Key Reasons to Choose the MiniMax H3 Video Model
The MiniMax H3 video model from MiniMax is an open-weight, all-purpose multimodal engine that runs as a Day 0 ecosystem partner on fal.ai. With text, stills, moving images, and sound in one context, it outputs 2K clips with native stereo audio for up to 15 seconds. The model also handles targeted edits, crisp text and UI rendering, and accepts as many as 12 multimodal references per job.
- A Single Context for All Media TypesThe MiniMax H3 video model can take up to nine images, three clips, and three audio tracks in one run, blending appearance, acting, camera movement, and audio into a single coherent output.
- Built-In Stereo SoundEach generation from the MiniMax H3 video model includes unique music, speech, sound effects, and background ambience that are synchronized with the edit, and it can transfer or clone voices from reference audio.
- Targeted Region EditingSwap out items, change text on signs, alter speech, or turn daylight into night — the MiniMax H3 video model modifies only the selected area while the rest of the image remains stable.
A Simple Workflow for the MiniMax H3 Video Model
Run the MiniMax H3 video model API in just three steps and generate 2K videos with audio that lines up perfectly.
MiniMax H3 Video Model: Feature Highlights
From three endpoints and a shared multimodal context to native stereo audio, accurate localized edits, sharp on-screen text, and pay-as-you-go pricing, the MiniMax H3 video model provides a full 2K generation pipeline on fal.ai.
Three Flexible Creation Endpoints
The MiniMax H3 video model exposes text-to-video, image-to-video with first/last-frame control, and reference-to-video endpoints, covering every common workflow.
Support for Up to 12 References
Blend up to nine stills, three video clips, and three audio tracks; the MiniMax H3 video model pulls character, acting, camera motion, framing, and cutting pace from those references.
Crisp Text and Interface Rendering

Long-Form Prompts (Up to 7,000 Characters)
Describe an entire shot-by-shot plan in one API request, since the MiniMax H3 video model supports 7,000-character prompts for precise scene direction.
2K Output at 24fps
Generate 2K footage with a 1440px short side, lasting up to 15 seconds at 24fps, and choose from six preset aspect ratios or adaptive sizing on the MiniMax H3 video model.
Flexible Pay-Per-Use Pricing
Access the MiniMax H3 video model through serverless, per-use pricing without minimums or subscriptions, and you retain commercial rights to your generated videos.
MiniMax H3 Video Model — Questions and Answers
Quick answers to the most common questions about the MiniMax H3 video model API and how it behaves on fal.ai.
What exactly is the MiniMax H3 video model?
It's an open-weight, general-purpose multimodal generation model from MiniMax, available on fal.ai from Day 0. The model handles text, images, video, and sound within one context, creating 2K clips with built-in stereo audio for up to 15 seconds.
Which API endpoints does it provide?
The MiniMax H3 video model gives you three endpoints: text-to-video, image-to-video (with optional first/last-frame control), and reference-to-video, which preserves subjects, style, motion, camera angles, and voices from your uploaded references.
What resolutions and clip lengths does it support?
The MiniMax H3 video model outputs 2K (1440 pixels on the short edge) at 24fps, runs from 5 to 15 seconds, and supports aspect ratios like 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, plus adaptive.
Does the MiniMax H3 video model generate audio?
Yes, every render includes native stereo audio — fresh music, dialog, sound effects, and ambience matched to the edit — and it can transfer or clone voices from reference audio.
How many reference inputs are allowed?
You can include up to 12 references: 9 images, 3 video clips (2–15s each), and 3 audio tracks (2–15s each). The MiniMax H3 video model requires audio to be paired with at least one image or video.
Can the generated videos be used commercially?
Yes, you can use the content you create through the fal.ai API with the MiniMax H3 video model for commercial work, as outlined in fal.ai's terms of service.
