The MiniMax H3 Video Model in Action: 2K Output, Real Audio, Full Control
The minimax h3 video model is MiniMax's open-weight, omni-modal engine, available from launch day on fal.ai. It processes text, stills, video, and audio in one pass, producing up to 15 seconds of 2K footage with matched audio, targeted edits, clean on-screen text, and up to 12 reference files.
- All Modalities in One Cohesive PassIn a single request, the minimax h3 video model ingests up to 9 pictures, 3 footage segments, and 3 audio tracks, blending subject, motion, camera, and sound into a seamless scene.
- Full Sound Design Built InEach clip from the minimax h3 video model includes composed music, spoken lines, sound effects, and room tone matched to the cut — plus the ability to clone a voice from an audio sample.
- Change Specific Areas OnlySwap an item, alter a sign, change a line of speech, or turn a daytime scene into night — the minimax h3 video model modifies just the specified area, leaving the remainder of the frame untouched.
Three Steps to Generate with the MiniMax H3 Video Model
Use the minimax h3 video model API to generate 2K clips with audio in three straightforward steps.
Core Capabilities of the MiniMax H3 Video Model
The minimax h3 video model bundles three generation endpoints, combined multimodal inputs, built-in audio, targeted editing, sharp text rendering, and flexible usage-based billing into a single fal.ai pipeline for 2K video.
Multiple Creation Modes
With the minimax h3 video model, you get text-to-video, image-to-video with start/end frame controls, and reference-driven generation — enough to support any creative workflow.
Twelve Channels of Context
Feed the minimax h3 video model as many as 9 pictures, 3 footage segments, and 3 audio files; it extracts character details, motion style, framing, and cutting rhythm from these references.
Crisp Text and UI Animation
The minimax h3 video model can draw legible captions, end cards, and logos, and it can animate actual UI components like landing pages, game menus, HUDs, and kinetic typography.
Expansive Prompt Capacity
Describe an entire sequence in one go: the minimax h3 video model accepts up to 7,000 characters of instructions, giving you detailed command over every scene.
High-Resolution Output at 24fps
Generate 2K footage with a 1440px short edge, running at 24 frames per second for up to 15 seconds, in six aspect ratios or an adaptive mode through the minimax h3 video model.
Flexible Pay-As-You-Go API
Access the minimax h3 video model through a serverless API with pay-as-you-go pricing — no monthly commitment, no minimum volume, and full commercial rights to the videos you generate.
MiniMax H3 Video Model: Common Questions Answered
Find quick answers about using the MiniMax H3 video model for AI video generation on fal.ai.
What exactly is the MiniMax H3 video model?
It's MiniMax's open-weight, all-in-one omni-modal model, offered on fal.ai from the very first day. The same engine handles text, imagery, motion, and sound together, producing 2K clips of up to 15 seconds with audio built in.
Which API endpoints are available for the MiniMax H3 video model?
The MiniMax H3 video model API exposes three paths: text-to-video, image-to-video with optional start and end frame control, and reference-to-video that preserves subjects, aesthetic, movement, camera behavior, and voice based on your reference files.
What video resolutions and lengths does it support?
You can generate 2K video with a 1440px short edge at 24 frames per second, lasting anywhere from 5 to 15 seconds. Supported ratios include 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16, plus an adaptive option.
Can the MiniMax H3 video model produce sound?
Absolutely. Every result from the MiniMax H3 video model includes stereo audio — composed music, speech, sound effects, and background atmosphere matched to the cut — and you can transfer or clone a voice from a sample recording.
How many reference inputs are supported?
You can provide up to 12 inputs in total: 9 images, 3 video clips (each 2–15s), and 3 audio tracks (each 2–15s). Just remember that audio needs at least one image or video alongside it when using the MiniMax H3 video model.
Is commercial use allowed for generated videos?
Yes. Videos created through the fal.ai API with the MiniMax H3 video model can be used in commercial projects, subject to fal.ai's terms of service.
