What the MiniMax H3 Video Model Brings to Your Workflow
MiniMax's open-weight omni-modal system powers the minimax h3 video model, and it runs on fal.ai from day one. Text, stills, footage, and sound share one context, so a single call can return 2K video with built-in stereo audio up to 15 seconds long, region-specific edits, crisp on-screen text, and as many as 12 reference inputs.
- Four Inputs, One Shared ContextA single generation can draw on as many as 9 images, 3 video clips, and 3 audio tracks, letting identity, performance, camera work, and sound resolve into one consistent result.
- Sound Baked Into Every RenderOutputs arrive with original score, spoken lines, foley, and room tone already aligned to the cut, and voices can be transferred or cloned from a reference recording.
- Surgical Edits That Hold the FrameSwap a product, rewrite on-screen signage, redub a line, or shift a scene from day to night — only the targeted area changes while everything else stays steady.
Three Steps to a 2K Clip with the MiniMax H3 Video Model
Go from an API key to finished 2K footage with synchronized audio in three straightforward steps.
MiniMax H3 Video Model: Core Capabilities
Unified multimodal context, three API endpoints, native stereo audio, region-level editing, sharp text rendering, and usage-based pricing — the minimax h3 video model covers a full 2K production pipeline through fal.ai.
Three Endpoints, Every Workflow
Text-to-video, image-to-video with first- and last-frame control, and reference-to-video cover prompt-driven scenes, keyframe animation, and style-locked shots.
Up to 12 Reference Inputs
Feed in 9 images, 3 video clips, and 3 audio tracks; the engine reads identity, performance, camera movement, composition, and cutting rhythm from them.
Sharp Text and UI Rendering
End cards, captions, logos, and animated interfaces — landing pages, game menus, HUDs, and kinetic typography — all render cleanly instead of turning to mush.
7,000-Character Prompts
Fit an entire shot list into one request; prompts of up to 7,000 characters give full-scene control over pacing, framing, and detail.
2K Output at 24fps
Video comes back with a 1440px short edge, runs up to 15 seconds at 24fps, and supports six aspect ratios plus an adaptive mode.
Usage-Based API Pricing
Serverless billing with no minimums and no subscription, plus commercial rights over the content you generate.
MiniMax H3 Video Model: Frequently Asked Questions
Straight answers about what this MiniMax H3 model can do, how billing works, and how to call it on fal.ai.
What is this MiniMax H3 model?
It is MiniMax's open-weight, general-purpose omni-modal generation system, offered on fal.ai as a Day 0 ecosystem partner. A single model reads text, images, video, and audio together and returns 2K footage with native stereo audio of up to 15 seconds.
Which endpoints are available?
Three: text-to-video, image-to-video with optional first- and last-frame control, and reference-to-video, which locks in subjects, styles, motion, camera moves, and voices from the material you supply.
What resolution, frame rate, and length can I expect?
Output is 2K with a 1440px short edge at 24fps, running 5 to 15 seconds, in 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16, plus an adaptive option that follows your source.
Is audio generated along with the video?
Yes. Each render ships with stereo audio — original music, dialogue, foley, and ambience timed to the cut — and voice transfer or cloning is supported from reference recordings.
How many reference files can I attach?
Twelve in total: 9 images, 3 video clips of 2-15 seconds, and 3 audio tracks of 2-15 seconds. Any audio you attach must be paired with at least one image or video.
Can I use the results commercially?
Yes. Content produced through the fal.ai API is cleared for commercial projects, subject to fal.ai's terms of service.
