Why should I clear my cache? 

Old cache files can bog down your system and affect current projects. Clearing your cache can solve issues with playback and performance. 

 

What are cache files, anyway? 

When you import footage into Premiere Pro, it creates smaller versions of these files that it can readily access for faster performance. Those smaller files are cache files.

 

Cache files can be found on your computer here.

  • On Mac – Users//Library/Application Support/Adobe/Common
  • On Windows – Users\<username>\AppData\Roaming\Adobe\Common

 

Here's the walkthrough.

  1. Open Premiere Pro! Do not open a .prproj file from your hard drive. Instead, launch the app to get to the home screen
  2. Use the toolbar at the top of your screen to get to your media cache preferences
    • If you're on a Mac, select Premiere Pro > Preferences > Media Cache
    • If you're on a PC, select Edit > Preferences > Media Cache
  3. In the window that appears, select Delete...
  4. From here, you have two options...
    • Delete unused media cache files
    • Delete all media cache files from the system – We recommend this option!
  5. Select OK in the bottom right of the window.
  6. And OK again!

Dang! That is so much easier than the "classic" way of deleting media cache. Thank you Premiere Pro team and thank you, Caroline!

A few more other things I'd like to recommend that any editor would want to know:

 

  1. It is good practice to delete ALL media cache after updating Premiere Pro to a new version or after updating the OS.
    1. Avoids performance issues with trying to playback media using stale media cache.
    2. Avoids export issues as fresh media cache is used rather than cache from a previous version.
  2. When troubleshooting performance or exporting issues, delete ALL media cache, including your current media cache.

 

Again, you cannot delete all media cache from Prefernces unless all projects are closed, including the current one. Choose File > Close All Projects, then choose Preferences > Media Cache and choose to delete all media cache.

 

Adding these comments as I heard a couple of editors are having trouble as all their media cache didn't get deleted. Hope this helps those having performance and export issues!
