What MiniMax H3 can control

01

Foley cut to the picture

A wok clip where the oil hiss, the garlic crackle, the two flame whooshes and the soy sizzle are generated with the picture, so each sound lands on the action instead of being scored afterwards.

Prompt

16:9, one continuous shot in a small night kitchen, overhead camera looking down at a seasoned carbon steel wok on a gas ring. A ladle of oil hits the hot wok, it shimmers and starts to smoke. A hand tosses in sliced garlic and green beans, the wok is lifted and flipped twice, flames lick up the side. Soy sauce is drizzled in, a burst of steam, the hand sets the wok down and the frame holds. Audio: gas ring hiss, oil crackle rising as the food goes in, the metal scrape of the ladle, two whoosh flares, the sharp sizzle of the soy sauce, then a quiet kitchen fan. No music, no dialogue, no subtitles, no logos.

02

Ambience that moves with the frame

A lighthouse as a storm arrives: gusts peak as the grass flattens, waves build to one heavy impact, and the foghorn closes the clip. Pick 768p or 2K through the quality setting.

Prompt

16:9 single wide shot, a stone lighthouse on a cliff as a storm arrives at dusk. The camera is locked off on the cliff path, the lighthouse in the right third. Low grey clouds move fast, grass bends flat in the gusts, the beam starts to rotate. The first big wave hits the rocks below and throws spray up past the base. Rain sweeps across the frame from left to right and the beam passes through the drops. Audio in stereo: a steady gale with gusts that peak when the grass flattens, waves building to one heavy impact, spray hiss, rain arriving on the left channel first, the lighthouse foghorn once near the end. No music, no voice, no text.

03

Mechanical sound at macro scale

Two dial clicks, the film advance ratchet and one shutter clap on a vintage camera, all placed at close range in an eight second clip. Duration accepts every integer from 5 through 15 seconds.

Prompt

16:9 product clip on a dark oak desk, a single warm lamp from the upper left. A vintage 35mm film camera sits center frame. Macro push-in on the shutter speed dial as a hand turns it two clicks. The hand advances the film lever and presses the shutter; the camera stays sharp, the background falls off to black. The hand sets the camera down and the lens catches one highlight; hold. Audio: two crisp dial clicks, the ratchet of the film advance, one mechanical shutter clap, a soft thump on wood, faint room tone underneath. No music, no dialogue, no brand name, no text.

What you can make with MiniMax H3

2K product hero clip

Animate an approved packshot into a 5 to 15 second 2K product reveal with synchronized impacts, room tone, or handling sounds.

Audio-led performance beat

Use one voice or music file as the only reference and generate a short visual performance whose movement and native sound arrive in the same output.

Mixed-reference character shot

Provide face and wardrobe images, a movement clip, and an audio cue to direct one short scene from a compact reference package.

Sound-ready vertical ad

Produce a 9:16 social cut with the product action and synchronized sound already aligned, ready for review before captions and final branding.

The technology behind MiniMax H3

How the model works, based on public documentation and sourced evidence.

MiniMax officially released H3 on July 31, 2026 as a general omni-modal generation model. The release supports unified understanding of text, image, video, and sound context, then produces video with native stereo audio. Vidney exposes text-to-video, image-to-video, and reference-to-video for integer durations from 5 to 15 seconds.

The model offers 768p and native 2K output through a strict quality parameter. Reference mode accepts up to 9 images, 3 videos, and 3 audio files in a set order, and an audio file can be the only reference input.

MiniMax attributes H3's multimodal instruction handling to Contextual Omni Representation, its compressed latent representation to H3-VAE, and generalized cross-modal generation to H3-Omni Transformer. For 2K output, the company describes In-context Regeneration, where the base model regenerates a higher-resolution result using the original context instead of relying on a separate conventional super-resolution module.

Reference mode is billed on output seconds plus the seconds of reference video you supply, separate from the text-to-video price. MiniMax also acknowledges that some scenes still need finer visual detail, so 2K availability should not be treated as a guarantee that every reference or texture survives unchanged.

Who reaches for MiniMax H3

MiniMax H3 is for creative teams that want a compact video request to return a high-detail clip with sound already synchronized to the picture. It supports text-to-video, image-to-video, and omni-reference generation, with native 768p or 2K output and integer durations from 5 to 15 seconds. The reference mode can combine up to 9 images, 3 videos, and 3 audio files, including an audio file as the only reference, which suits a short performance, product beat, or character moment driven by a sound cue. Choose H3 when native 2K, synchronized audio, and mixed reference media matter more than maximum clip length. Seedance 2.5 is the better fit when the brief needs more than 15 seconds or a much larger source package of up to 30 images, 10 videos, and 10 audio files. Seedance 2.0 or another established model may still be preferable when a production already has approved prompts and settled moderation expectations around it. Do not choose MiniMax H3 when the deliverable must exceed 15 seconds, when native audio and 2K add no value to the brief, or when the reference set exceeds 9 images, 3 videos, or 3 audio files.

What creators say about MiniMax H3

Recurring themes from public reviews, comparisons and creator write-ups. Both the good and the bad.

What gets praised

  • Early users praise reference-to-video for holding character likeness from several reference images, and one workflow author reports that character sheets with close facial views can reduce the need for a separate character LoRA.

  • A separate tester reports that changing reference_image_size from match to max retained face detail much more closely, while keeping source images below roughly 2500 pixels on the long edge avoided the steep slowdown they saw with 4K inputs.

Common complaints

  • Some reference-to-video users report that source images lose detail and pick up visible artifacts, although others in the same discussion say expanded prompts, aspect matching, and workflow settings can change the result.

  • Local open-weight users report heavy compute cost at high resolution, including one 1920 by 1088, 10 second image-to-video run that took 45 minutes on a PRO 6000 GPU. This is a local runtime complaint and is not presented as Vidney API latency.
