MiniMax H3 video generator: 4 to 15 second clips up to 2K

About MiniMax H3 video generator

minimax-h3.com is a web app for generating video with the MiniMax H3 and H3 Max models. You can start from a text prompt of up to 4,000 characters, from a first frame with an optional last frame to control where the clip ends, or from multimodal references: up to nine images, three video clips and three audio clips, with the videos and audio each capped at 15 seconds in total. Clips run from 4 to 15 seconds at 768p or 2K.

The extra tools are aimed at people who want more control than a single prompt. Lip Sync matches mouth movement to an audio track, Reference to Video builds a clip from visual references, and Recast replaces a person in an existing video. There is a prompt guide, a ComfyUI guide, and comparison pages against H3 Max, Seedance 2.0, Wan 3.0 and Kling 3.0.

Pricing is one-time credit packs with no subscription, and the credits never expire. The pricing page lists four packs, from Starter at about 370 credits (up to five 5-second 2K videos) to Business at 5,550 credits (up to 79), and it was showing a timed 30 percent discount, with Starter at $9.90 instead of $14 and Business at $99.90 instead of $143. Larger packs add faster generation and priority support.

Commercial use is allowed subject to its terms and media rights. Recast in particular should only be used on footage of people who have agreed to it.
