What Is MiniMax H3? 2K Multimodal AI Video with Native Sound
MiniMax H3 is a general-purpose multimodal generation model for complete audiovisual scenes. It understands text, images, video, and audio in one shared context and generates 4–15 second video at 768P or 2K with native stereo sound.

That combination makes H3 different from a conventional text-to-video model. A creator can provide a character image, a reference camera movement, an audio clip, and written instructions explaining how those materials should work together.
This guide explains what H3 can do, how it differs from earlier Hailuo models, where it is useful, and how to write prompts that take advantage of its multimodal capabilities.

What is MiniMax H3?
MiniMax H3 is the latest generation of MiniMax video technology, following the Hailuo 01 and Hailuo 02 families. Earlier systems often separated text-to-video, image animation, motion transfer, voice, and music into unrelated tools.
H3 instead places those inputs inside a unified multimodal context. The creator describes relationships in natural language: use the person in one image, follow the camera movement in a video, and match the voice and timing from an audio reference.
MiniMax describes this as a move from specialized video tasks toward a general-purpose generation model. Read the official H3 launch article.
Why MiniMax H3 matters
The biggest change is not simply higher resolution. H3 shifts the unit of creation from an isolated visual clip to a directed audiovisual scene.
A product or character image
A first and final frame
A video showing motion or camera behavior
Audio demonstrating a voice or rhythm
Written instructions connecting every reference
Dialogue, ambience, effects, and music requirements
MiniMax H3 key features
1. Unified text, image, video, and audio inputs
Images can communicate identity, product appearance, styling, or a starting frame. Videos can communicate motion, camera behavior, timing, or editing rhythm. Audio can define voice and sound references.
Text connects those materials by explaining what the final video should contain and how each reference should influence it.
2. Native stereo audio
Many video tools create a silent clip or add an independently generated soundtrack afterward. H3 models visuals and audio together.
The scene can include speech, effects, ambience, and music. Lip synchronization and exact sound timing still need review.
3. Video generation up to 2K
The 2K option is useful for landing-page videos, advertisements, product presentations, design pitches, and footage intended for further editing.
Resolution is not the same as accuracy: small text, product details, faces, and hands can still drift between frames.
4. Four- to fifteen-second videos
The duration range covers six-second product reveals, eight-second ads, ten-second character interactions, and longer cinematic concepts.
Longer clips create more storytelling space and more opportunities for visual drift, so focused scenes remain easier to control.
5. First-and-last-frame generation
A first frame anchors the opening shot. A last frame gives the generation a visual destination for transformations, reveals, lighting changes, and planned transitions.
The frames should use compatible subjects and composition; extreme differences can force an unstable transition.
6. Reference-guided motion and style
A reference video can demonstrate a camera orbit, body movement, editing rhythm, product reveal, or relationship between motion and music.
The prompt should identify the part that matters instead of asking the model to copy the entire reference without direction.
The official MiniMax API documentation lists current reference counts, file formats, dimensions, and size limits.

How to write MiniMax H3 prompts
Treat the prompt as a timed audiovisual sequence: subject + setting + action + camera + timing + dialogue + sound + visual style + preservation rules.
Subject and setting
Weak
A perfume ad.
Better
A rectangular amber perfume bottle stands on a polished black stone platform inside a dark studio.
Action
Weak
Make it cinematic.
Better
Condensation slowly appears on the glass while a thin layer of mist moves behind the bottle.
Timing
Weak
Show the whole product.
Better
During the first three seconds, focus on the embossed logo. Pull back to reveal the bottle, then hold the final composition for two seconds.
Dialogue and sound
Weak
Add epic music.
Better
A calm voice says, “Designed for the hours after sunset.” A glass chime plays when the logo catches the light, with minimal music below the voice.
Preservation instructions
Weak
Keep it consistent.
Better
Preserve the exact bottle geometry, label text, logo, cap, colors, and material. Do not add new lettering or redesign the packaging.
MiniMax H3 prompt examples
Product video prompt
Use the uploaded running shoe image as the product reference. Keep the shoe centered on a dark stone platform while the camera moves from a side view to a three-quarter front view. A narrow band of light travels across the upper and sole. Add a subtle impact sound followed by restrained electronic music. Preserve the exact shoe design, logo, laces, material, stitching, colors, and sole structure. Premium sportswear advertisement, 8 seconds, 16:9.
Character dialogue prompt
Use the uploaded character image as the identity and style reference. The character stands beside a train window at night, turns toward the camera, and quietly says, “We missed the last station.” Match the lip movement to the sentence. Add train movement, rain against the glass, and a low ambient tone. Preserve the face, hairstyle, clothing, proportions, and illustration style. Slow push-in, 7 seconds.
Animated poster prompt
Animate the uploaded event poster without changing its design. Colored light moves behind the headline while smoke travels across the lower background. Small geometric elements pulse with the music. Keep every word, logo, date, and typographic element readable and in its original position. End with a two-second hold. Electronic music, 6 seconds, 9:16.
Common prompting mistakes
Adding too many events
A fifteen-second prompt should not contain several locations, five characters, dialogue, a transformation, and multiple camera cuts. Give each generation one clear purpose.
Using vague audio instructions
Describe the intended music, timing, volume, and relationship to the visible action instead of only asking for cinematic audio.
Forgetting preservation rules
Explicitly constrain packaging, faces, costumes, materials, colors, and visible text that must remain consistent.
Requesting conflicting camera moves
Begin with one dominant movement instead of combining a push-in, zoom-out, orbit, track, and handheld direction.
Expecting perfect typography
Provide a clear reference, keep layouts simple, and inspect every visible word before publishing.
MiniMax H3 limitations
H3 expands what can fit inside one request, but it does not eliminate the known risks of generative video. Hands, facial identity, product labels, small text, lip synchronization, sound timing, object continuity, and physical contact can still become unstable.
For commercial projects, treat the first output as a production draft. Generate focused variations and use conventional editing tools for final typography, logos, color, sound mixing, and compliance.
Is MiniMax H3 open source?
MiniMax released the complete H3 model weights on August 2, 2026. The weights use the MiniMax H3 Community License, which includes geographic and usage conditions. “Open weights” does not automatically mean an unrestricted Apache- or MIT-style license.

A broader audiovisual production model
MiniMax H3 represents a shift from isolated text-to-video generation toward multimodal audiovisual production. It is especially relevant to product advertising, animated posters, social creative, character scenes, and early cinematic concept development.
Focused scenes, clear timing, explicit preservation rules, and careful review still matter. H3 provides more forms of control, but those controls must be communicated precisely.
