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.

Example

Request parameters

Parameter names match our Veo video models, so a single integration works across both.

Check status

On success, outcome.media_urls[0].url is the generated video (720p mp4), with thumbnail_image_url alongside.

Pricing

  • Video output (720p): $0.10 per second of generated video — same rate with or without audio, and independent of aspect ratio.
  • Input references (text/image/video) are billed at $1.50 per 1M tokens (Gemini tokenization).

Capabilities & limits (public preview)

  • Duration: 3-10s (1s increments) or auto; Resolution: 720p; Aspect ratio: auto, 16:9 or 9:16
  • With a video input the output follows the source clip — set durationSeconds to auto (or omit it); an explicit duration that doesn’t match the source is rejected by the model
  • Up to 5 reference images; input video up to 10s
  • Not yet supported: audio references, last-frame guidance, scene extension
