智能媒体夹Smart Bins

智能媒体夹（Smart Bin）是按元数据规则自动收纳片段的媒体夹——你定义规则，它负责填充：片段符合规则就自动出现，不再符合就自动消失。

• 规则即成员：成员资格完全由规则决定，不能像普通媒体夹那样把片段拖进去。
• 实时更新：片段元数据一变，结果立刻刷新——勾上 Good Take，片段瞬间进夹；取消勾选，立刻出夹。
• 两种来源：My Smart Bins 是你自建的规则夹；Keywords 下是打关键词时自动生成的夹（见 keyword-smart-bins）。
• 随时改规则：右键自建智能媒体夹选 Edit 可调整条件；自动生成的关键词夹不可编辑。

A Smart Bin is a bin that fills itself based on metadata rules — you define the rules, it does the collecting: clips that match appear automatically, clips that stop matching disappear.

• Rules decide membership: you can't drag clips into a smart bin like a regular bin — matching the rule is the only way in.
• Always up to date: change a clip's metadata and results refresh instantly — check Good Take and the clip pops in; uncheck it and it's gone.
• Two sources: My Smart Bins holds the rule-based bins you build; the Keywords group holds bins generated automatically when you tag clips (see keyword-smart-bins).
• Rules stay editable: right-click a custom smart bin and choose Edit to adjust it; automatic keyword bins can't be edited.
