Gemini Omni 1.1 Flash Image to Video animates a start image, optionally targets an end frame, and generates synchronized audio at resolutions from 360p to 4K. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Animate a start frame into a video with synchronized audio. Supply an optional final frame to generate a continuous transition between two keyframes—useful for smooth camera moves, reveals, or seamless looping concepts.

Why Choose This?

  • First-and-last-frame control — Guide both ends of the shot instead of relying on a start image alone.
  • Continuous transitions — Prompt complex camera orbits, zooms, whip-pans, and scene transformations without intentional jump cuts.
  • Draft-to-production workflow — Explore cheaply at 360p, then deliver in 1080p or 4K.
  • Synchronized audio — Generate sound together with the animated scene.

Parameters

ParameterRequiredDescription
imageYesStart-frame image URL.
end_imageNoOptional end-frame image URL for interpolation.
promptYesMotion, camera, transition, style, 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$0.042
720p$0.14
1080p$0.21
4K$0.42

Billing is based on generated duration and the selected resolution.
