MiniMax H3: A New Multimodal AI Video Model | Live on Pixmax Now
Blog
MiniMax H3 is MiniMax's new general-purpose multimodal AI video generation model. It accepts text, images, video clips, and audio as a single unified input and outputs video with native dual-channel audio — no separate audio generation or alignment step required. Starting today, Pixmax has integrated H3 on launch day, so you can start creating immediately without a separate MiniMax account or API key.
What Is MiniMax H3?
MiniMax H3 breaks away from the traditional approach, in which text-to-video, image-to-video, and video editing are split into separate modules. Instead, it treats a sentence, a reference image, a video clip, and an audio track as a single shared multimodal context, reads them together, and generates coherent output with built-in audio.
MiniMax describes H3 as a step toward "more general multimodal intelligence" — the breakthrough isn't about resolution or duration, but about how deeply the model understands creative intent.
Key Specs at a Glance
| Spec | Detail |
|---|---|
| Output duration | 5–15 seconds |
| Resolution | 768p (upgradable to 1440p) or native 1440p |
| Frame rate | 24 FPS |
| Audio | Native dual-channel audio on every output |
| Aspect ratio | First/last-frame follows input image; text-to-video and omni modes support 21:9 to 9:16 with auto mode |
| Reference inputs | Up to 9 images + 3 video clips (≤15s each) + 3 audio clips — 12 files max per task |
| Prompt length | Up to 7,000 characters |
Pixmax has seamlessly integrated MiniMax H3, eliminating the need for complex local deployments or code debugging. You can now directly invoke the MiniMax H3 model within the Pixmax Infinite Canvas.
Below are common scenarios where this integration delivers immediate value:
For teams producing e-commerce assets, brand ads, or short-drama content, the native audio and multi-file reference support streamlines your workflow by removing the friction of switching between separate video, editing, and audio tools.
3 Core Capabilities of MiniMax H3
1. True Multimodal Understanding & Generation
MiniMax H3 processes text, images, audio, and video simultaneously — reading the people, actions, sounds, emotions, camera language, and style across all inputs, then producing one cohesive output. A reference image, a reference voice, and a reference camera move no longer require three separate steps; one input covers it all.
2. Precise Multimodal Editing & Control
MiniMax H3 supports fine-grained edits to people, objects, scenes, sound, and pacing with strong instruction following. Creators can swap backgrounds, modify dialogue, adjust lighting, or add effects while the rest of the frame stays stable — dramatically shortening revision cycles.
3. Production-Grade Multi-Scenario Content
MiniMax H3 is built for real production pipelines — film, advertising, branding, e-commerce, and gaming. It handles on-screen text, subtitles, brand messaging, product showcases, and UI/UX motion demos. It works inside a real content workflow (concept testing, storyboard previews, pitch decks), not just as a standalone demo tool.
Why MiniMax H3 Matters
Most competition among AI video models over the past year has focused on specs — longer duration, higher resolution, smoother motion. MiniMax H3 takes a different path: it prioritizes understanding — how different modalities relate to each other, what a creator means by an edit, how visuals and sound should work together.
That's why Minimax H3's use cases span so widely: film trailers, fashion brand films, AI-driven short dramas, game UI demos, and product showcase videos. It isn't solving one narrow task — it's addressing the general problem of turning creative intent into finished audiovisual content accurately.

MiniMax H3 is a general-purpose multimodal AI model that generates video with native audio from text, images, video, or audio inputs used together in a single request.
Does H3 generate video with sound?
Yes. Every H3 output includes native dual-channel audio by default — no separate audio generation or syncing step required.
What resolution does MiniMax H3 support?
MiniMax H3 supports 768p (upgradable to 1440p) and native 1440p output at 24 FPS.
How long are MiniMax H3 videos?
Each generation produces a clip between 5 and 15 seconds.
How can I use H3 for free?
MiniMax H3 is available on Pixmax right now. Sign up and start using it directly — no separate MiniMax account needed.
How is MiniMax H3 different from other AI video generators?
Most AI video tools handle text-to-video, image-to-video, and editing as separate features. MiniMax H3 unifies text, image, video, and audio inputs into one context, so a single request can reference multiple materials and produce edited, sound-included output.
