What Resolution Does MiniMax H3 Support?

Overview

MiniMax H3’s primary resolution is 2K — roughly a 1440-pixel short edge — generated at 24 frames per second, with a 768p tier reported to be in closed beta. So through the current API, 2K is the headline output you can rely on today. Source note: Verified 2026-08-06 against the MiniMax official H3 blog, MiniMax Video Generation API docs, and Hugging Face MiniMax-H3 model page.

Resolution is worth treating as a deliberate choice per clip rather than a default. Generating everything at 2K is an easy way to inflate a bill, since much content — social drafts, internal reviews, quick concept tests — does not need it. A common workflow iterates at a lower resolution while refining the prompt and composition, then produces the final approved shot at the resolution the channel actually requires.

Because H3 is currently API-only, this resolution runs on MiniMax’s infrastructure; there is no local generation to compare yet, since the open weights have not shipped. Whether a future local build reaches 2K will depend on the released model and your GPU.

Match resolution to where the content lands — mobile-first social rarely needs what a large-screen hero video does — and confirm the current supported tiers on the provider page, since they can change as the model matures out of beta.
