With premiere you can create low-resolution versions of your 4k videos to be used in your edits. You'll be able to edit in real-time with no lag.

Once you're done and ready to export, Premiere will automatically export to a final format using your 4k files.

Here's how to enable proxies: https://helpx.adobe.com/premiere-pro...oxy-media.html
