What is MiniMax H3?
MiniMax H3, also known as Hailuo 03, is MiniMax's video model released in July 2026. It turns a text prompt, a first-frame image or a set of reference images, videos and audio into a clip with native stereo audio, 4 to 30 seconds long at up to 2K. H3Gen runs MiniMax H3 in your browser: no install, no GPU, pay only for the seconds you render.
Why creators pick MiniMax H3
One prompt covers picture, camera and sound, so a draft is close to a finished cut.
Sound comes with the picture
Dialogue, ambience and effects are generated together with the video. There is nothing to sync afterwards: describe the sound in your prompt the way you describe the shot.
Start from a single photo
Upload one image as the first frame and MiniMax H3 animates it, keeping the face, product or layout you started with. The aspect ratio follows your image.
Clips up to 30 seconds
Pick any whole length from 4 to 30 seconds (up to 15 at 2K). That is enough for an ad hook, a title sequence or a full product reveal in one generation.
MiniMax H3 text to video
Describe the subject, the action, the camera move and the sound. MiniMax H3 renders the beats in the order you wrote them, so a shot list reads straight into a prompt. Choose 21:9, 16:9, 4:3, 1:1, 3:4 or 9:16 before you start.
MiniMax H3 image to video
Bring a product shot, a portrait or a frame from your storyboard. MiniMax H3 uses it as the opening frame, or moves between it and an optional last frame, and builds the motion and sound from your prompt, from 4 to 30 seconds.

How to create with MiniMax H3
Four steps from idea to a downloadable MP4.
Name the subject, what happens, how the camera moves and what we hear. Quote any words that should appear on screen.
Who MiniMax H3 is for
Anyone who needs short, sound-ready video from words or a single image.
Product and e-commerce brands
Turn one packshot into motion for a product page, a launch post or a marketplace listing.
Filmmakers and storyboard artists
Block a scene, try a camera move and judge the timing before a shoot or a final render.
Game and 3D artists
Show a character or an environment in motion for a trailer beat or a pitch deck.
Designers and motion editors
Animate posters, title cards and UI mock-ups with legible on-screen text.
Try MiniMax H3
Put the shot, the camera and the sound in one prompt, then change one detail at a time. Try: “A chef in whites sits on a station bench at night, tastes from a bowl, looks up and says ‘It needs salt.’ Slow push-in across the wet platform. Sound: his voice, light rain, a distant train.”

MiniMax H3 capabilities
What each feature does, and what it means for the clip you are making.
Text to video
Describe a scene, a camera move and the sound. The model follows the order of the beats you write.
Image to video
Animate a still from its first frame while the subject, colours and layout stay as they were.
Native stereo audio
Dialogue, effects and ambience are rendered with the picture, so every clip plays back with sound on.
480p to 2K output
Draft at 480p for 4 credits per second or 768p for 6, then render the keeper at 1080p for 8 or 2K for 10, sharp enough for small text and skin detail on a large screen.
Multi-shot clips
Ask for cuts between shots and they happen inside one clip, with the same subject and look.
Readable on-screen text
Quote the exact words you want on a sign, a title card or a package and they come back legible.
Camera direction
Ask for a dolly zoom, a tracking shot, a push-in or a handheld feel, and the move stays on your subject.
Six aspect ratios
Render 21:9, 16:9, 4:3, 1:1, 3:4 or 9:16, so one idea fits cinema, feed and story formats.
Text or image: which to start from
Both run on MiniMax H3 at 2K with sound. What changes is how much you fix in advance.
Exploring an idea: text to video
Start here when the look is still open and you want MiniMax H3 to compose the frame. Clips run 4 to 30 seconds in any of six ratios.
Keeping a look: image to video
Start here when a face, a product or a layout has to stay exactly as it is. Clips run 4 to 30 seconds and follow the image's ratio.
Paying for what you render
Every second of 2K video costs 10 credits: a 5-second clip is 50 credits, a 15-second clip is 150. Failed renders are refunded.
