MiniMax H3 bills per second of generated video, with two resolution tiers: 768P and 2K. Understanding the relationship between resolution, duration and cost makes it easy to plan a full production budget.
The 768P tier is the iteration workhorse. It renders faster and bills at a lower per-second rate, which makes it ideal for prompt testing, style exploration and social-first content where 768P is already the delivery resolution.
The 2K tier is priced higher per second but delivers the detail H3 is built for — fine textures, clean edges and stable faces at full-screen scale. Reserve 2K for final renders: once your prompt, subject and camera language are locked from 768P tests, a single 2K pass gives you the deliverable.
Duration multiplies everything. H3 clips are billed strictly by output length, so trimming a scene from 10 seconds to 6 seconds cuts the cost proportionally. Storyboard before generating: know exactly how long each shot needs to be.
A concrete budgeting pattern for a 30-second product video: generate five candidate shots at 768P with short durations, pick the best two, then re-render those two at 2K with full duration. You get cinema-quality finals while spending most of your budget only on shots you will actually use.
The MiniMax H3 generator shows a live cost estimate that updates with every resolution and duration change, so you can see the exact price of a shot before generating it.
