先给大家看一段视频，你们觉得拍这么一段得花多少钱多长时间？ 如果我说，这根本不是实拍，而是AI在几分钟内"一键生成"的，你敢信吗？ 春节前，当大家还在忙着抢红包的时候，字节跳动毫无征兆地扔出了一颗"王炸"——新一代视 频生成模型Seedance 2.0。 AI生成视频不是什么新鲜事，但过去可能得花不菲的价钱，反复生成几十次，才能赌到一个勉 强能用的片段。但Seedance 2.0不一样，它号称"一条过"， 一次生成的视频可用率据说能达到 惊人的90%。 光能看还不够，它还能把你的想法，直接变成"导演级"的叙事，知道什么时候该特写，什么时 候该拉远，还能让不同镜头里的主角保持一致。影视飓风的Tim在体验后都抑制不住兴奋地表 示，模型在摄像机运动、分镜连续性以及音画匹配上都非常出色。 这意味着什么？这意味着，导演、摄影师、剪辑师、配乐师……这个传统影视工业链条，正在 被一个模型"打包压缩"。有专业摄影人士分析，如果 人工制作一段十几秒打斗视频，涉及CG 制作、动作捕捉、3D建模、后期合成等，需要跨部门协作数周甚至一两个月。而现在，这个 过程被压缩到了几分钟。 另一方面，我们也不能忽视背后的风险。Tim发布的实测视 ...
