Input Schema

3 parameters · 1 required · 2 optional

Parameter	Type	Required	Description
`prompt`	string	Required	The text prompt describing the video you want to generate. · Max length: 20000
`duration`	integer	Optional	The duration of the generated video, in seconds. · Min: 3 · Max: 10 · Default: 8
`aspect_ratio`	string	Optional	The aspect ratio of the generated image. · Options: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16 21:916:93:24:35:41:14:53:42:39:16

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

API README

Gemini Omni Flash

google/gemini-omni-flash creates a new video from written scene direction, jointly reasoning about visuals, motion, camera behavior, dialogue, ambience, and sound. Gemini Omni Flash combines multimodal understanding with video generation, supporting coherent scenes, real-world physical behavior, character continuity, and synchronized audio in one creative process. This combination makes the model a practical choice when the creative outcome depends on those qualities rather than on a generic media conversion.

For production work, the text-to-video workflow is intended for rapid conversational iteration, allowing the creative brief to refine action, composition, sound, and narrative intent instead of rebuilding the asset through separate tools. The result is most reliable when the source material and creative brief clearly describe the intended subject, progression, visual or sonic character, and the qualities that must remain unchanged.

Highlights

Prompt-built video scenes. Converts written direction into a complete moving shot without requiring a starting image, making the base route useful for storyboards and motion concepts that begin as language.

Cinematic action interpretation. Resolves subjects, setting, action, atmosphere, and camera intent together so the generated sequence follows a unified creative brief.

Native temporal construction. Builds motion and scene progression across the clip rather than applying a simple animated effect to a supplied still.

Fast concept exploration. The Flash-oriented model supports rapid comparison of different shot ideas before teams commit to a more expensive finishing workflow.

When to Use

✅ Good fit	❌ Consider alternatives
The model's named workflow matches the source material and intended output	A different input modality or model route is required
A managed asynchronous result is suitable for the production pipeline	A synchronous, interactive editor is essential
The documented controls cover the required duration, framing, or format	The project needs controls outside this endpoint's schema
Creative iteration benefits from a repeatable request structure	Exact deterministic pixels, frames, geometry, or samples are mandatory
A finished downloadable media asset is the desired deliverable	Editable source layers or a native project file are required

Prompt Guide

For generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
