Gemini Omni 1.2 Flash drops to $0.07 a second at 720p

The change aimed most directly at advertisers is editing. Follow-up prompts now rework a generated clip along its full length, changing the aspect ratio, the backdrop or the product in shot, and Google pitches that as ad variants with no new brief. Reference images are meant to stop brand colours, pack lettering, clothes and faces drifting when the camera angle changes. Those are Google’s claims. It also says fast sports action and complex physics still need work.

The rollout covers Google Ads, which Google’s post ties to video campaigns, plus Flow, Google Vids, AI Studio, the Gemini API and the Gemini app for AI Ultra subscribers (The Decoder). SynthID, Google’s invisible watermark, sits inside each clip.

On our price sheet, checked 6 November, Veo 3.1 Fast costs $0.10 a second at 720p and Veo 3.1 Lite $0.05. Kling 3.0 was $0.126 with native audio and $0.084 without at our 31 October check. Google’s Flow limits a Veo clip to 8 seconds. A 15-second Omni clip comes to $1.05 at the new rate.

That puts Omni 30% under Veo Fast and 44% under Kling’s audio rate, and of these prices only Veo Lite stays cheaper per second, with about half the clip length in Flow.
