MiniMax H3

MiniMax H3, also called Hailuo 03, is MiniMax's video generation model. On Plot Party it takes up to 9 reference images and 3 reference audio clips together with a prompt and generates a 1 to 15 second video with sound in one pass, including lip-synced dialogue and several shots with scripted cut times. You run it in the Plot Party generator or Canvas, or through the API.

Yes. MiniMax H3 is the model's official name and Hailuo 03 is the name it carries in the Hailuo app. They are one model.

Up to 9 images and 3 audio clips per generation. Images can be people, animals, products, places or style frames. Audio can be a voice you want a character to speak in, a piece of music to play under the scene, or a sound to reuse. Name each reference in the prompt in the order you uploaded it and say what it is for.

Three things, depending on what you ask for in the prompt. A recording of a voice makes a character speak in that timbre and delivery. A music clip plays under the scene, in full or in part. A sound can be reused as an effect. You can also state how closely to follow each clip: copy it outright, copy part of it, or reference only its character.

Yes. Write the lines in your prompt and the character speaks them, lips matched to the words, in the language you wrote. Speech is supported in 11 languages: Arabic, Chinese, English, French, German, Italian, Japanese, Korean, Portuguese, Russian and Spanish. Give each speaker a stable tag and their voice stays the same across every shot.

Dialogue is written inside the shot description next to the action it belongs to. Ambience and physical sounds such as wheels, wind and footsteps go in a separate soundscape line. Music that only the audience hears goes in a third line, described by instruments and tempo or taken from a reference clip, or left as none. Keeping them apart is what stops sound effects from landing on top of a spoken line.

Any length from 1 to 15 seconds. Output is 480p or 768p, in landscape or portrait. If you need a single shot longer than 15 seconds or 1080p output, Seedance 2.5 on Plot Party generates up to 30 seconds in one take.

Yes. Describe each shot in order and give every shot after the first a cut time, for example at 00:06.000. Framing, camera moves and dialogue are written per shot, and the soundscape runs continuously across the cuts. Cut only when the new shot brings new information; for a closer view of the same subject, use a camera move instead.

Upload one clear reference image per character, product and place, and name it in the prompt. One full-body image per character works better than several crops. You can also mark how much of each reference must survive: kept fully, kept in part, or borrowed only loosely for style. The model holds the references across every shot in the generation.

The H3 base model is released as open weights under the MiniMax H3 Community License. On Plot Party you use it without hosting anything.

In Plot Points per generation. The rate depends on the clip length and resolution you choose, and current rates and plans are on the pricing page.

No. Prompts that mention well-known intellectual property are blocked before generation. Use your own characters, products and reference images instead.
