A Multimodal Studio Inside One MiniMax H3 Video Model
Built by MiniMax and served on fal.ai from day one, the MiniMax H3 video model is an open-weight system that reads text, stills, footage, and sound together. It produces 2K clips up to 15 seconds long with stereo audio, handles pinpoint local edits, renders crisp on-screen text, and accepts as many as 12 multimodal references per run.
- All Inputs Share a Single ContextA single run of the minimax h3 video model can mix 9 images, 3 video clips, and 3 audio tracks, so identity, performance, camera work, and sound stay locked together in one coherent output.
- Stereo Sound Baked Into Every RenderOutputs from the minimax h3 video model arrive with original score, spoken lines, foley, and ambience already aligned to the cut, and voices can be transferred or cloned from reference recordings.
- Edit One Region, Leave the Rest UntouchedSwap a product, rewrite a sign, redub a line, or shift a scene from day to night — the minimax h3 video model changes only the targeted area while the rest of the frame holds steady.
