What does MiniMax H3 Max Text to Video generate?

It creates a video clip from a written prompt, rendering scene details, subject action, camera direction, and visual style at up to 1080p resolution.

What resolutions and durations are supported?

Resolution can be 480p, 768p, or 1080p, and duration can be any value from 5 to 15 seconds.

What is prompt_expansion_mode?

It controls how much the model rewrites your prompt before generation. `disabled` uses your prompt as-is, `balanced` applies light rewriting, and `quality` applies the most thorough rewrite at the cost of extra processing time.

How do I retrieve the finished video?

Poll the request ID returned by the initial POST at `/predictions/{request_id}/result`, or pass a `webhook_url` to be notified when the video is ready.

Which aspect ratios can I use?

21:9, 16:9, 4:3, 1:1, 3:4, and 9:16 are all supported, so you can target widescreen, square, or vertical placements.

Does higher resolution cost more?

Yes. Cost scales with both resolution and duration — 1080p output costs more per second than 768p or 480p.

About MiniMax H3 Max Text to Video API

MiniMax H3 Max Text to Video turns a detailed written prompt into a video clip at up to 1080p resolution. It supports 5-15 second durations, six aspect ratios, and an optional prompt-expansion step that rewrites your prompt for stronger cinematic detail before rendering. The model is built for scenes that need accurate camera movement, lighting, and subject action described purely in text, and it slots directly into Muapi's standard asynchronous request/poll/webhook workflow like every other Muapi video model. For image-guided motion instead of a pure text prompt, see [MiniMax H3 Max Image to Video](/playground/minimax-h3-max-image-to-video); for combining multiple reference assets, see [MiniMax H3 Max Reference to Video](/playground/minimax-h3-max-reference-to-video).
