Key Advantages of the minimax h3 video model for Creators
As MiniMax's open-weight omni-modal model, the minimax h3 video model lives on fal.ai from day one. It ingests text, stills, footage, and audio in one pass, then outputs 2K video with built-in stereo sound for up to 15 seconds. You also get targeted editing, sharp text/UI rendering, and as many as 12 reference inputs per run.
- A Single Unified Input SpaceWith support for up to nine images, three clips, and three audio tracks in one request, the minimax h3 video model blends character, motion, camera, and audio into a seamless output.
- Synced Built-in Stereo SoundEach output from the minimax h3 video model includes original music, spoken dialogue, foley, and ambient effects locked to the edit, plus voice transfer and cloning from audio references.
- Region-Specific Video EditingSwap objects, adjust text, redub lines, or shift daylight to night — the minimax h3 video model changes only the chosen area, leaving everything else unchanged.
Steps to Run the minimax h3 video model
Follow three simple steps to generate 2K video with synced audio through the minimax h3 video model API.
Feature Set of the minimax h3 video model
With three dedicated API endpoints, one unified multimodal context, synced sound, targeted edits, crisp on-screen text, and flexible usage-based pricing, the minimax h3 video model gives you a full 2K production workflow on fal.ai.
Three Dedicated Generation Modes
For the minimax h3 video model, you can use text-to-video, image-to-video with optional start/end frame control, and reference-to-video endpoints, covering all creative workflows.
Up to a Dozen Referenced Media Inputs
Mix nine images, three short clips, and three audio files; the minimax h3 video model extracts character identity, motion, camera style, layout, and pacing from those references.
Clean Text and UI Rendering
Produce crisp titles, end screens, captions, and logo reveals, and animate working interfaces — websites, game menus, HUDs, and kinetic type using the minimax h3 video model.
Long Prompts for Full Scene Control
Add an entire shot list to one request; the minimax h3 video model handles prompts as long as 7,000 characters to direct every part of the scene.
2K Output at 24 Frames Per Second
Generate 2K video with a 1440px shorter edge, up to 15 seconds at 24fps, plus six aspect ratio presets and an adaptive option from the minimax h3 video model.
Usage-Based API Pricing
Access the minimax h3 video model on a serverless, pay-as-you-go basis — no minimum commitments, no monthly plans, and commercial rights to the videos you create.
