MiniMax H3 Max is a speed-optimized AI video generation model built on MiniMax H3 and post-trained by fal. It converts text prompts or still images into short videos — 5 to 15 seconds long, at up to 768p resolution — with native synchronized audio generated in the same pass as the visuals.
Its standout feature is speed: a 5-second, 768p clip renders in under 3 seconds, roughly 35x faster than the official MiniMax H3 endpoint. Despite this speed, it currently ranks #1 for image-to-video quality on two independent leaderboards — Design Arena (Elo 1,341) and Artificial Analysis' image-to-video board with audio (Elo 1,201).
Key features:
- Text-to-video & image-to-video — generate from a written prompt or animate a starting image, with output following the source image's aspect ratio
- First-to-last-frame control — provide a starting and ending frame to guide precise transitions
- Native synchronized audio — dialogue, ambience, and sound effects generated together with the video, not added afterward
- Strong prompt adherence — tuned to closely follow detailed creative direction (camera movement, action, environment, sound)
MiniMax H3 Max is aimed at creators who want fast iteration without sacrificing prompt accuracy or output quality — ideal for testing shots, previz, and rapid content creation, with the option to switch to standard MiniMax H3 for 2K resolution or reference-driven editing.
