Gemini Omni 1.2 Flash: 15 second AI video clips, 30% cheaper

Google's new video model makes longer clips, lets you edit them in conversation and costs $0.07 per second at 720p in the Gemini API.

On November 5, 2026, Google DeepMind released Gemini Omni 1.2 Flash, a video generation and editing model that makes clips of up to 15 seconds, up from 10. It lets you change a clip by chatting with it, and its price in the Gemini API drops 30% to $0.07 per second of 720p video.

Key facts

Google announced Gemini Omni 1.2 Flash on November 5, 2026, as the successor to Gemini Omni 1.1. It is generally available in the Gemini API and on Google Cloud.
Clips can last from 3 to 15 seconds, set in one second steps. The previous version stopped at 10 seconds.
The price falls 30%, to $0.07 per second for 720p video. Drafts come out at 360p or 720p and can be upscaled to 1080p or 4K.
The model also reaches Flow, Google Vids, Google Ads and the Gemini app, where 15 second videos are rolling out to Google AI Ultra subscribers.
Every clip carries an invisible SynthID watermark.

What happened

Google published the announcement on its blog on Thursday, November 5, and The Decoder reported the same details that day. Omni 1.2 Flash is a model that both creates and edits video. The headline change is length: a single clip can now run for up to 15 seconds, which is enough for a short ad or a social video without stitching several pieces together.

The second change is editing by conversation. After a clip is made, you can ask the model to swap a product, change the background, the light or the weather, or switch the aspect ratio, and it changes the existing clip instead of starting again from zero. Google says this works across the full 15 seconds.

The company also lists better use of reference material: images of a character, product or style, motion clips of up to 3 seconds and audio cues. It says faces and objects stay more consistent from the first frame to the last, speech and lip sync sound more natural, and camera moves such as orbits, zoom outs and fly throughs are easier to direct. Google adds that fast sports action and complex physics are still being worked on.

Why it matters

Short video is now the main format on most social platforms, and many small businesses cannot film something new every week. Longer clips and cheaper seconds make it more realistic to test an idea, an ad or a product spin with AI before paying for a shoot.

Editing in conversation matters just as much. Until now, changing one detail often meant generating the whole clip again and hoping the rest stayed the same. Being able to say “same scene, evening light” saves time and keeps a series of clips looking alike, which helps when you publish several versions of the same message for different audiences.

There is also a transparency point. Google marks every output with SynthID, an invisible watermark, so the clips can be recognised as AI generated by tools that read it.

How to try it

A 15 second clip is only useful if you know what to post and when. Our free Four week content calendar prompt plans a month of posts for Instagram or TikTok, with format, opening line, idea and call to action, so you can decide which ones are worth turning into AI video. Fill in the fields like this:

Your business or project: “Small bike repair shop in a university town”
Platform: “Instagram”
Main goal: “More local customers”
Posts per week: “3”
Topics to cover and limits: “Quick repair tips, before and after fixes, the spring service offer; no prices, no customer faces”

When the table comes back, pick the reels with the clearest single idea: those are the best candidates for a short generated clip. Check that the plan does not invent numbers, statistics or customer quotes, since the prompt asks it not to. Then describe each chosen reel in one or two sentences with subject, action, setting and light, and keep the same description of the place in every clip so the series looks consistent. Always tell viewers when a video is made with AI if your platform asks for it.
