Playground

Gemini Omni 1.1 Flash Image-to-Video animates a start image into short AI videos, optionally targeting an end frame and generating synchronized audio at resolutions from 360P to 4K for social content, creative storytelling, marketing videos, and production workflows. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Gemini Omni 1.1 Flash Image-to-Video animates a start image into a video with synchronized audio. You can optionally add a final frame to guide the ending of the shot, making it useful for controlled transitions, reveal sequences, camera movement, and other prompt-guided image-to-video workflows.

Why Choose This?

• Start-frame image animation
  Turn a single image into a video with motion, scene progression, and synchronized audio.

• Optional end-frame guidance
  Add last_image when you want more control over how the shot ends.

• Smooth transition generation
  Useful for camera moves, reveal shots, visual transformations, and controlled motion between two keyframes.

• Draft-to-production workflow
  Use 360p for quick testing, then move to 1080p or 4k for higher-quality output.

• Synchronized audio
  Generate motion and matching audio together in one workflow.

• Flexible output formats
  Supports both 16:9 and 9:16 for landscape and vertical video creation.

Parameters

How to Use

1. Upload the start image — Provide the image that should define the first frame.
2. Add an end image optional — Use last_image when you want to guide the final frame or overall transition direction.
3. Write your prompt — Describe the motion, camera movement, transition behavior, scene changes, style, and audio.
4. Choose aspect ratio — Use 16:9 for landscape video or 9:16 for vertical content.
5. Select resolution — Use 360p for drafts, 720p for standard output, or 1080p / 4k for higher-quality results.
6. Set duration — Choose a duration from 3 to 10 seconds.
7. Submit — Generate the final video with synchronized audio.

Pricing

Pricing is based on generated video duration and selected resolution.

Example Costs

Best Use Cases

• Image animation — Turn still images into short motion clips with audio.
• Controlled transitions — Use image and last_image to guide the beginning and end of a shot.
• Reveal and transformation scenes — Create visual change between two defined states.
• Social media content — Generate vertical or landscape motion content from static artwork or product images.
• Creative prototyping — Quickly test motion, pacing, and shot progression from a single keyframe.
• Marketing and campaign assets — Animate posters, product visuals, and branded images into short videos.

Pro Tips

• Use a clear, high-quality start image for better subject consistency.
• Add last_image when the final pose, composition, or scene state matters.
• Describe both what moves and how it moves in the prompt.
• Include camera instructions such as push-in, orbit, pan, or pull-back for more controlled results.
• Mention ambience, music, dialogue, or sound effects directly when audio guidance matters.
• Start with 360p for fast iteration, then move to 1080p or 4k for final output.
• Use shorter durations for quick tests and longer durations when the transition needs more time to develop.
