MiniMax H3
MiniMax H3 turns text, images, audio, and short clips into finished videos with native stereo sound in one pass. You can describe a scene in plain language or upload up to nine images, three video clips, and three audio tracks so the model reads faces, motion, and style together. It targets creators, marketers, and studios who need short cinematic clips without building a traditional editing pipeline.
Most video generators output silent clips and handle each input type separately. MiniMax H3 blends multimodal references in a single request and ships dialogue, ambience, and effects on every render. You can also swap a background, relight a scene, or rewrite a line of dialogue by typing an instruction, and the footage you did not mention stays stable.
The tool fits fast creative iteration: social teams testing vertical ad concepts, e-commerce sellers animating product photos, and filmmakers previsualizing shots with real camera language like rack focus and hard cuts. Clips run 5 to 15 seconds at up to 1440p and 24 FPS, which matches ad cutdowns and storyboard reels more than long-form editing.
