Relink Prevention
Relink Prevention is a feature for Final Cut Pro users.
Relink Prevention reduces the number of times you need to relink Clips to media in a Final Cut Pro Library. When adding or importing a Library in Postlab, MEDIA LOCATION defines how a Library's Storage Locations will persist when each Team Member opens that Library from their Mac.
Set a Library's MEDIA LOCATION to either Individual or Shared when adding or importing a Library.
MEDIA LOCATION > Individual or Shared


Shared Libraries are FCP's default treatment of media storage: the volume name of your media storage stays the same or rarely changes. Shared requires Team Members to use shared storage – like a NAS or Postlab Drive – or local storage with identical names and thus file paths. FCP will not require relinking if all media is on shared storage. All media outside of the Storage Location requires continuous relinking using Shared.
With Shared Libraries, the Team Member that first opens a Library sets the Library's Storage Locations from their Mac, propagating to each Team Member. When the next Team Member opens that Library, they can get right to work if the volume or folder names are exactly the same. Otherwise, FCP will prompt them to reset the Library's Storage Locations, resulting in relinking. When the original Team Member reopens that Library, FCP will prompt them to reset the Library's Storage Locations again, resulting in more relinking.
If all your media is on Drive, use Shared.


Individual Libraries allow the team to use independent Storage Locations on each Mac, removing the need to use identical volume names or paths. These Storage Locations will persist on that particular Mac each time they open that Library. Since each Team Member sets the Library's Storage Locations once from their individual Mac, it's possible to relink Clips to media only once, then never again, with an Individual Library.

Opening a Library from Postlab

The first time you download and open a Library from a Postlab Production, FCP will prompt you to define your Library's Storage Locations. If you see a Storage Location in capital letters, it needs to be set.
More info on setting a Library's Storage Locations is available in our Initial Workflow Checklist for Final Cut Pro.
Once your Library's Storage Locations are set and you upload the Library to Postlab Cloud, Postlab shows you which files are Online or Offline in the Document's Media Status indicator without having to open the Library first.


In Postlab, FCP Libraries are Documents added to a Production. When you open a Library in Postlab, Postlab downloads your Library to a local Production bundle, then uses that local copy to track and upload changes to Postlab Cloud. When re-downloading a Library from Postlab Cloud, you will have to redefine the Library's Storage Locations in FCP, then relink Clips to media.
Here are some examples of when you'll be required to redownload a Library in your Production:
  1. 1.
    After logging out of Postlab, locally cached Productions are moved to the Trash.
  2. 2.
    Select a Library in your Production, then choose [Remove Local Copy] from the Document's Options menu.
  3. 3.
    The locally cached Production becomes corrupt, and Support directs you to remove then re-download it.

How can I learn which media is ONLINE or MISSING?

Once a Library's downloaded in your Production, Postlab's Media Status indicator will tell you which files are ONLINE or MISSING.
DOCUMENTS > Library > Media Status

When I copy Clips, Projects, or Events between Libraries, I have to choose to include Media or ...without media. I can't copy media into my Library in Postlab, but I don't want to relink Clips every time I copy something between Libraries. What should I do?

When copying something from one Library to another, select Include: Media then enable Original media and Proxy media:
Even if you don't want to relink to Original Media, enable Original media. FCP will present this dialog: Original media does not exist for some clips, then click [Continue] and relink to any Original Media later:
FCP will not copy any media into your Library. Instead, FCP creates symbolic links to your media files in the destination Library.
