MiniMax H3 makes 2K video from a long brief

MiniMax's H3 video model — 768p or 2K output and the longest prompt field in LazyKiwi.

MiniMax H3 is the highest-resolution video model in the LazyKiwi workbench: it renders at 2K, where most of the lineup stops at 1080p. It also takes the longest prompt of any model here — 7,000 characters, enough for a full shot list plus a negative-prompt block — and runs all three generation modes: text-to-video, image-to-video and start-and-end-frame transitions. Clips run 4 to 15 seconds across six aspect ratios from 21:9 to 9:16. Specs: up to 768p or 2K.
