Create 4–15 second AI-generated videos with synced dialogue, sound, and 2K resolution easily.
minimax-h3ai.video is an independent, browser-based interface for MiniMax H3 — the video model MiniMax also ships as Hailuo 3. You type a line, upload a photo, or drop in a reference clip, and you get back a finished 4-to-15-second MP4 with the dialogue, sound effects and music already inside it. Sound is generated in the same forward pass as the picture, not dubbed on afterwards, at 32 kHz stereo with stable dialogue in 11 languages.
Output is 768P or 2K at 24 fps, in six aspect ratios. The 2K path is not an upscale: H3 sends the 768P result back through itself with your original context and generates it again, which is why small on-screen text survives.
