无缝延长任意视频片段
上传短视频片段,AI 即可延长。延展引擎分析末帧,生成无缝衔接的新画面。5 秒片段需要 15 秒?工具可追加延续动作、镜头运动与原片整体氛围的新帧。适用于 AI 生成片段与实拍素材。原片与延展部分的过渡足够平滑,多数观众难以察觉分界。
用提示词引导延展方向
可选填写提示词,告诉延展工具接下来发生什么。无提示词时延续现有运动;有提示词时可改变场景走向。例如某人沿街道行走的片段:无提示词则继续行走;加入「人物停下并抬头望天」,AI 会在片段中途改变动作。视频延展不仅用于加长,还可从单一起点构建多镜头序列。
核心能力
为什么选择我们的视频延展?
多数 AI 视频生成器只输出固定时长片段。视频延展让你持续加长,从任意起点构建更长序列。
无缝延续
延展 AI 匹配原片色彩、光影与运动,原片与新画面之间无突兀跳变。
提示词引导方向
添加提示词引导后续情节,或让 AI 根据片段现有运动自行延续。
适用任意来源
可延展 AI 生成片段、录屏、手机视频或专业素材,工具适配各类输入。
链式多次延展
延展一次后再对结果继续延展,从短短片段构建 30 秒以上序列。
1080p 高清支持
延展输出分辨率与输入一致,最高 1080p。
注册即送免费积分
注册即用免费积分测试视频延展,在购买更多积分前验证延续效果。
如何延展视频片段
上传视频
上传要延长的视频片段,MP4 格式最佳。AI 分析末帧以理解后续内容。
添加提示词(可选)
描述延展部分应发生的事。若希望 AI 自然延续现有运动,可跳过此步。
生成并下载
生成视频延展并预览,下载 MP4。可链式多次延展以获得更长序列。
