MiniMax H3

MiniMax H3 — AI Video Generator with Native SoundMiniMax H3 is a general-purpose multimodal AI video generator that turns text, images, video clips, and audio into finished cinematic scenes. Every generation ships with native stereo audio — ambience, effects, music, and synced dialogue already in place — so there's no separate sound design pass.What makes it differentTrue multimodal input — mix up to 9 reference images, 3 video clips, and 3 audio tracks in a single request. H3 reads your characters, choreography, camera moves, and voices together and blends them into one coherent take.Instruction-based editing — swap a character, relight a scene, replace a background, or rewrite a line of dialogue in plain language. Everything you didn't touch stays pixel-stable, so you iterate shot by shot like a director giving notes.Commercial-grade output — up to 1440p at 24 FPS, with on-screen text, logos, and product detail rendered cleanly enough for ads and e-commerce listings. Aspect ratios from 21:9 down to 9:16.Who it's forContent creators shipping daily shorts, marketers validating ad concepts, e-commerce sellers turning product photos into listing videos, game teams producing character PVs, and filmmakers previsualizing scenes. No timeline, no keyframes, no software to install — the MiniMax H3 video generator works from a sentence.If you can describe it, H3 can film it.Start free with signup credits — no credit card required.
