Gemini Omni 1.2 Flash extends video to 15 seconds and cuts price by 30%

Google has made Gemini Omni 1.2 Flash generally available through the Gemini API and Google Cloud. The release extends native clips from 10 to 15 seconds, lowers 720p generation to $0.07 per second and lets creators revise the same shot through multiple conversational turns.

Fifteen seconds at $0.07 per second targets high-volume ad production

Gemini Omni 1.2 Flash can generate and edit clips up to 15 seconds long. Google cut the price of 720p output by 30% compared with version 1.1. At the base rate, a 15-second clip costs $1.05 before other workflow steps are included.

The model accepts text, images, short video and audio references. A user can create a quick draft at 360p or 720p, select the useful version and then upscale it to 1080p or 4K. Outputs include an imperceptible SynthID watermark.

Conversational editing saves the cost of discarded generations

The more practical change is multi-turn editing. A creator can replace a product or background, change lighting, weather or aspect ratio and keep working on the same clip instead of describing and generating the whole shot again. Google also claims better consistency for faces, clothing, packaging and brand colors across shots.

For marketing teams, that can reduce the cost of producing variants. One scene can serve several formats or audiences, while expensive high-resolution output is reserved for selected versions. The real saving therefore depends on more than the per-second price. It depends on how many failed generations and manual repairs the workflow avoids.

Complex motion and physics still puncture the polished demo

The model card acknowledges continuing problems with complete consistency across edits, complex motion and perfectly accurate text. Google also says work continues on fast sports action, rapid script changes and complex physics. Better reference adherence is a vendor claim, not a guarantee for every clip.

Availability has caveats too. The model is generally available through the Gemini API and Google Cloud, but audio references in the cloud offering require allowlisting. A production team must verify the particular feature and region it needs, rather than relying only on the model name in a catalog.

Acceptance rate will reveal the true cost of each usable clip

The key metric is not generated seconds but the share of outputs accepted without a full restart. If multi-turn editing preserves the person, product and text while changing one requested detail, the 30% price cut can translate into faster campaign production.

Teams should also track upscaling costs, rejected attempts and access to audio references. The $0.07 per-second rate describes 720p generation. The bill for a usable advertisement includes every attempt, edit, review and final render.

Lilith's verdict

Google cut the price of film by the second, but producers mostly pay for shots that land in the bin. If Omni 1.2 keeps the face and product intact after the third edit, the price list will finally resemble real production.
