Why the minimax h3 video model stands out
As an open-weight omni-modal system from MiniMax, the minimax h3 video model runs through fal.ai and accepts text, stills, motion footage, and sound in one shared context. It renders 2K results with native audio in clips up to 15 seconds, supports targeted edits to specific areas, handles clean typography and UI screens, and can combine up to 12 reference inputs per request.
- Unified multimodal contextFeed the minimax h3 video model up to nine stills, three moving shots, and three soundtracks in one pass — it merges faces, acting, camera motion, and audio into a single consistent output.
- Full audio in the outputEach clip from the minimax h3 video model includes its own score, speech, sound effects, and room tone locked to the footage, plus voice cloning or transfer from uploaded audio references.
- Targeted frame editsSwap a logo, alter text on a sign, re-record a line, or shift daylight to darkness — only the chosen zone changes and everything else keeps its original consistency.
Getting started with the minimax h3 video model
Follow three quick calls to the minimax h3 video model API and receive 2K footage with matching sound.
Capabilities that define the minimax h3 video model
With three endpoints, a shared multimodal context, audio rendered in the clip, spot edits, sharp on-screen text, and usage-based billing, the minimax h3 video model gives you a full 2K production workflow through fal.ai.
Three ways to start a generation
Work from plain text, an existing image (with optional start/end frame settings), or a set of reference materials — the minimax h3 video model exposes all three endpoints for any pipeline.
Twelve reference inputs at once
Include nine pictures, three video files, and three audio tracks in one request; the minimax h3 video model extracts faces, motion, framing, style, and pacing for the output.
Clean text and screen rendering
Generate crisp captions, end cards, logos, and on-screen copy, or bring actual interfaces to life — websites, game menus, heads-up displays, and kinetic type using the minimax h3 video model.
Long-form prompt support
Write an entire storyboard in one prompt: the minimax h3 video model accepts up to 7,000 characters so you can steer every scene detail.
2K output at 24 frames per second
Render footage with a 1440px short edge, run as long as 15 seconds at 24fps, and choose from six aspect ratios or adaptive sizing in the minimax h3 video model.
Usage-based API billing
You only pay for what you render: the minimax h3 video model uses serverless per-request pricing with no monthly commitment and full commercial rights to your results.
Your questions on the minimax h3 video model, answered
Straight answers about running the minimax h3 video model through fal.ai, covering endpoints, output quality, audio, limits, and licensing.
What exactly does the minimax h3 video model do?
It's an open-weight, all-in-one generation system from MiniMax, available on fal.ai as a Day 0 launch partner. The model takes text, pictures, footage, and sound in a single context and turns them into 2K clips with built-in audio, each up to 15 seconds.
Which API endpoints are available?
There are three routes into the minimax h3 video model: text-to-video, image-to-video with optional start/end frame constraints, and reference-to-video that keeps subjects, look, movement, camera angles, and voices consistent with uploaded samples.
What output sizes and clip lengths can I use?
You can render 2K (1440px on the short side) at 24fps for 5 to 15 seconds, using any of these aspect ratios: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, or adaptive sizing.
Is audio generated automatically?
Yes. Every run of the minimax h3 video model produces two-channel audio — composed music, spoken lines, sound effects, and room tone matched to the cut — and you can also transfer or clone a voice from reference audio.
What are the limits for reference files?
You can supply nine images, three video clips, and three audio tracks in a single request — 12 references maximum. Each clip or audio file should run 2 to 15 seconds, and any audio needs at least one image or video alongside it when calling the minimax h3 video model.
Is commercial use of generated clips allowed?
Absolutely. Footage rendered through the fal.ai API with the minimax h3 video model can be used in paid work, subject to fal.ai's terms of service.
