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/text-to-video on POST /jobs/createTask, from $0.138.

Introduction

Gemini Omni 1.2 Flash text-to-video starts with a written idea. Give the place, the action and what should be heard, then choose 3–15 whole seconds. An unset duration produces an 8-second scene. Use 16:9 for a landscape composition or 9:16 for a vertical one.

This route suits an idea that has no starting picture. In our tests, a rainy market prompt produced a cook tossing noodles and saying the requested line, with sizzling oil and background chatter. Google says Omni may build a short story across several shots unless you request a continuous take.

Key features

• Generate the visual scene and its sound together from a required text prompt.
• Set duration in whole seconds, including short 3-second drafts and scenes up to 15 seconds.
• Choose direct 360p or 720p, or request 1080p/4K upscaling by Google at a higher rate.
• Receive 24 fps MP4 video containing an AAC audio track.
• Describe spoken lines, music or environmental effects within the same prompt.

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

• Plan a food-stall vignette with a short line of dialogue and cooking sounds.
• Create a vertical rainy-street scene for a social post without preparing a still.
• Explore a lantern-lit market concept in 360p before selecting a delivery size.

Prompt guide & pro tips

• Establish a specific setting first, such as “a lantern-lit market after rain,” so the action has a clear location.
• Give the subject one readable task, such as “the cook tosses noodles,” before adding another event.
• For an uninterrupted view, follow Google’s guidance and add “in a single continuous shot.”
• Quote a short spoken line, such as “Ready in a minute,” and describe surrounding sound separately.
• For a scene without speech, use Google’s suggested wording “No dialogue”; there is no separate negative-prompt field.
