What Makes the MiniMax H3 Video Model Different
Built by MiniMax and launched day one on fal.ai, the minimax h3 video model is an open-weight engine that treats language, pictures, motion, and sound as one shared context. It renders 2K footage with original stereo audio, clips running as long as 15 seconds, region-targeted edits, crisp on-screen text, and as many as 12 reference files per run.
- A Single Context for Every InputFeed the minimax h3 video model as many as nine pictures, three clips, and three audio tracks at once. Character identity, acting, camera language, and sound design all resolve together instead of being stitched afterward.
- Sound Generated, Not Layered OnMusic, spoken lines, foley, and room tone arrive already matched to the cut. The minimax h3 video model can also borrow or clone a voice from a reference recording you supply.
- Surgical Edits, Stable FrameSwap a product, restyle a sign, redub a line, or shift daylight into night. Only the area you mark changes — everything around it in the minimax h3 video model output holds steady.
Calling the MiniMax H3 Video Model API in Three Steps
Three short steps take you from an empty script to a finished 2K clip with matched audio from the minimax h3 video model.
Capabilities of the MiniMax H3 Video Model
From three separate endpoints to a shared multimodal context, from original stereo sound to region-level retouching, from crisp typography to usage-based billing — the minimax h3 video model covers the whole 2K production path on fal.ai.
Three Ways to Start a Generation
Begin from a written prompt, from a still with optional first- and last-frame anchors, or from reference material. Whichever route you take, the minimax h3 video model fits the way you already work.
Twelve Slots for Reference Material
Stack nine stills, three clips, and three audio tracks together. The minimax h3 video model pulls faces, gestures, camera motion, framing, and cutting pace straight out of whatever you hand it.
Legible Text and Real Interfaces
Captions, end cards, logos, and headline type come out sharp rather than smeared. The minimax h3 video model also animates genuine UI — web pages, game menus, HUD overlays, and kinetic lettering.
Room for a Full Shot List
A prompt can run to 7,000 characters, so an entire scene breakdown fits in one call. That gives you granular direction over the minimax h3 video model without splitting the job apart.
2K Frames at 24fps
Finished clips carry a 1440-pixel short edge, run as long as 15 seconds, and play at 24fps. Choose from six frame shapes or let adaptive mode decide what suits the minimax h3 video model output.
Usage-Based, No Subscription
Billing is serverless and metered, so you pay only for what you render. There is no floor commitment, no monthly plan, and the minimax h3 video model output carries commercial-use rights.
MiniMax H3 Video Model: Frequently Asked Questions
Straight answers to the questions people ask most about running the minimax h3 video model through fal.ai.
What exactly is the minimax h3 video model?
It is an open-weight, general-purpose engine from MiniMax that fal.ai hosts as a day-one ecosystem partner. Rather than chaining separate tools, it keeps language, stills, motion, and sound inside one shared context and emits 2K footage with original stereo audio lasting up to 15 seconds.
Which endpoints can I call?
Three are available: text-to-video, image-to-video with optional first- and last-frame guidance, and reference-to-video, which pins down subjects, visual style, movement, camera behavior, and voices taken from the material you upload.
What output sizes and lengths can I get?
Expect 2K output with a 1440-pixel short edge at 24fps, and clip lengths from 5 up to 15 seconds. Frame shapes include 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16, plus an adaptive option that follows your input.
Is audio produced along with the video?
It does. Each run ships stereo audio generated in the same pass — score, spoken lines, foley, and background atmosphere that line up with the cut. Voices can also be transferred or cloned from a recording you provide.
How much reference material can I attach?
Twelve files in total — nine stills, three video clips of 2 to 15 seconds, and three audio tracks of the same length range. Note that any audio you add has to travel with at least one image or clip.
Am I allowed to use the results commercially?
You can. Anything produced through the fal.ai API is cleared for commercial work, subject to the usage terms fal.ai sets out in its terms of service.
