What is MiniMax Hailuo H3 Text to Video?

MiniMax Hailuo H3 Text to Video turns a single text prompt into a cinematic clip, rendering native 2K video at a film-standard 24fps with synchronized stereo audio in one pass. It is the text-to-video mode of MiniMax H3 (also searched as Hailuo 3.0 or Hailuo 03), the third generation in the Hailuo line after Hailuo 01 and Hailuo 02. Where earlier models were specialized short-form generators, H3 is a general-purpose, omni-modal system that reads text, images, video, and audio as one unified context. On Segmind you drive it with a plain prompt: describe the scene, subject, and motion, pick an aspect ratio and a duration from 4 to 15 seconds, and receive an MP4 video directly in the API response.

Key Features

• •Native 2K resolution at 24fps, no separate upscale pass.
• •Clip lengths from 4 to 15 seconds in whole-second increments.
• •Aspect ratios from 21:9 and 16:9 down to 1:1, 3:4, and 9:16 vertical.
• •Synchronized dialogue, sound effects, and ambient audio generated with the picture.
• •Strong instruction following and accurate on-screen text and brand presentation.
• •Simple synchronous API: POST a prompt, save the returned MP4.

Best Use Cases

H3 is built for commercial production. Use it for short ads and product showcases where a clip has to hold up on a large display, for social-first vertical hooks on Reels, TikTok, and Shorts, and for cinematic trailer comps and title sequences. Its instruction following and legible typography make it a fit for brand films, UI/UX motion, and game promos. The 15-second ceiling leaves room for an open, product moment, and close inside one generation.

Prompt Tips and Output Quality

H3 does what you tell it and only what you tell it, so write like a director. Combine a camera move, subject, action, scene, lighting, and mood in a single narrative sentence rather than a comma-separated tag list. Name explicit camera language such as dolly forward, tracking shot, or slow orbit. Longer clips give the model more time to drift, so add continuity cues for 12 to 15 second takes.

How to Use MiniMax Hailuo H3 Text to Video

MiniMax Hailuo H3 Text to Video generates a native 2K clip with synchronized audio from a single prompt. To get consistent, usable takes, treat the prompt like a shot brief and match the aspect ratio and duration to where the video will run.

Write the prompt like a director

H3 follows instructions literally, so give it a clear blueprint instead of a keyword list. A reliable order is camera shot and motion, then subject and description, then action, then scene, lighting, and mood, expressed as one flowing sentence. Name the camera move explicitly, for example dolly forward, tracking shot, or slow orbit, because H3 will not invent one for you. Use strong, specific verbs and adverbs to drive motion, and add temporal cues to sequence events across the clip.

Choose aspect ratio and duration

Set the aspect ratio up front. Use 16:9 for widescreen and YouTube, 9:16 for Reels, TikTok, and Shorts, and 21:9 for cinematic layouts. Duration runs from 4 to 15 seconds and cost scales per second, so start at the default 6 seconds while you iterate on the prompt, then extend to 10 to 15 seconds for multi-beat storytelling. Longer takes give the model more time to drift a face or lose an object, so add continuity constraints for the longest clips.

Recommended settings

• •Prompt: one detailed, narrative sentence covering camera, subject, action, scene, lighting, and mood.
• •Aspect ratio: 16:9 for landscape, 9:16 for vertical social, 21:9 for cinematic.
• •Duration: 6 seconds for quick tests and single moments; 10 to 15 seconds for narrative sequences.
• •Resolution: 2K, the only tier available, delivered at 24fps.

Iterate efficiently

Lock the composition first at a short duration, confirm the camera and subject read correctly, then lengthen the clip and refine lighting and mood. Keep a working prompt and change one variable at a time so you can tell which edit improved the take.

Is MiniMax H3 the same as Hailuo 3.0?

Yes. MiniMax H3 is the official name; Hailuo 3.0 and Hailuo 03 are the widely used community names for the same video model.

Is H3 the same as MiniMax M3?

No. M3 is MiniMax's text and agentic LLM, while H3 is the video-generation model. They were unveiled together but do different jobs.

What resolution and frame rate does it output?

Native 2K at a fixed 24fps, the same cadence as film and broadcast.

How long can a clip be?

From 4 to 15 seconds per generation, in whole-second steps.

Does it generate audio?

Yes. Dialogue, sound effects, and ambience are produced in the same pass as the video and timed to the on-screen action.

Which aspect ratio should I choose?

Use 16:9 for widescreen, 9:16 for vertical social video, and 21:9 for cinematic layouts.
