Here’s what I do (sort of):
Main system is my studio system. Laptop at home or on the road.
Main system has all mediafiles and the project.
On the Media drive on my Main System, I rename the ‘1’ folder to ’11’ (or another higher number).
I then clone the Avid MediaFiles folder on the Media drive of my Main System onto a portable drive.
I then copy the Project folder to the portable drive.
Then I hook up the portable drive to my laptop. Copy the Project folder to my local drive.
I create a new folder in the Project window, labeled ‘_HOME’. Inside, I place bins with new cuts I make on the laptop.
Any newly created media (imports, renders) will automatically be placed on the portable drive in /Avid MediaFiles/1/ (automatically created).
When done, I copy the ‘_HOME’ folder to the portable drive.
I take the portable drive back to to the Main system in the studio.
I copy the ‘1’ folder from the portable drive to the Main system’s Media Drive (you could rename it 901 to make sure it stays unique).
I copy the ‘_HOME’ folder to the Project Folder.
I launch MC, and now have a ‘_HOME’ folder with the bins with the new cuts.
MC will find any newly created media in that new ‘1’ folder. No need to relink anything.
You could also use synchronization applications to sync the media between the MediaFiles folders, but this is a quick way to make sure you know wherever any new media lives.
