MiniMax H3 Video Generator
Turn a written prompt or a photo into a short AI video clip in your browser.
MiniMax H3 Video Generator (h3minimax.com) is a web app that turns a written prompt or a photo into a short AI video clip. It gives you a simple browser interface to the MiniMax H3 video model: you describe a shot or upload a frame, choose a few documented settings, and the service submits the task, tracks its progress and plays the finished clip right in the page.
With text-to-video, you describe the subject, setting, motion, camera and mood in a prompt of up to 7,000 characters, and H3 generates a clip in one of six aspect ratios: 21:9, 16:9, 4:3, 1:1, 3:4 or 9:16. With image-to-video, you upload a first frame, a last frame, or both, and H3 animates the moment in between.
Every clip can be any whole-number length from 4 to 15 seconds, rendered at 768P for quick drafts or 2K for final cuts. New accounts get free trial credits with no card required, and monthly credit plans are available for regular use.
