MiniMax H3 is a browser-based AI video generator that creates short 2K clips with stereo audio from text, image, video, and audio references, offered free on SupaImagine via the independent gateway minimax-h3.net.
What is MiniMax H3?
MiniMax H3 is MiniMax's general-purpose multimodal generation model. This site is an independent browser entry that hands you off to SupaImagine's MiniMax H3 model page to generate text-to-video and image-to-video clips. The tool runs entirely in a modern browser after Google sign-in, with no desktop install, and produces short clips up to about 15 seconds at 2K resolution with native stereo sound.
Key Features
- Multimodal context to video — Combine text, image, video, and audio references in one prompt; the model follows relationships across modalities, not just a single still.
- First & last frame control — Guide the start and end of a clip so motion lands where you want it, useful for product demos and story beats.
- Commercial-grade product motion — Built for ads, branding, and e-commerce with instruction following, text and brand rendering, and controllable motion in the browser.
- Text to video — Prompt-first generation with MiniMax H3 as the default on SupaImagine's model page.
- Image to video — Continue from an uploaded image when your workflow needs a starting frame.
- Free tier, no card — Start with 10 free credits on login, earn up to 30 via weekly check-in; upgrade only when you need more volume.
- History and library — Reopen past runs and re-download outputs instead of hunting local files.
- Independent disclaimer — Not affiliated with MiniMax; model names are used for identification only.
