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 Video Edit 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 does Gemini Omni Flash video edit do?+
It edits an existing video with a plain-text instruction: upload a clip of up to 10 seconds, describe the change — a new background, a restyled look, a swapped object — and the model regenerates the video with that change applied. The output keeps the source's length, framing, and audio. On Scenetra it runs as a node in the visual workflow editor.
How long can the source video be?+
Up to 10 seconds. The output matches the source's duration and aspect ratio — the model edits the content, not the timing or the frame.
Does the edit keep the original audio?+
Yes — the output preserves the source video's audio along with its length and framing. The edit changes what you describe in the prompt and leaves the rest of the clip intact.
How should I write an edit prompt?+
Keep it simple and specific: name the one change you want, then add "Keep everything else the same." to preserve the rest of the scene. Stacking several changes into one prompt tends to work worse than running two focused edits back to back.
Can I edit videos generated by other models?+
Yes — any video up to 10 seconds works as a source, whether it came from Gemini Omni Flash's own text-to-video mode, another model on your Scenetra board, or an upload from your camera roll. A common pattern is generating with one model and using Video Edit as the revision pass.
