Inside the minimax h3 video model: Omni-Modal Video Generation
Built by MiniMax and available on fal.ai from launch day, the minimax h3 video model is an open-weight, omni-modal generator. It reads text, pictures, footage, and sound inside one shared context, then renders 2K clips of up to 15 seconds with stereo audio baked in. You also get region-level editing, sharp on-screen text, and as many as 12 reference files per run.
- Every Input Type in One PassA single generation can draw on up to 9 images, 3 video clips, and 3 audio tracks, so identity, performance, camera work, and sound all resolve into one coherent piece of footage.
- Soundtrack Baked Into the RenderEach result carries original music, spoken lines, foley, and ambience already matched to the cut, and voices can be transferred or cloned from reference recordings.
- Surgical Region-Level EditsSwap a product, rewrite signage, redo a line of dialogue, or shift a scene from day to night — only the targeted area changes while everything around it stays put.
Three Steps to Your First Render with the minimax h3 video model
Three quick moves stand between your API key and a finished 2K clip with matched audio.
Capabilities Packed Into the minimax h3 video model
Three endpoints, one shared multimodal context, stereo sound rendered in-frame, region-precise edits, crisp typography, and usage-based billing — that is the toolkit the minimax h3 video model puts in your hands on fal.ai.
Three Ways to Start a Render
Text-to-video, image-to-video with first- and last-frame control, and reference-to-video give you an entry point for nearly any production workflow.
Twelve Reference Slots per Run
Mix 9 stills, 3 video clips, and 3 audio tracks; the engine pulls identity, performance, camera movement, composition, and cutting rhythm out of each one.
Crisp Typography and UI Animation
Type stays sharp in end cards, captions, and brand marks, and real interfaces — landing pages, game menus, HUDs — can be animated with clean, believable motion.
Room for 7,000-Character Briefs
Drop an entire shot list into one request; prompts of up to 7,000 characters keep every beat of the scene under your control.
2K Output at 24fps
Renders land at 2K with a 1440px short edge, running up to 15 seconds at 24fps across six aspect ratios plus an adaptive mode.
Usage-Based Pricing, No Lock-In
Serverless billing means no minimums and no subscriptions, and generated content comes with commercial-use rights.
Frequently Asked Questions About the minimax h3 video model
Straight answers on the minimax h3 video model's inputs, output limits, audio support, and licensing.
What exactly is the minimax h3 video model?
It is MiniMax's open-weight, general-purpose omni-modal generation system, hosted on fal.ai as a Day 0 ecosystem partner. A single model works across text, images, video, and audio within one context, producing 2K footage with stereo audio lasting up to 15 seconds.
Which endpoints can I call?
There are three: text-to-video, image-to-video with optional first- and last-frame control, and reference-to-video, which locks subjects, styles, motion, camera moves, and voices taken from your reference materials.
Which resolutions and clip lengths are available?
Output lands at 2K (1440px short edge) and 24fps, with clips running 5 to 15 seconds. Aspect ratios cover 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16, plus an adaptive option.
Does it produce sound as well as picture?
Yes. Every generation ships with stereo audio — original music, dialogue, foley, and ambience aligned to the edit — and voices can be transferred or cloned from reference recordings.
How many reference files are allowed per generation?
Twelve in total: 9 images, 3 video clips (2–15s each), and 3 audio tracks (2–15s each). Audio needs to be paired with at least one image or video clip.
Am I allowed to use the results commercially?
Yes. Content generated through the fal.ai API can be used in commercial projects, with rights governed by fal.ai's terms of service.
