Gemini Omni Flash API Usage Guide

​
Overview

Gemini Omni Flash generates 720p video from a text prompt, optionally guided by reference images and/or an input video. It produces 24 FPS video at durations of 3-10 seconds (1-second increments) in 16:9 or 9:16. All generated videos are marked with invisible SynthID watermarking and C2PA content credentials.
