Gemini Omni 1.1 Flash Text to Video creates short AI videos with synchronized audio from text prompts at resolutions from 360p to 4K. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Turn a prompt into a polished video with synchronized audio and stronger creative control. Gemini Omni 1.1 Flash supports a fast 360p draft workflow for prompt exploration, standard 720p generation, and production-ready 1080p or 4K delivery.

Why Choose This?

  • Fast creative iteration — Use 360p previews to test scenes, camera direction, and prompt variations quickly and economically.
  • Professional delivery — Move the chosen concept to 1080p or crisp 4K output.
  • Audiovisual generation — Create motion and synchronized sound together from one prompt.
  • Directable results — Describe framing, camera movement, scene progression, dialogue, music, and ambience in natural language.

Parameters

ParameterRequiredDescription
promptYesScene, motion, camera, style, dialogue, and audio instructions.
aspect_ratioNo16:9 or 9:16. Default: 16:9.
resolutionNo360p, 720p, 1080p, or 4k. Default: 720p.
durationNo3–10 seconds. Default: 8 seconds.

Pricing

ResolutionPrice per second
360p$0.039
720p$0.13
1080p$0.195
4K$0.39

Billing is based on generated duration and the selected resolution. Start at 360p for drafts, then render the selected direction at a higher resolution.
