Gemini Omni 1.1 Flash is Google's current Omni video model. Over the first Omni it adds a choice of resolution (360p drafts up to 4K), and first-and-last-frame clips. It always makes sound.

## When to use it

- Ads with people, sound and natural-language edits.
- A transition between two images you already have.
- Draft at 360p, which Google says is up to 60% faster, then make the final at 1080p or 4K.

## How to prompt it

- Write timed beats like `[0-2s]` and `[2-6s]`.
- Describe what you want, not what you don't.
- With first and last frames, describe only the change between them.
- References work best for faces and likenesses; a reference video for style or camera alone doesn't work.

[Prompting Gemini Omni](https://sloosh.ai/docs/prompting-gemini-omni.md) has the full guide, including captions, audio and tags.

## Example

First and last frame: the original bottle, and the gold-cap edit made with Seedream 5 Pro. The prompt describes only the change.

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)

->

Input: end frame: ![The same serum bottle with a brushed gold dropper cap](https://sloosh.ai/docs/m-seedream-5-pro.webp)

->

Result: [![The serum bottle's black dropper cap turning to brushed gold](https://sloosh.ai/docs/m-gemini-omni-1-1-flash.webp)](https://sloosh.ai/docs/m-gemini-omni-1-1-flash.mp4) (video)

_9:16, 720p, 5 seconds, Enhance off. Clips here play without sound; press one to pause._

**Prompt**

```text
One continuous shot, locked-off camera. A ripple of warm light sweeps down the serum bottle and the black dropper cap turns to brushed gold, catching a soft glint at the end. The bottle, label and background do not move.

## Frequently asked questions

### How long can a Gemini Omni 1.1 Flash video be?

A single Gemini Omni 1.1 Flash clip is 3 to 10 seconds in Sloosh. To go longer, extend it in 10-second steps up to 40 seconds with the Video edit node's Extend task in Spacelab, or join separate clips with Video Concat.

### Can Gemini Omni 1.1 Flash use a start and end frame?

Yes. Gemini Omni 1.1 Flash takes an optional start frame and an optional end frame, and an end frame needs a start frame. Google's advice is to describe only the transition between the two images, as in "A smooth cinematic transition from a lush green forest at sunrise to a snowy forest".

### Which resolution should I use for Gemini Omni 1.1 Flash?

Draft at 360p, which Google says is up to 60% faster than 720p, then make the final at 1080p or 4K. Google produces the 1080p and 4K versions by upscaling, and 720p is the default in Sloosh.

### Does Gemini Omni 1.1 Flash use the audio from a reference video?

No. Google says any audio in a Gemini Omni video reference is ignored, and that video references work best for likenesses such as a face. Write the sound you want on its own Audio line in the prompt.
