Why the minimax h3 video model deserves a spot in your workflow
As MiniMax's open-weight omni-modal model, the minimax h3 video model runs on fal.ai and handles text, imagery, moving footage, and sound within one unified context. It delivers up to 15 seconds of 2K video with built-in stereo audio, supports localized edits, crisp text rendering, and accepts as many as 12 reference media files per query.
- A Single Pass for Every MediumIn one request, the minimax h3 video model ingests up to nine images, three video clips, and three audio tracks, blending character, movement, cinematography, and acoustic elements into a seamless final output.
- Stereo Sound by DefaultEach clip from the minimax h3 video model comes with its own music, speech, sound effects, and room tone locked to the visuals, plus voice transfer and cloning based on reference audio.
- Pinpoint Edits to Specific AreasSwap objects, modify on-screen text, replace speech, or shift daylight to darkness — the minimax h3 video model alters just the chosen area while everything else remains unchanged.
