Kling 3.0 animates a start image you give it, optionally towards an end image. It understands scripted scenes and dialogue, makes sound, and runs from 3 to 15 seconds.

## When to use it

- Bringing a product or lifestyle photo to life with a scripted moment.
- Short scenes with spoken lines.
- When references or several elements matter most, use [Kling V3 Omni](https://sloosh.ai/docs/kling-v3-omni.md).

## How to prompt it

- Treat the start image as an anchor. Describe what happens from it: the action, the camera, what changes. Don't describe the image again.
- One subject action and one camera move per clip, plus what must stay still.
- For longer clips, add timing: "At the 4th second..."
- Dialogue: `Name (tone, language): "line"`. Describe ambient sounds in plain sentences.

## Example

The product photo is the start frame; the prompt adds one action and the sound.

Input: start frame: ![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)

->

Result: [![A hand unscrewing the dropper of the serum bottle and letting a drop fall back in](https://sloosh.ai/docs/m-kling-3-0.webp)](https://sloosh.ai/docs/m-kling-3-0.mp4) (video)

_5 seconds, sound on, Enhance off. Clips here play without sound; press one to pause._

**Prompt**

```text
A hand reaches in and unscrews the black dropper from the amber serum bottle, lifts it and lets one golden drop fall back into the bottle. The camera stays close and still; soft studio light. Sound: a soft glass clink and a quiet drip.
```

## Frequently asked questions

### Kling 3.0 vs Kling V3 Omni: which should I use?

Use Kling 3.0 for prompt-led scripts that start from one photo. Use [Kling V3 Omni](https://sloosh.ai/docs/kling-v3-omni.md) when references or consistency matter: Kling says Omni is the pick when "reference images, video elements, element voice control, or high subject consistency are central". In Sloosh, Kling 3.0 takes no references, while Omni takes 7.

### Do I need a start image for Kling 3.0?

Yes. Kling 3.0 in Sloosh requires a start image and animates from it; an end image is optional. Describe what happens from the image, the action, the camera and what changes, rather than describing the picture again.

### How do I write dialogue for Kling 3.0?

Kling's format for Kling 3.0 dialogue is `Name (tone, language): "line"`, for example `Potter (warm, proud, English): "Every one of these is made by hand."`. Kling lists Chinese, English, Japanese, Korean and Spanish. Describe ambient sounds in plain sentences.

### Can I choose the aspect ratio in Kling 3.0?

No. Kling 3.0 has no aspect ratio setting in Sloosh, only a length setting of 3 to 15 seconds. In the example on this page, a portrait product photo used as the start frame gave a portrait clip, so crop the start image to the shape you want.

### How do I time events in a long Kling 3.0 clip?

Add timing markers to the prompt, such as "At the 4th second, ...", which Kling's own Kling 3.0 guide recommends for longer clips. Keep to one subject action and one camera move, and say what must stay still.
