Generate and edit videos with Gemini Omni Flash

Gemini Omni Flash (gemini-omni-flash-preview) is a high-performance multimodal model designed for high-speed video generation, editing, and cinematic control. Gemini Omni is built on the following core capabilities that distinguish it from previous video models:

• Native multimodality: it processes text, image, audio, and video simultaneously, giving you more cohesive, consistent, and controllable output.
• Conversational editing: enabled by the Interactions API, it lets you iteratively refine and edit your videos through natural language conversation. Describe what you want to change, and the model applies the edit while preserving the parts of the video you want to keep.
• World knowledge: Gemini Omni combines an understanding of physics with Gemini's knowledge of history, science, and cultural context, bridging the gap from photorealism to meaningful storytelling.

Text to video generation

Generate a video from a text prompt. The model generates a video with audio based on your text description. Write prompts with details like scene description, camera movement, lighting and mood for best results.

import base64
from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-omni-flash-preview",
    input="A marble rolling fast on a chain reaction style track, continuous smooth shot."
)
with open("marble.mp4", "wb") as f:
    f.write(base64.b64decode(interaction.output_video.data))

import { GoogleGenAI } from '@google/genai';
import * as fs from 'fs';
const ai = new GoogleGenAI({});

const interaction = await ai.interactions.create({  
  model: 'gemini-omni-flash-preview',  
  input: 'A marble rolling fast on a chain reaction style track, continuous smooth shot.',
});

if (interaction.output_video?.data) {
  fs.writeFileSync('marble.mp4', Buffer.from(interaction.output_video.data, 'base64'));
}

}'

REST response schema

The convenience field interaction.output_video is SDK-only. Get the video output from the steps array when using the REST API directly.

Raw REST JSON structure:

{
  "steps": [
    { "type": "user_input", "content": [{"type": "text", "text": "..."}] },
    { "type": "thought", "content": [{"text": "...", "type": "thought"}] },
    {
      "type": "model_output",
      "content": [
        {
          "type": "video",
          "mime_type": "video/mp4",
          "data": "AAAAIGZ0eXBpc29t..." // Base64 encoded video data
        }
      ]
    }
  ],
  "id": "v1_...",
  "status": "completed",
  "model": "gemini-omni-flash-preview",
  "object": "interaction"
}

Control aspect ratio

Set the aspect_ratio to "9:16" to create portrait videos. Landscape (16:9) is the default.
