What is Gemini Omni 1.2 Flash Edit?
Gemini Omni 1.2 Flash Edit is an AI video editor built on Google's Gemini Omni 1.2 Flash. You give it one clip of up to 15 seconds and describe the change in plain words. It returns a new version of the same shot, with the same movement, the same camera move, the same framing and the same length. On OpenClips it runs in the app, through the REST API and through the MCP server, and every edited MP4 lands in your library.
Edit a video with words
Most video changes do not need a new shoot or a new render. With Omni 1.2 Flash Edit you can:
- Change the season or the weather: turn a dusk shot into a snowy winter night.
- Change clothes and colours: swap a denim jacket for black leather and keep the person.
- Change the set: move a product from dark stone to white marble and keep the product and its light.
- Make ad variants: keep one hero shot and make versions for different markets, seasons or campaigns.
How the edit keeps your shot
An edit is not a new video. The model reads your clip and changes only what the prompt asks for. Write the change first, then list what must stay the same, such as the people, their faces, the product and the camera move. The result is exactly as long as your source clip, so it drops back into your cut without any retiming.

Prompt guide for video editing
Start with the change in one sentence, such as "Turn this scene into a winter night: snow falls steadily and ice coats the rocks." Then say what stays: "Keep the lighthouse, its beam, the camera move and the framing exactly the same." Add how the sound should change if it matters. One clear change per edit gives the cleanest result.
