Google Gemini Omni 1.1 Flash Reference To Video API Documentation
Playground
Try it on WaveSpeedAI!Gemini Omni 1.1 Flash Reference-to-Video creates short AI videos with synchronized audio from a text prompt plus optional image and video references, supporting resolutions from 360P to 4K for character-consistent clips, visual reference guidance, social content, marketing videos, and production workflows. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.
Features
Gemini Omni 1.1 Flash Reference-to-Video generates synchronized audio and video from a prompt plus reference media. Use reference images for subject, character, product, or environment guidance, and add short reference videos when motion, camera behavior, or scene rhythm matters.
Why Choose This?
-
Multimodal reference guidance
Combine reference images and short reference videos to guide the final result. -
Character and context consistency
Preserve recognizable subjects, visual identity, and scene context while generating a new video. -
Motion and camera guidance
Use reference videos to communicate gestures, action, pacing, or camera movement that may be difficult to describe with text alone. -
Synchronized audio
Generate video and matching audio together in one workflow. -
Draft-to-production workflow
Start with360pfor faster testing, then move to1080por4kfor higher-quality delivery. -
Flexible output formats
Supports both16:9and9:16for landscape and vertical video creation.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Describe the desired scene and explain how the references should be used. |
| images | No | Up to 10 reference image URLs. |
| reference_videos | No | Up to 3 reference video URLs. Each reference video must be no longer than 3 seconds. |
| aspect_ratio | No | Output aspect ratio: 16:9 or 9:16. Default: 16:9. |
| resolution | No | Output resolution: 360p, 720p, 1080p, or 4k. Default: 720p. |
| duration | No | Video duration in seconds. Range: 3–10. Default: 8. |
How to Use
- Add reference media — Upload reference images, reference videos, or both.
- Write your prompt — Describe the target scene, action, camera behavior, and the role of each reference.
- Choose aspect ratio — Use
16:9for landscape video or9:16for vertical content. - Select resolution — Use
360pfor quick testing,720pfor standard output, or1080p/4kfor higher-quality delivery. - Set duration — Choose a duration from
3to10seconds. - Submit — Generate the final video with synchronized audio.
Pricing
Pricing is based on generated video duration and selected resolution.
| Resolution | Price per second |
|---|---|
| 360p | $0.03 |
| 720p | $0.10 |
| 1080p | $0.15 |
| 4k | $0.30 |
Example Costs
| Resolution | 5s | 8s | 10s |
|---|---|---|---|
| 360p | $0.15 | $0.24 | $0.30 |
| 720p | $0.50 | $0.80 | $1.00 |
| 1080p | $0.75 | $1.20 | $1.50 |
| 4k | $1.50 | $2.40 | $3.00 |
Best Use Cases
- Reference-guided video generation — Create videos that follow specific people, products, objects, or environments.
- Character-consistent scenes — Keep visual identity more stable across generated shots.
- Motion transfer and camera guidance — Use reference videos for action, gesture, pacing, or shot behavior.
- Marketing and social content — Combine brand visuals, products, and motion references into short-form videos.
- Creative prototyping — Quickly test prompt-plus-reference workflows before final production.
Pro Tips
- Use clear, relevant reference images when identity or appearance matters.
- Use reference videos when motion, pacing, or camera behavior is important.
- In the prompt, clearly describe what each reference should influence.
- Avoid mixing too many conflicting references in one request.
- Start at
360pfor iteration, then re-run at a higher resolution for final output. - Keep reference videos short and focused on the motion you want to guide.
Notes
promptis required.- At least one reference input should be provided through
imagesorreference_videos. imagessupports up to 10 inputs.reference_videossupports up to 3 inputs, and each video must be at most 3 seconds.- The model generates synchronized audio together with the video.
