Gemini Omni 1.1 Flash Now Supports Video Extension Up to 40 Seconds

Google's Gemini Omni 1.1 Flash model generates video clips of 10 seconds by default, but a scene-extension feature allows developers to append additional 10-second segments, reaching a maximum total duration of 40 seconds across four segments. The generally available version, released on August 27, 2026, expanded the model's context window to the previous 10 seconds, enabling improved visual consistency and narrative continuity between segments. Extensions work via the Files API, where users upload an existing clip and pass its URI along with a text prompt describing the next scene. Developers can also chain segments using a previous interaction ID, which reduces token usage and better preserves scene state across multiple extension calls. Notable limitations include the inability to insert footage at the beginning or middle of a clip, a 10-second cap on directly uploaded input videos, and restrictions on adding dialogue when extending an uploaded video.
