About transferring files

Although it is possible to edit assets residing on file-based media, such as P2 cards, XDCAM cartridges, or SxS cards, Adobe Premiere Pro performs faster if you first transfer the assets to a local hard disk. Using Windows File Explorer (Windows) or Finder (Mac OS), transfer files from file-based acquisition media. Then, import the files on the hard disk into Adobe Premiere Pro projects.
