H3 Max — AI video generator

MiniMax's fast video model, with sound on every clip

H3 Max is MiniMax's H3 video model, post-trained by fal for fast generation. It renders 5 to 15 seconds at 480p or 768p, generates a soundtrack with every clip, and expands your prompt before rendering — a balanced pass by default, a more careful one in quality mode, or none at all when you want your wording followed exactly.
