Google's Gemini Omni 1.2 Flash makes video clips up to 15 seconds long, lets you edit a clip in conversation, and costs 30% less in the API.

Google released the model on Thursday and made it "generally available across the Gemini API and Gemini for business" (Google). Clips can now run from 3 to 15 seconds, in one-second steps, "up from 10 seconds with Omni 1.1." You can also change the same clip turn by turn, "such as swapping a product or background, changing the lighting or weather, or switching the aspect ratio," instead of starting over. Google says the model sticks closer to reference images, has more natural speech and lip-sync, and makes fewer unwanted jump cuts during long camera moves. Those are Google's own claims. Google's API pricing page works out to about $0.07 per second of 720p video, or roughly $1.04 for a 15-second clip, down from about $0.10 a second for Omni 1.1. Rough 360p drafts cost about $0.023 a second. There's no free API tier for it, and from Dec. 3, requests to Omni 1.1 will automatically go to 1.2 and be billed at its rates. In Google's apps, Omni 1.2 Flash "is rolling out starting today to all Google AI subscribers," but making 15-second videos in the Gemini app is limited to Google AI Ultra subscribers (Gemini on X). Google Vids makes 15-second clips "at no additional cost in Google Vids with a Google account or Google Workspace subscription." Every clip carries Google's invisible SynthID watermark.

What to weigh: for Shorts and short ads, one 15-second clip can now replace two 10-second ones stitched together, and fixing a detail with an edit is cheaper than making the clip again. Google says it's still working on "fast sports action, rapid script changes and complex physics," so try a few of your own scenes before you pay for a batch.
