Video Extend: Gemini Omni 1.1 Flash
通过Gemini Omni 1.1 Flash，每步可将现有视频延长最多10秒，总时长可达40秒。模型会分析最后10秒的上下文，在场景从上次结束处继续时保持角色、动作和音频连贯。可选附加参考图像，在故事中途引入新角色。适用于上传的剪辑和之前已生成的视频；用自然语言描述场景应如何继续。非常适合更长的叙事、场景分支和迭代式故事创作。

A tumbleweed rolls past in the background. The dramatic western score dissolves into a warm honky-tonk piano. Keep the same characters and live-action style consistent. Extend by 5 seconds.",
