About Gemini Omni 1.2 Flash

Gemini Omni 1.2 Flash is Google's video model with sound. It makes 3 to 15 second clips from text, a first frame with an optional last frame, or up to six reference images and three reference videos, and it can edit a clip you already have. Sizes run from 360p to 4K.

Call it with the model name google/gemini-omni-1.2-flash/image-to-video on POST /jobs/createTask, from $0.138.

Introduction

Gemini Omni 1.2 Flash image-to-video turns an opening still into movement. Supply image_url and a prompt explaining the action after that image. The pier example uses a nighttime boat still to begin a 5-second departure with engine and water sounds.

Add last_image_url when the scene needs a planned ending. With that closing image, the allowed length is 3–10 seconds; without it, choose 3–15 seconds. In our tests, two studio pictures guided a dancer between the opening and closing poses.

Key features

• Use your supplied still as the first frame of the animation.
• Guide the final composition with an optional second image.
• Generate sound during animation instead of uploading an audio track.
• Select landscape 16:9 or vertical 9:16 for the requested scene.
• Work at 360p or default 720p, with higher-rate 1080p and 4K upscaled by Google.

Request parameters

Pricing

Prices are in USD. The API uses a separate USD balance. Website credits cannot be used or transferred to it, and API funds cannot be transferred to website credits. When a task is accepted, we reserve the maximum quoted amount from your API balance. On completion, we charge for actual usage, never more than the hold, and release the remainder. If the task fails, the hold is released.

Send the same request body to POST /jobs/quote to see the estimated and maximum USD charge before running. A quote does not run the task or charge your balance.

Use cases

• Set a wooden boat departing from a hotel pier in motion from a nighttime still.
• Connect two studio poses over a 5-second sequence with soft piano.
• Turn a product still into a short motion study with a planned final composition.

Prompt guide & pro tips

• Describe what changes after the opening, such as “the boat eases away from the pier,” rather than repeating every visible detail.
• With two images, explain the transition, such as “move smoothly into the closing pose,” and select no more than 10 seconds.
• Specify a restrained camera plan, such as “a locked camera,” when movement within the scene should carry the shot.
• Name the desired ambience, such as “low engine hum and lapping water,” because the still does not supply sound.
• Ask for continuity with a short phrase such as “no scene cuts,” following Google’s advice for a single take.
