Here a short compilation:
1. Select all you Media Files in the Project’s Browser Window. Right click -> Open Media Manager.
2. Choose “Re-compress” (Here select Apple ProRes Proxy). Choose a new location (create folder for this) – ideally not the same HD than your Hi Q ProRes files. And save new Proxy version as seperate Project (give it e.g. your previous project name plus “Proxy”. And then press ok and let the computer re-compress all your files to Proxy size.
3.Now, you can open the new Proxy Project, do all you editing. When you are finished. You select all your clips again, then right click “Reconnect Media” and reconnect it to your original HD HiQ Files.
C’est tout! You are done.
