Gemini Omni 1.2 Flash: 15-Second AI Video Clips at 30% Less, Now Generally Available
Google made Gemini Omni 1.2 Flash generally available on November 5: native 15-second video creation and editing, multi-turn conversational editing, and a 30% price cut to $0.07 a second for 720p video. It is the first time Gemini Omni has been generally available, backed by Google Cloud's infrastructure and security, and it is rolling out across the Gemini API, Google AI Studio, the Google Cloud Console, Flow, Google Vids, the Gemini app and Google Ads.
The headline is simple: longer clips, lower price, real availability. The previous version, Omni 1.1, was a preview with a 10-second ceiling. Version 1.2 raises the ceiling, cuts the price, and turns a preview into a product teams can build on.
What changed from Omni 1.1
Clips now run up to 15 seconds, up from 10, with duration set in one-second steps from 3 to 15. The price drops 30% to $0.07 a second for 720p video, so a full 15-second clip costs about $1.04 to $1.05. One honest note on the old price: Google announced a 30% cut to $0.07, which implies Omni 1.1 sat at about $0.10 a second, but Google did not print the old number in the announcement, so the $0.10 figure is arithmetic, not a quote.
The more useful change is editing. Gemini Omni 1.2 Flash introduces multi-turn conversational editing: fix one detail with a follow-up instruction instead of re-rendering the whole clip. Paired with enhanced reference following, which Google says works across the full 15-second length, the workflow is supposed to cut costs: draft at 360p or 720p, fix the detail that is wrong, then upscale the keeper to 1080p or 4K. Every generated video carries an imperceptible SynthID watermark to indicate its origin.
Where you can use it
For developers, the model is generally available on the Gemini API and Google Cloud, with Provisioned Throughput for production workloads. For everyone else, it is showing up across Google's product line: Flow, Google Vids, the Gemini app and Google Ads. In Google Vids, 15-second clips are available at no additional cost to people with a Google account or a Google Workspace subscription. Access through the Gemini app is rolling out to Google AI Ultra subscribers, so if you are not on Ultra, or the rollout has not reached you, the app will not show it yet.
Google says existing Omni 1.1 calls will route to 1.2 rates from December 3, so teams on the old model ID do not need to migrate by hand. The model ID to use is gemini-omni-1.2-flash.
What Google says it still cannot do well
Google notes that work remains on fast sports action, rapid script changes and complex physics, so those uses may still be challenging. The consistency claims in the announcement are Google's own demos; no third party has published results. That is the normal state of a launch day: the vendor's clips look good, and the only way to know whether the model holds up on your prompts is to test it.
The price comparison
At $0.07 a second, Omni 1.2 Flash undercuts its nearest rival on price. Kling 4.0 Flash, which opened to everyone on November 4, costs $0.094 a second at 720p, but generates clips up to 20 seconds against Omni's 15. The full Kling 4.0 sits at $0.157 a second, with 30-second takes and higher resolutions. The choice is not really about the per-second price. It is about the workflow: Omni 1.2 for conversational editing inside Google's products, Kling for longer takes and heavier reference steering. Both are live now, and both are cheap enough that the cost of finding out is a few dollars, not a budget decision.
What the price cut changes in practice
The arithmetic is what makes the cut matter. A 5-second clip costs $0.35, a 10-second clip $0.70, and a full 15-second clip about $1.05. A hundred 15-second clips costs $105. For a team producing social video, that turns the model from a demo into a line item you can budget: draft at 360p or 720p, fix one detail with a follow-up edit instead of re-rendering, then upscale only the keeper to 1080p or 4K. The editing feature is the real saving, not the headline price, because every re-render you avoid is a full clip you do not pay for.
If you are already on Omni 1.1, the migration is automatic: Google plans to redirect requests to the legacy model ID gemini-omni-1.1-flash to version 1.2 from December 3, at 1.2 rates. If you are choosing between Omni 1.2 and Kling, the deciding question is simple. Do you edit inside Google's products, or do you need longer takes and heavier reference control? Answer that, and the model picks itself.
