Longer clips, with a clearer unit price

Google announced Gemini Omni 1.2 Flash on November 5, extending native video generation and editing to 15 seconds, up from 10 seconds in Omni 1.1. Requested durations run from three to 15 seconds in one-second increments.

Google states a price of $0.07 per second for 720p video, describing it as a 30% reduction from Omni 1.1. At that rate, one 15-second generation is $1.05. That arithmetic is not a quote for a finished production with retries, revisions or other services.

A continuing edit is not a proven result

The update lets users revise the same clip through a conversation. Google describes changing details without starting the sequence over and using reference images, short motion clips and audio cues. It also claims better consistency and faster generation; those improvements were not independently tested for this article.

Google acknowledges remaining problems with fast sports action, rapid script changes and complex physics. Its selected demonstrations do not show how often an ordinary brief will need correction.

For anyone assessing generated footage, the relevant unit is a usable sequence after review, not just a successful request. Check the opening and closing frames, but also transitions between them. An object that looks right at either end can still change during the movement.

Availability and provenance are separate questions

Google announces general availability through the Gemini API and Gemini for business. In the Gemini app, 15-second videos are rolling out to Google AI Ultra subscribers. Those are different access routes, not a promise of identical availability in every product.

Outputs carry an imperceptible SynthID watermark, according to Google. DeepMind describes SynthID as embedding a detectable signal in generated content, designed to withstand common modifications such as cropping and compression.

That signal addresses origin: whether content was generated or altered using supported AI systems. It cannot establish that the scene depicts a real event, that a depicted product works, or that its text is accurate. Watermark detection and checking the content itself remain different tasks.
