What You Gain From the minimax h3 video model
The minimax h3 video model is MiniMax's open-weight omni-modal generation system, hosted on fal.ai from day one. It processes text, images, video, and audio together, produces 2K clips with matching stereo audio (up to 15s), and supports targeted edits, clear text/UI rendering, and up to 12 reference inputs per run.
- Unified Multimodal InputA single call can take up to 9 images, 3 video clips, and 3 audio tracks, letting the minimax h3 video model merge identity, performance, camera style, and sound into one seamless result.
- Stereo Audio on Every OutputEach output includes original music, dialogue, foley, and ambience perfectly timed to the action, plus voice transfer and cloning from reference recordings.
- Focused Scene EditingSwap a product, rewrite signage, replace dialog, or turn day into night — the model changes only the selected region while everything else remains locked.
