool for generating short AI videos with the MiniMax H3 Max model. It creates 5–15 second clips from a text prompt or an opening frame, with an optional ending frame to guide the finish. Output renders at 480P or 768P, 24 FPS, with native synchronized audio in the same generation. It also bundles access to other video and image models such as Seedance, Wan, Kling, Seedream, GPT Image, and Nano Banana.

How to use h3max.io?

1. Write the shot or upload a first frame: describe subject, action, setting, camera, lighting, and sound; add an ending frame only when the finish needs direction. 2. Choose settings and estimate credits: select 480P or 768P, a 5–15 second duration, and an aspect ratio (H3 Max costs 10 credits per second). 3. Play, inspect, and iterate: unmute the result and check action order, subject identity, camera motion, and synchronization, changing one variable at a time before regenerating. Switch to standard H3 for multi-reference input or editing existing clips.
