媒体池Media Pool

媒体池（Media Pool）是项目里存放全部素材和时间线的管理中心——导入的片段、整理用的媒体夹、新建的时间线，都住在这里。

• 一切素材的落脚点：不管用哪种方式导入，片段都先进媒体池；时间线也作为一种元素存在这里。
• 媒体夹 = 文件夹：用 Bin 给素材分类，Bin 里还能套子 Bin，逻辑和电脑上的文件夹一样。
• Master Bin 是顶层：每个项目自带一个 Master 媒体夹，其余所有媒体夹都挂在它下面。
• 多选连看：Cmd（Mac）/ Ctrl（Win）点选多个媒体夹，内容合并显示，方便跨夹比较。
• 链接而非复制：媒体池里的片段只是指向硬盘源文件的链接，源文件被移动或删除，片段就会离线。

The Media Pool is the management center that holds every piece of media and every timeline in your project — imported clips, organizational bins, and new timelines all live here.

• Where all media lands: no matter how you import, clips arrive in the Media Pool first; timelines live here too, as another kind of element.
• Bins = folders: sort footage with bins, and nest bins inside bins — same logic as folders on your computer.
• Master bin on top: every project comes with a Master bin, and every other bin sits inside it.
• Multi-select viewing: Cmd-click (macOS) / Ctrl-click (Windows) several bins to see their contents merged — great for comparing across bins.
• Links, not copies: clips in the Media Pool only point to source files on your drive; move or delete those files and the clips go offline.
