# MiniMax H3

> MiniMax H3 video generation with text, first-and-last-frame, and multimodal reference workflows up to 2K.

MiniMax H3 supports text-to-video, image-to-video, and reference-to-video generation in one asynchronous API.

It accepts first and last frames, reference images, reference video, and reference audio, with 4-15 second output at 768P or 2K.

GENGEN validates incompatible image-to-video and reference-to-video inputs before sending a request to MiniMax.
