CSuite
功能 · 视频

生成片段,剪成一部影片。

根据提示词、一张照片或首帧和尾帧生成单个片段,每个镜头都用你挑选的前沿级模型。然后对片段进行延长、修剪、裁剪和格式转换,或者在多轨时间轴上组装完整视频,由 AI 起草各个场景。云端生成使用你自己的 API 密钥运行,开放模型通过 GGML 运行时在本地渲染,编辑和渲染都在你的电脑上进行。

选择

为每个镜头选对模型。

用 Veo 3.1 拍带同步音频的主视觉镜头,用 Seedance 2.0 Fast 低成本地反复迭代,场景需要不同的风格时就用 Kling 3.0 或 Gen-4.5。每个平台(Runware、OpenRouter 或 Replicate)只需一个 API 密钥,就能解锁它托管的所有模型;Google、Runway 或 Kling 等厂商的密钥可以直连运行该厂商自己的视频模型;自动模式会根据提示词在其中挑选;无论由哪个模型渲染,你的片段、提示词历史和设置都保留在同一个工作区中。
生成

从提示词到成片。

描述镜头(主体、运镜、光线),选择宽高比和分辨率,然后渲染。把模型保持在自动模式,在提示词里写上“8 秒,带音频”,就会为这次运行设置时长和声音。提示词框会在运行过程中依次显示各个阶段(“正在准备输入”“正在生成”“正在下载视频”),在 Replicate 上显示真实的百分比,在 Runware 和 OpenRouter 上显示基于时间的估算,完成的片段会像其他文件一样保存到你的项目文件夹中。这里播放的片段是 CSuite 中 Veo 3.1 真实生成、未经修饰的结果。下方的输入栏里就是所用的原始提示词,同一测试在每个视频模型上的渲染结果都可以在该模型的目录页面上查看。
动画

从静帧开始,以动态收尾。

把一张照片附加为首帧,再描述运动。模型会严格从这张图像开始生成动画,保留你的构图和主体。在同样接受尾帧的模型上,给它第一个和最后一个画面,它就会生成连接两者的运动:非常适合产品旋转展示和场景转场。提示词框会为所选模型接受的每种参考类型显示一行(首帧、尾帧、参考图、源视频),不支持的则显示为灰色。
提示词优化

输入大意,得到镜头指导。

按一下魔杖,一句话就会变成一个完整的镜头描述:主体和动作、运镜、构图、光线和情绪。附有首帧时,它会指导运动,而不是重新描述场景;只有当模型真正渲染音频时,它才会写入声音。视频按秒计费,而且要等好几分钟才能返回,所以含糊的尝试才是代价最高的。
编辑

无需离开应用即可修整片段。

那些通常需要打开剪辑软件的日常剪辑操作,全都内置在应用中,由你电脑上的 ffmpeg 驱动,进度可以随时取消,也不会上传任何内容。

按用途调整大小

把全分辨率的渲染结果缩小到 720p 用于网页嵌入,或缩小到 480p 方便快速分享。从 240p 到 1080p 中选择一个预设高度,宽度会跟随片段的宽高比。

裁剪成新的宽高比

把 16:9 的横向镜头变成适合 Shorts 和 Reels 的 9:16 竖版,或者适合信息流的 1:1 方形。按宽高比裁剪,让动作保持在画面中央。

转换封装格式

把同一个片段交付为 MP4、WebM 或 MOV,无需在其他工具里来回转换:给你的网站一个 WebM,给要求 MOV 的剪辑师一个 MOV。也可以按你想要的帧率和宽度导出循环播放的 GIF。它会出现在你的图像工作区中,可以直接放进 README 或 Slack 讨论串里。
修剪输入入点和出点,或者把播放头停在某处后点击“设置”。保留的范围会以色带形式显示在进度条上。
速度把片段放慢到半速或加快到 2×,任何音频的音调都会保持不变,而不会变得又尖又细。
提取或移除音频把片段的音轨单独提取为 MP3(它会出现在音频工作区中),或者去掉音轨得到无声版本;由于画面不会重新编码,只需几秒钟。
延长镜头AI 菜单中的两个操作可以让片段延续下去:“延长(使用视频)”会把片段交给一个接受源视频的模型,“延长(使用最后一帧)”会把它的最后一帧作为下一个片段的首帧。写好提示词,按下“生成”,只有新生成的画面会被保存。
放大用 Real-ESRGAN 把片段放大到 1080p 或 4K:无需提示词,只需在 AI 菜单中选择即可。它使用你的 Replicate 密钥运行:生成也可以来自 Runware 或 OpenRouter,但放大和移除背景仅支持 Replicate。
移除背景用 BiRefNet 把主体(人物、产品、动物)抠出来,放到绿幕上,或者导出为带真实 Alpha 通道的透明 WebM,在合成中干净地叠加在其他图层之上。
逐帧查看方向键每次把播放头移动一秒;按住 Shift 则每次移动一帧,方便找到精确的剪辑点。播放控制栏上的相机按钮会把那一帧保存为 PNG。
清楚手里的素材一个面板集中显示时长、分辨率、帧率、编解码器和码率;对于 CSuite 生成的内容,还会显示背后的模型和提示词。
合成

不只是片段,还有完整的视频。

合成是面向长视频创作的第二种模式:在多轨时间轴上排布标题、图像、片段和音频,让聊天根据一段描述起草整部剪辑,把任意静帧变成一个镜头,再在本地渲染出一个完整的视频,格式可选 MP4、WebM 或 MOV,最高 4K。时间轴、图层面板和导出的完整介绍,请看合成页面。
目录

可用的模型和提供商。

目录中的所有视频模型,都在同一个模型选择器里。云端模型通过 Runware、OpenRouter 和 Replicate 运行,也可以直连 Google、Runway、Kling 等厂商,全部使用你自己的密钥;开放权重模型通过 GGML 运行时在本地运行。每个模型的详情页上都有真实的示例片段。
