Why Creators Pick the minimax h3 video model
Built by MiniMax and offered on fal.ai from launch day, this open-weight omni-modal engine treats text, stills, clips, and audio as one shared context. A single run returns 2K footage carrying its own stereo soundtrack and can last up to 15 seconds, while accepting as many as 12 reference inputs. Localized editing lets you swap a product, rewrite signage, or shift the time of day without disturbing the rest of the frame.
- Multimodal by DesignA single minimax h3 video model run can absorb up to 9 images, 3 video clips, and 3 audio tracks, weaving identity, performance, camera work, and sound into one coherent result.
- Soundtrack IncludedMusic, dialogue, foley, and ambience arrive already timed to the cut, and a voice can be carried over from a reference recording through transfer or cloning.
- Region-Level EditingSwap a product, rewrite on-screen text, redub a line, or turn midday into midnight — the minimax h3 video model changes only the targeted area and leaves everything else untouched.

What exactly is the minimax h3 video model?
It is MiniMax's open-weight, general-purpose omni-modal generation model, offered on fal.ai as a Day 0 ecosystem partner. A single context absorbs text, images, video, and audio, and each result is 2K footage with original stereo sound lasting up to 15 seconds.
Which endpoints are available?
There are 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 taken from your reference material.
What resolution and length can I get?
The minimax h3 video model returns 2K video (1440px short edge) at 24fps, with clips running 5 to 15 seconds across ratios such as 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16, plus an adaptive mode.
