MiniMax H3 Reference makes H3 video from your references: a product, a person, a setting or a style. References and start or end frames can't be mixed; this option is the references one.

## When to use it

- Putting a real product into a new scene and keeping it accurate.
- Combining a product and a setting from separate images.

## How to prompt it

- Name each file by type and order: "Image 1", "Image 2".
- Give every file a job and say how much to keep: "keep its shape and label exactly", or "use its light and layout only". A file with no stated job is the most common reason a result goes wrong.
- Write camera moves in plain English with size and speed: "The camera pushes in with small amplitude at slow speed." One move per continuous shot.
- Say "one continuous shot, no cuts" for a single take; otherwise "then" can turn into a cut.
- Keep sound, music and speech apart: "Sound: ...", "Music: ...". Put spoken lines in quotes with the speaker, language and tone. Every clip has sound.
- Write constraints as plain sentences; there's no negative prompt. Stay under about 7,000 characters.

## Example

Two references with stated jobs: the product to keep exactly, and the setting to take light and layout from.

Input: product photo: ![An amber glass serum bottle with a black dropper and a cream label reading SERUM 01, on a light grey background](https://sloosh.ai/docs/in-bottle.webp)

->

Input: setting: ![An empty white marble bathroom counter by a window with sheer curtains and a small fern](https://sloosh.ai/docs/in-counter.webp)

->

Result: [![The serum bottle on the marble counter in moving morning light, the camera arcing to the label](https://sloosh.ai/docs/m-minimax-h3-reference.webp)](https://sloosh.ai/docs/m-minimax-h3-reference.mp4) (video)

**Prompt**

```text
Image 1 is the product: an amber glass serum bottle with a black dropper and a cream "SERUM 01" label. Keep its shape and label exactly. Image 2 is the setting: a white marble bathroom counter by a window. Use its light and layout only.
One continuous shot: the bottle stands on the counter from Image 2 as morning sunlight moves slowly across it. The camera arcs to the left with small amplitude at slow speed, ending on a close-up of the label.
Sound: soft room tone and distant birdsong. Music: a slow, sparse piano melody.
```

## Frequently asked questions

### MiniMax H3 Reference vs MiniMax H3: when should I use references instead of frames?

Use MiniMax H3 Reference to put a real product or person into a new scene, where the model is free to choose the framing. Use [MiniMax H3](https://sloosh.ai/docs/minimax-h3.md) with a start and end frame when you need the clip to open and close on exact images. MiniMax doesn't allow both in one run.

### How many reference images does MiniMax H3 Reference take?

MiniMax H3 Reference takes up to 9 reference images in Sloosh. Name each one by order in the prompt, "Image 1", "Image 2", and give every image a job, such as the product to keep exactly or the setting to take light from.

### Why does MiniMax H3 Reference ignore or mix up my reference?

The most common cause is a reference with no stated job. Say what each image is for and how much to keep: "keep its shape and label exactly", "loosely", "only the colour" or "only the mood". Those four levels match MiniMax's own reference guide.

### Can MiniMax H3 Reference make 4K video in Sloosh?

Yes. MiniMax H3 Reference offers 480p, 768p, 2K and 4K in Sloosh, and starts at 2K.
