What Is MiniMax H3?
MiniMax H3 is an omni-modal AI video generator that reads text, images, video, and audio in a single context and returns 2K video with native stereo sound. Instead of producing a silent clip and leaving audio work to you, H3 writes picture and sound in the same pass — dialogue, room tone, music, and effects arrive already synced to the frame.
Key Capabilities
- Native 2K at 24fps — output up to 2560×1440, rendered at that resolution rather than upscaled afterward.
- Stereo audio in one pass — every clip returns aligned dialogue, ambience, music, and effects.
- Up to 12 mixed references — 9 images, 3 video clips, and 3 audio tracks, each tagged in the prompt for a specific job.
- Instruction-based editing — describe a change and the rest of the frame stays put, no full re-roll required.
- Legible on-screen text — subtitles, packaging copy, logos, and animated UI elements hold up.
- Six aspect ratios — 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16 from the same model.
- 5–15 second clips with prompts up to 7,000 characters.
Five Ways to Generate
- Write a prompt and generate.
- Animate a single still image.
- Set a first and last frame and fill the motion between.
- Attach and tag reference media for continuity, choreography, color, or timing.
- Apply a LoRA online for specialized motion, action, realism, or style.
Models and Pricing
Five engines are available — Standard, Open Weight, Max, Max Turbo, and LoRA Online — differing on resolution, speed, and open-weight support. Credits cost 4 per second at 2K and 2 per second at 768P, with no subscription and no expiry. New accounts get 20 credits, enough for one 5-second 2K clip with audio, no card required.
Who It Suits
Content creators posting daily, marketers testing many directions before producing one, ecommerce sellers animating catalog photos, game and app teams building character reels and UI walkthroughs, and film teams previsualizing shots with real camera vocabulary.
