What is MiniMax H3?

    MiniMax H3 is a video model from MiniMax, the company behind Hailuo. Cinemagiq runs it in two versions: MiniMax H3, driven by a prompt and optional first and last frames, and MiniMax H3 References, which builds the shot from up to 9 reference images. Its standout in Cinemagiq is resolution: you can render at 768p or ask for sharp 2K and 4K upscales of the same shot.

    Write a prompt for text-to-video, or add a first frame, a last frame or both to anchor the shot. With a first frame, the picture follows that frame. MiniMax H3 References takes up to 9 photographic references and offers ratios from 21:9 to 9:16 or adaptive. Clips run 5 to 15 seconds, and sound is always on, so describe what we should hear in the prompt.

    Pick MiniMax H3 when the shot is headed for a big screen and you want 2K or 4K output, such as establishing shots, landscapes and texture-rich close-ups. Since sound is always on, it also suits shots where ambience matters. For faster turnaround and tighter prompt adherence at up to 1080p, use MiniMax H3 Max. If your references are drawings or line art, choose another model.

    • In MiniMax H3 References, use clean, well-lit photos of the subject, not sketches or line art.
    • Test the shot at 768p, then pick 2K or 4K for the take you keep.
