Google Gemini Omni 1.1 Flash Image To Video API Documentation
Playground
Try it on WaveSpeedAI!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
| Parameter | Required | Description |
|---|---|---|
image | Yes | Start-frame image URL. |
end_image | No | Optional end-frame image URL for interpolation. |
prompt | Yes | Motion, camera, transition, style, and audio instructions. |
aspect_ratio | No | 16:9 or 9:16. Default: 16:9. |
resolution | No | 360p, 720p, 1080p, or 4k. Default: 720p. |
duration | No | 3–10 seconds. Default: 8 seconds. |
Pricing
| Resolution | Price per second |
|---|---|
| 360p | $0.042 |
| 720p | $0.14 |
| 1080p | $0.21 |
| 4K | $0.42 |
Billing is based on generated duration and the selected resolution.
