What is h3max.io
h3max.io is an independent web-based AI video generator that uses the MiniMax H3 Max model to create 5–15 second videos from text prompts or images. It renders at 480P or 768P at 24 FPS with native synchronized audio in the same generation. The platform is not an official MiniMax or fal website.
How to use h3max.io
- Write the shot or add a first frame – Describe the subject, action, setting, camera, lighting, and sound. For image-to-video, upload an opening frame and optionally an ending frame to guide the finish.
- Choose settings and estimate credits – Select 480P or 768P, a duration between 5 and 15 seconds, and an aspect ratio. H3 Max costs 10 credits per second, so the cost is visible before submission.
- Play, inspect, and iterate – Unmute the result and review action order, subject identity, camera motion, and synchronization. Change one variable at a time before running again.
