平台透明度说明
LongCat Video 是围绕 LongCat 视频工作流和相关第三方模型搭建的独立工作台。我们不是模型开发者，也未获模型方背书；我们负责的是界面、计费、安全边界、附加工具和支持。
LongCat Video 更适合这些任务
当你的目标不是一闪而过的短片，而是更完整的连续镜头时，LongCat Video 更有发挥空间。
长镜头广告和创意片段
做 30-60 秒以上的广告、宣传或概念片时，更在意人物、服装和灯光别在中途跑偏。
产品演示和解释视频
把一个镜头或一套参考图延长成更完整的解释型片段，不用频繁重开故事。
续写和镜头延展
当你手里已经有一个稳定起点，续写往往比重新生成更重要，LongCat Video 在这一步更值得被拿来试。
LongCat Video 的关键能力
不是所有视频模型都把“长一点也别崩”放在前面，LongCat Video 的卖点恰恰在这里。
13.6B dense 架构
每一帧都尽量保持主体和细节稳定，而不是只在前几秒看起来很强。
coarse-to-fine 渲染
先出草稿，再逐步提清晰度，减少为了一个长镜头整条重跑的代价。
Block Sparse Attention
把算力更集中地用在长片段连续性上，而不是把资源全烧在短时间炫技上。
continuation 训练
延长镜头时更重视人物、镜头和光线不要突然重置。
托管工作台 + 自托管
先用工作台快速试，再按团队需要决定要不要自己托管开源权重。
开放权重灵活度
适合研究、产品和创意团队把同一套长视频工作流接进自己的基础设施里。
为什么团队会在意 LongCat 的连贯性能力
LongCat Video 真正有吸引力的地方，是更适合长一点的镜头：更少跳脸、更少灯光重置、更少故事断裂。
文生、图生、续写一条链路
同一套工作流同时承接提示词起步、参考图起步和 continuation，不用在不同模式之间重搭故事。
更适合长一点的片段
continuation 训练和奖励机制让 LongCat Video 更重视长片段里的主体稳定和动作连续，不只是短时间的视觉冲击。
先保连续性，再谈炫技
真正值钱的是人物别突然变、镜头别突然跳、光线别突然漂，而不是每 5 秒换一个看起来很炸的镜头。
托管和自托管都能走
想快一点就先用托管工作台；想更深控制成本、环境和自动化，就再考虑自托管开源权重。
团队为什么会先试 LongCat Video
长镜头、续写、开放权重和更稳的主体表现，是这条线的核心信号。

3 步跑通 LongCat Video
Prompt 或参考图进来，LongCat Video 出去，中间重点盯连贯性。
1
步骤 1：写清镜头目标
把主体、动作、镜头、节奏和时长说具体。要做续写时，先把起始画面和延展方向想清楚。
2
步骤 2：选文生、图生或续写
新故事从文生起，有稳定起点就从图生或 continuation 起，这样更容易守住画面连续性。
3
步骤 3：审连续性再导出
先看人物、灯光、镜头和动作有没有稳住，再导出 MP4、GIF 或缩略图，而不是只看某一帧炸不炸。
LongCat Video 常见问题
关于长镜头一致性、许可、硬件和 continuation 的直接回答。
不是。LongCat Video 是独立工作台，连接 LongCat 及其他第三方模型。我们负责界面、计费、安全和支持，不是模型开发者。
LongCat AI 一般指 Meituan LongCat 相关模型族。这个站点聚焦的是 LongCat Video 工作流：文生视频、图生视频和 continuation。
支持。continuation 正是 LongCat Video 最值得试的一点：延长镜头时更重视人物、光线和动作的连续性。
这里指的是为什么它更适合长视频一致性：更看重主体稳定、镜头延续、光线连续和 continuation 训练。
因为托管工作台把界面、计费、续写相关工具和支持打包好了，你不用先自己搭完整条链路再验证模型是否适合。
托管生成使用购买的积分，新账户不再自动获赠积分。已有余额按原有效期保留，每次生成前会显示准确费用。
如果你要自己跑长镜头，通常仍建议准备 24GB 以上显存；更轻的测试可以从更低配置开始，但要接受速度和上限上的妥协。
暂时没有公开 API。当前主要通过网页工作台提供；如果你需要自动化接入，建议先自托管开源权重，或联系支持确认集成方案。
