MiniMax H3
hailuo/minimax-h3MiniMax H3 (Hailuo 03) is a unified multimodal video generation model that turns text, images, video, and audio references into polished 2K videos with native stereo sound. Build original scenes, animate stills, edit existing footage, and run it all through one MiniMax H3 API.
What Sets the MiniMax H3 API Apart
MiniMax H3 unifies text, images, video, and audio in a single creative context, so every element of a scene stays connected from prompt to final render.
Unified Multimodal Context
Interpret text, images, video clips, and audio recordings in the same request. Each input can define character identity, motion, camera language, visual style, or sound.
Native 2K Video and Stereo Audio
Generate up to 2K video together with native stereo sound — no separate audio pass. Dialogue, music, ambience, and effects stay synced with the visuals.
Flexible Multi-Reference Control
Combine multiple images, clips, and audio files in one generation. Assign identity from an image, motion from a clip, and voice from an audio reference.
Strong Instruction Following
Follow detailed directions for shot order, timing, transitions, camera movement, and elements that must stay unchanged, with clearer text and brand rendering.
Precise Video Editing
Apply targeted changes to existing footage — replace subjects, backgrounds, lighting, dialogue, or wardrobe — while preserving the rest of the composition.
Three Generation Modes
Text to Video, Image to Video (single frame or first-and-last frames), and Reference to Video cover every stage of a creative workflow.
MiniMax H3 Video Showcase
Real clips generated by the MiniMax H3 API across film, advertising, and motion poster use cases. Enable sound to hear native stereo audio.
MiniMax H3 use cases
MiniMax H3 is built for short, high-fidelity video — product films, ads, and social clips where shot coherence and motion quality matter.
Product showcase films
A spinning ceramic lamp, a sweeping phone reveal — H3 holds product detail across a 5–10s shot.
Ad creative
Generate vertical 9:16 ad variants from a prompt plus a reference image, then cut a campaign in an afternoon.
Social short-form
2K clips for Reels and Shorts where texture and lighting read well even on mobile.
Storyboard previews
Draft at 768p to block out shots cheaply, then render the keepers at 2K.
MiniMax H3 vs Seedance 2.0
Given similar creative direction, MiniMax H3 and Seedance 2.0 arrive at noticeably different visual solutions across product storytelling, motion design, and cinematic style.
| Use Case | MiniMax H3 | Seedance 2.0 |
|---|---|---|
| Product Storytelling | Structured commercial with varied angles, close-up feature shots, and consistent materials | Polished studio presentation with simpler shot progression |
| Motion Design | Denser sequence: grids, fluid forms, bold typography, rapid compositions | Cleaner geometric transformations, restrained layouts |
| Cinematic Style | Commercial realism with realistic materials and technical overlays | Futuristic styling, glowing blueprint and holographic effects |
| Interface Animation | Preserves original webpage structure, typography, and controls | Reimagines the material into a standalone product ad |
Qualitative comparison of creative strengths, not a formal benchmark.
MiniMax H3 API Pricing
Usage-based pricing for video generation and input. Pay only for what you generate.
Total cost = unit price × (generated video duration + input video duration) + additional image cost. The first 5 input images are free; input audio is free.
- Draft at 768p, deliver at 2K — 768p costs ~38% less per second and is enough to lock composition.
- You're billed per second of generated video — a 6s clip at 768p is about $0.88.
- Image-to-video with a reference frame is steadier than pure text-to-video for product shots.
- Duration maxes out at 15s per clip — split longer sequences into multiple runs.
MiniMax H3 API
Send a POST request to /api/v1/runs with your API key and input. Generation runs asynchronously — poll the run ID for status, then read the output URLs when it succeeds.

How to Use the MiniMax H3 API
Move from experimentation to production in five steps.
- 1
Register and Secure Your API Key
Create a Runbase account or sign in, then generate an API key from the dashboard. Store the key securely and keep it out of any client-side environment.
- 2
Validate Creative Settings in Playground
Test Text to Video, Image to Video, and Reference to Video before writing code. Try prompts, single images, first-and-last frames, and multimodal references.
- 3
Configure Your Inputs
Define the prompts, media formats, generation modes, and settings your product will support so each creative request is routed correctly.
- 4
Integrate the MiniMax H3 API
Connect the validated generation flow to your app or platform. Wire up authentication, input processing, progress handling, and output presentation.
- 5
Deploy and Scale
Launch in production, then refine prompt templates, validation rules, and capacity as usage grows. Check the latest documentation for current parameters.
