B. 二分定位 + 邻域采样（我推荐） 把配置的语义从"这就是要生成的 10 档"改成"允许搜索的参数梯度"（比如分辨率梯度、帧率梯度、质量梯度三张表）。运行时： 1. 用每个组合只编 2 帧的方式粗估体积（很便宜）； 2. 靠单调性做二分，几轮就找到"体积刚好不超过目标"的参数点； 3. 在这个点周围取 10 个组合（略高、略低各几个），完整生成。 成本大概是十几次估算编码 + 10 档完整编码，和现在基本持平甚至更省（估算只编 2 帧）。效果是候选真正围绕你输入的目标分布——比如你填 30 KB，出来的就是 22、26、29、31、35 KB 这种，而不是 5 KB 和 300 KB 各一个。 代价是你现在这套配置格式要推翻重做——从"精确档位表"变成"参数范围表"
