What is Gemini Omni 1.2 Flash Extend?
Gemini Omni 1.2 Flash Extend is an AI video extender built on Google's Gemini Omni 1.2 Flash. You give it one clip and say what happens next. It adds 3 to 10 seconds to the end that carry on the scene, the camera move and the sound, and returns your clip plus the new seconds as one MP4. On OpenClips it runs in the app, through the REST API and through the MCP server, and every longer clip lands in your library.
Make a video longer with AI
A clip that ends too early does not need a new render. With Omni 1.2 Flash Extend you can:
- Add an ending: let the camera fly on to a reveal, such as clouds parting on a full moon.
- Let a moment play out: give people a few more seconds to turn, smile or walk away.
- Grow a clip step by step: extend a 10 second clip to 15 seconds, then again up to 30.
- Introduce something new: bring a person or a product into the scene with a reference image.
How the extension joins your clip
Omni reads the last 10 seconds of your clip and continues from its final frame, so the motion, the light and the sound carry on across the join. Google may adjust the last few frames of your clip to make the join seamless. The new seconds always go at the end; Omni cannot add a new start or fill the middle of a clip.

Prompt guide for extending a video
Open with "Continue the scene:" and describe the next action, such as "the camera keeps flying past the lighthouse and out over the open sea, and the clouds part to show a full moon." Add the camera move and say how the sound continues. If a person or object left the frame more than 10 seconds before the end, name it again or attach it as an image.
