MiniMax H3 AI Video Generator with 2K and Stereo Audio
MiniMax H3, also known as Hailuo 03, unifies text-to-video, image-to-video, first-and-last-frame control, and multimodal reference generation. On Kuca, create 4–15 second videos in 768P or 2K with up to five reference images, three optional audio references, and native stereo sound.
One model for visual direction, references, and sound
MiniMax describes H3 as a general-purpose multimodal model that interprets relationships between text, images, audio, and the target video. Kuca exposes its production-ready video modes in one focused generator.
Unified multimodal understanding
Describe how subjects, motion, camera language, and sound references should work together. H3 uses natural language to interpret those relationships instead of forcing every creative request into a separate specialist task.
Native 2K detail
Choose 768P for faster exploration or 2K for fine textures and production detail. MiniMax uses in-context regeneration so the base model can revisit the original context while recovering high-resolution information.
Native stereo audio
Generate voice, ambience, effects, and music together with the visuals. Stereo placement and audiovisual timing help movement, cuts, dialogue, and environmental sound belong to the same scene.
Flexible 4–15 second shots
Set any duration from 4 through 15 seconds and choose a cinematic, square, landscape, or vertical aspect ratio. First-frame, last-frame, and reference modes add more control when text alone is not enough.
Build a clear generation brief
Decide which mode matches the job, give each reference a distinct role, and write camera and sound instructions as one coordinated sequence before generating.
Choose the right starting mode
Use text-to-video for open exploration, a first frame for composition and identity, first-and-last frames for a directed transition, or multimodal reference mode when images and audio must guide the same result. Decide what must remain fixed before choosing: a product silhouette benefits from a clean first frame, while a transformation with a defined destination needs both boundary frames. Use reference mode only when each uploaded asset contributes information that the prompt cannot express precisely.
Assign every reference a purpose
MiniMax H3 accepts up to five reference images and three optional audio files in Kuca. State whether each asset controls a character, product, environment, visual style, voice, music, ambience, or sound effect. Prepare images with a clear subject, useful lighting, and as little visual obstruction as possible. Trim silence and unrelated passages from audio, then resolve conflicts explicitly—for example, one image controls identity while another supplies only palette and composition.
Write motion in chronological order
Describe the opening state, primary action, camera move, change in the scene, and closing frame. Keep subject names and visual traits consistent, and leave enough time for each movement to resolve within 4–15 seconds. On the first review, check whether the central action actually finishes before judging texture or polish. If it feels rushed, remove a secondary action or extend the duration; if identity drifts, strengthen the frame or reference instruction instead of rewriting every style cue.
Direct the stereo soundstage
Name the dialogue, room tone, effects, and music you need, then describe where important sounds occur and how they follow the image. Review duration, resolution, and aspect ratio together before submitting. Compare the first result in layers: composition and continuity first, then hands and small details, and finally dialogue timing, stereo position, ambience, and music balance. Change one category at a time and keep successful wording and settings as the baseline for the next variation.
Explore official model outputs
A 2K macro wildlife portrait
An official MiniMax H3 sample holds fine detail across a crested gecko's eye, scales, and tongue movement. Use the example prompt to explore controlled studio light, shallow focus, and precise natural motion.
A stereo retro-futurist tower
A vertical camera move through a mechanical tower demonstrates the model's native stereo presentation. Try the prompt to coordinate spatial ambience, machinery, lighting, and a continuous architectural move.
A neo-noir film opening
MiniMax's film-title example combines graphic panels, typography, silhouettes, objects, and rhythmic cuts. The prompt turns those ingredients into a concise opening sequence with synchronized sound direction.

Develop title sequences, mood films, and pitch-ready visual directions with coordinated montage, typography, transitions, and sound.
Product websites
Create animated product moments, feature demonstrations, interactive-looking scenes, and launch visuals for digital experiences.
Animated posters
Turn static key art and character designs into looping vertical posters with controlled depth, motion, framing, and atmosphere.
Advertising and e-commerce
Build product reveals, lifestyle shots, branded transitions, and campaign variants from reference images and a precise creative brief.
Games and virtual worlds
Previsualize characters, interfaces, environments, cutscenes, and stylized motion before committing to a full production pipeline.
Education and explainers
Combine clear visual steps, narration, effects, and consistent subjects for demonstrations, lessons, and short concept explanations.
Frequently Asked Questions About MiniMax H3
MiniMax H3 is MiniMax's general-purpose multimodal generation model, also presented as Hailuo 03. It unifies video generation, references, editing relationships, and jointly generated native stereo audio.
Kuca supports text-to-video, first-frame image-to-video, first-and-last-frame generation, and multimodal reference generation with images and optional audio.
The MiniMax H3 generator on Kuca supports 768P and 2K. Use 768P for quicker exploration and 2K when the output needs stronger texture and fine-detail fidelity.
On Kuca, MiniMax H3 supports any whole-second duration from 4 to 15 seconds, letting you match the shot length to a quick motion, product moment, transition, or complete short scene.
Yes. MiniMax H3 jointly generates native stereo audio, including voice, ambience, sound effects, and music, so sound can follow on-screen movement and scene changes.
Yes. Upload a first frame to animate a composition, or add both first and last frames when the video must travel between two defined visual states.
Kuca's MiniMax H3 reference mode accepts one to five images and up to three optional WAV or MP3 audio files. Reference images are required in that mode.
Text and reference generation support 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. Reference mode also offers adaptive framing, while image modes follow the uploaded frame.
Write a compact production brief: identify the subject and setting, describe action and camera movement in order, specify the visual treatment, then add dialogue, ambience, effects, and music cues.
Yes. The capability and example videos on this page come from MiniMax's official H3 release materials. The example prompts are Kuca-ready briefs written to explore the visible capability in the locked MiniMax H3 generator.
Start with clean source files that each have one obvious job. Use a well-lit image with an unobstructed subject when identity or product shape matters, and keep style references visually consistent with the intended scene. For audio, trim silence and unrelated material so a voice, music cue, ambience, or effect is easy to identify. Name the role of every file in the prompt instead of expecting the model to infer it. If two references conflict, state which controls subject identity and which controls color, composition, movement, or sound. A small, deliberate reference set is usually easier to direct than five unrelated images and three competing audio tracks.
Review the output in layers. First check subject identity, composition, and whether the main action finishes within the selected duration. Then inspect camera direction, motion continuity, hands and small details, followed by dialogue timing, stereo placement, ambience, and music balance. Change one category of instruction at a time so you can tell what improved the result. If the shot feels rushed, simplify the action or increase duration before adding detail. If the image drifts, strengthen the first frame or reference role. Keep successful wording, resolution, aspect ratio, and reference assignments as a reusable brief for the next variation.
