Inside the minimax h3 video model: One Engine for Every Input
Built by MiniMax and served on fal.ai from day one, the minimax h3 video model is an open-weight, omni-modal engine. It reads text, pictures, footage and sound inside a single context, then renders 2K clips with original stereo audio lasting up to 15 seconds. Localized edits, crisp on-screen text and as many as 12 reference files are all supported.
- All Inputs, One Unified ContextIn a single run, the minimax h3 video model can take 9 images, 3 clips and 3 audio tracks, keeping identity, performance, camera work and sound aligned in one result.
- Sound Baked In, Not Bolted OnOutputs from the minimax h3 video model carry original score, spoken lines, foley and room tone that match the cut, and voices can be transferred or cloned from reference recordings.
- Edit One Region, Keep the RestSwap a product, rewrite a sign, redub a line or shift day into night — the minimax h3 video model touches only the area you target, leaving everything else in the frame untouched.

Straight answers to the questions creators ask most about the minimax h3 video model on fal.ai.
What exactly is the minimax h3 video model?
An open-weight, omni-modal generator from MiniMax, offered on fal.ai from launch day. A single context absorbs text, imagery, footage and sound, and the result is a 2K clip with original stereo audio running up to 15 seconds.
Which endpoints can I call?
Three: text-to-video, image-to-video with optional first and last frame control, and reference-to-video, which carries subjects, styles, motion, camera moves and voices over from your reference files using the minimax h3 video model.
