MiniMax H3 is a multimodal AI video generator that turns text, images, video, and audio references into 2K video with native stereo sound.
Unlike tools that only animate a single still image, H3 treats all four input types as one creative context. Start from a text prompt alone, control the opening and closing frames with images, or attach reference media to hold a character's face, a product's design, a motion style, or a specific voice steady across multiple shots. Picture and audio are generated in the same pass, so dialogue lands on mouth movements and sound effects are timed to what happens on screen — no separate foley or lip-sync step afterwards.
What you can do:
- Text to Video — describe subject, action, camera, lighting, pacing, dialogue, and ambience, and get a finished shot
- Image to Video — animate approved artwork, a storyboard frame, or a product photo without losing the original direction
- First & Last Frame — set the start and end states and let the model fill the motion between them
- Reference to Video — combine image, video, and audio references to keep identity, motion language, and voice consistent
- Instruction editing — change a color, swap a background, or retime an action by describing it in words
Clips run 4 to 15 seconds and render at 2K, downloadable as MP4 for publishing or further editing. Free credits to start, then one-time credit packs that never expire — no subscription. Runs entirely in the browser.
