What is MiniMax H3 Max?
MiniMax H3 Max is a speed-focused AI video generator built for fast iteration on short-form video ideas. It turns text prompts into video, or animates a supplied first frame, with an optional last frame to steer where the scene ends up. Clips run from 5 to 15 seconds and render at either 480P or 768P, making it a practical tool for testing concepts before committing to heavier production work.
Who it's for
- Prompt testers and AI tinkerers — who want to iterate quickly through many variations without waiting on slow renders.
- Social video creators — who need short landscape, square, portrait, or ultra-wide clips for concepting and drafts.
- Product and motion designers — who want quick motion drafts or macro-style product shots before full production.
Key features
Generate Videos from Text
Describe the subject, action, setting, style, and camera direction, and MiniMax H3 Max builds a new video from that prompt. A non-empty prompt is required for every generation.
Animate a First Frame
Upload a starting image and describe the motion you want, guiding how the generated video begins. This is useful for animating an existing still or controlling the opening shot.
Add an Optional Last Frame
After uploading the required first frame, you can add an optional ending image to guide the final visual state. That gives you control over both how a scene starts and where it lands.
Generate in 480P or 768P
Choose 480P for lightweight drafts or 768P for higher-resolution output. MiniMax H3 Max does not support 2K — that resolution belongs to the standard MiniMax H3 workflow.
What stands out
Fast iteration, output at 480P or 768P as you like.
That combination of speed and flexible resolution is the core appeal. You can draft at 480P, then step up to 768P when a concept earns it, without changing tools. Pricing follows the same logic — 6 credits per second at 480P and 9 credits per second at 768P — so lighter drafts cost less. Duration is selectable in whole seconds from 5 to 15, and text-to-video supports landscape, square, portrait, and ultra-wide aspect ratios, while image-to-video follows the uploaded frame.
Worth checking out if…
You want to move fast through video ideas rather than chase maximum resolution. MiniMax H3 Max fits prompt testing, social video concepts, and product motion drafts especially well. If you need 2K output or multimodal reference control with images, video, and audio, the standard MiniMax H3 workflow is the better match — H3 Max deliberately trades those capabilities for speed.
