MiniMaxH3.app

MiniMaxH3.app is an independent third-party studio and research case library built around MiniMax H3, MiniMax's multimodal video model. It is not the official MiniMax or Hailuo AI product, and the site states this clearly.

The studio is organized around three workflows that are live today. Text-to-video accepts natural-language prompts up to 7,000 characters for subjects, camera moves, lighting, mood, dialogue, and sound effects across six aspect ratios: 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. First/Last Frame animates one or two ordered still images into motion, with output following the source image ratio. This makes it practical for product photography, character key art, concept frames, and lookbook images. Omni Reference is the multimodal workflow: creators can combine up to 9 images, 3 videos, and 3 audio clips to guide subject identity, visual style, motion, pacing, and sound.

Every generation produces native 1440p/2K video at 24 FPS with synchronized stereo audio generated in the same pass as the picture. Speech, sound effects, and environmental ambience are timed to the visible action. Available clip durations range from 4 to 15 seconds.

Beyond generation, MiniMaxH3.app maintains a public showcase of real cases. Each example includes the prompt, reference inputs, generated video, and source context. The site also publishes practical guides covering model capabilities, prompting techniques, workflow selection, and bounded comparisons with other video-generation approaches. Creators can study a real example before choosing a workflow and running their own generation.

Generation is credit-based at 20 credits per output second, so a 5-second 2K clip reserves 100 credits. Failed tasks automatically return the reserved credits. New accounts receive 100 one-time signup credits, enough for one 5-second 2K generation; this is a limited signup grant, not a permanent free plan.

A $19 one-time Starter Pack and monthly or annual subscriptions from $39 per month are available through Stripe. Annual plans are billed once per year and grant credits monthly.

MiniMaxH3.app is designed for creators, filmmakers, marketers, product teams, and researchers who want controllable MiniMax H3 workflows in one browser-based workspace. For official MiniMax applications, APIs, model weights, licensing, or policy information, users should rely on MiniMax's own channels.
