MiniMax H3 AI Video Generator — No Sign-Up, Sound Included

MiniMax H3 AI Video Generator is a browser-based front end for the MiniMax H3 video model. You type a line, upload a photo or drop in a reference clip and get a finished 4–15 second MP4 that already contains dialogue, sound effects and music.

Audio is produced in the same forward pass as the image rather than added later, delivered as 32 kHz stereo with stable dialogue generation available in 11 languages. Outputs come at 768P or 2K, rendered at 24 fps and offered in six aspect ratios.

• In-browser generation from text, image or reference clip
• Synced audio and scene produced together, 32 kHz stereo
• Stable dialogue across 11 languages; 768P or 2K output at 24 fps

The 2K option isn’t a simple upscale — the model reprocesses the 768P result with your original context to preserve small on-screen text. Free to start with no account, email or card required. Official site: https://minimax-h3ai.video/
