Good to know
Billing
Runs bill your account credits at provider cost with 0% markup. The submit response includes the credit estimate; failed generations are refunded automatically. Add ?dryRun=1 to get the estimate without running anything.
Errors
Errors are always { "error": { "code", "message" } } with stable codes: unauthorized, model_not_available, invalid_parameter, insufficient_credits, rate_limited. A failed run is not an HTTP error — poll responses report status: "FAILED" with the reason.
What makes Gemini Omni Flash different
Audio is part of the prompt, not a post step
Gemini Omni Flash renders dialogue, music, and sound effects natively, in the same generation as the picture. There is no separate audio pass and no lip-sync fix-up afterwards — you direct the soundtrack the same way you direct the camera: write it into the prompt. A line of spoken dialogue, a mood of music, a door slam, all from one text box.
Any duration from 3 to 10 seconds
Pick any whole-second length from 3 to 10. Pricing depends on the duration you choose, and longer clips can cost less in total: a 10-second 720p clip is $0.50 while a 5-second one is $0.63, because even durations (4, 6, 8, 10 seconds) hit the model's floor rate of $0.05 per second at 720p. When in doubt, generate the longer clip and trim.
Native 720p with 1080p and 4K upscaling
The model generates natively at 720p; 1080p and 4K options upscale that render for delivery. On 10-second clips, 1080p is $0.63 and 4K is $1.05 total. Both landscape 16:9 and vertical 9:16 are supported, so the same prompt can serve a widescreen cut and a story-format cut.
One node in a larger pipeline
On a Scenetra board, Gemini Omni Flash is a node you wire into a workflow: draft prompts with the copilot, generate a clip, then feed it onward — into the family's own Video Edit mode for a text-directed revision, or alongside other video models for comparison. Every run is billed at provider cost with 0% markup, pay-per-generation, no subscription gate.

Frequently asked questions
What is Gemini Omni Flash?+
Gemini Omni Flash is Google's Gemini video generation family. The text-to-video mode turns a prompt into a 3-10 second clip with native audio — dialogue, music, and sound effects generated together with the picture and directed entirely through the prompt. On Scenetra it runs as a node in the visual workflow editor, alongside image-to-video, reference-to-video, and video-edit modes.
Does Gemini Omni Flash generate audio?+
Yes — audio is one of its defining features. Spoken dialogue, background music, and sound effects are rendered natively in the same pass as the video, and you direct all of it through the text prompt. There is no separate audio model, no extra audio fee, and no lip-sync post-processing.
How much does Gemini Omni Flash cost?+
On Scenetra, a 10-second 720p clip costs $0.50 ($0.05 per second) and a 5-second 720p clip $0.63 — per-second pricing varies with the duration you pick, and even durations (4, 6, 8, 10 seconds) get the cheapest rate. On 10-second clips, 1080p is $0.63 and 4K is $1.05. Everything is billed at provider cost with 0% markup.
Why does a 10-second clip cost less than a 5-second one?+
Because the underlying pricing favors certain durations: at 720p, even durations like 4, 6, 8, and 10 seconds run at the $0.05-per-second floor, while a 5-second clip prices higher in total ($0.63 versus $0.50 for 10 seconds). Scenetra always routes each generation to the cheapest capable option and sells at cost, so the practical tip is simply to prefer even durations.
What resolutions does Gemini Omni Flash support?+
The model generates natively at 720p. 1080p and 4K options upscale that native render for delivery — on 10-second clips they cost $0.63 and $1.05 respectively. Aspect ratio can be 16:9 landscape or 9:16 vertical.
Is Gemini Omni Flash free to try?+
Gemini Omni Flash is a paid model. On Scenetra it's pure pay-per-generation from your credit balance — no subscription gate, nothing to cancel.
How should I prompt Gemini Omni Flash?+
Treat the prompt as a director's brief for both picture and sound. Describe the scene, the action, and the camera move — then the audio: put dialogue in quotes, name the music mood, and call out sound effects you want to hear. Because audio is generated natively, a prompt like 'a barista says "one flat white" over soft jazz, steam hissing' produces a clip where all three actually happen.
