Meet the minimax h3 video model
Built by MiniMax and launched on fal.ai as a Day 0 ecosystem partner, the minimax h3 video model is an open-weight omni-modal engine. A single context absorbs prompts, pictures, footage, and sound, then returns 2K video carrying native stereo tracks of up to 15 seconds. Targeted region edits, crisp on-screen typography, and as many as 12 reference files per run come standard.
- All Inputs, One Shared ContextFeed it as many as 9 stills, 3 clips, and 3 audio tracks at once; the minimax h3 video model weaves identity, acting, camera work, and sound into one consistent output.
- Sound Arrives Already SyncedMusic, spoken lines, foley, and room ambience all come back matched to the cut, and you can carry over or clone a voice from a reference recording.
- Edit One Region, Keep the RestSwap a product, redraw a sign, re-voice a line, or flip daylight to night — only the chosen area changes while the surrounding frame holds steady.
Three Steps to Your First minimax h3 video model Clip
Connect to the minimax h3 video model through fal.ai and ship a 2K clip with matched audio in three quick moves.
What the minimax h3 video model Delivers
From three fal.ai endpoints and a shared multimodal context to stereo sound, region-level edits, sharp typography, and usage-based billing — this engine covers an entire 2K production flow.
Three Endpoints, One Engine
Text-to-video, image-to-video with first and last frame control, and reference-to-video are all exposed, so any workflow has a matching route.
Twelve Reference Slots
Mix 9 stills with 3 clips and 3 audio tracks; the model pulls identity, acting, camera movement, framing, and cutting pace out of those references.
Legible Text and Real Interfaces
Captions, end cards, logos, and on-screen copy stay sharp, and actual UI — landing pages, game menus, HUDs, kinetic type — can be animated inside the frame.
Long-Form Prompt Support
Draft an entire shot list and send it as one request: prompts run as long as 7,000 characters, giving scene-by-scene command.
2K Output at 24fps
Clips land at 2K with a 1440px short edge and 24fps, running as long as 15 seconds across six aspect ratios or an adaptive frame.
Usage-Based Pricing
Serverless billing means you pay only for what you render — no minimum spend, no subscription, and commercial rights attached to the finished content.
minimax h3 video model: Questions Answered
Straight answers about what the minimax h3 video model can do, how it is billed, and where its limits sit.
So what exactly is the minimax h3 video model?
An open-weight, omni-modal engine from MiniMax, served on fal.ai from day one of the partnership. Prompts, stills, footage, and audio all enter the same context, and the output is 2K video with stereo sound lasting no more than 15 seconds.
Which endpoints can I call?
Three are available: text-to-video, image-to-video with optional first and last frame control, and reference-to-video, which pins down subjects, styles, motion, camera moves, and voices taken from the material you supply.
What resolutions and clip lengths are supported?
Renders arrive at 2K — a 1440px short edge — at 24fps, in clips of 5 to 15 seconds. Frame shapes include 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16, plus an adaptive option.
Is audio generated as well?
It does. Music, dialogue, foley, and ambient layers come back in stereo and already lined up with the cut, and voices can be transferred or cloned from a reference track.
How many reference files are allowed?
Twelve at most — 9 images, 3 video clips of 2 to 15 seconds, and 3 audio tracks of the same length. Any audio you add has to travel with at least one image or clip.
Are commercial rights included?
Yes. Anything you produce through the fal.ai API can be used in commercial work, governed by fal.ai's terms of service.
