Final Cut Pro X 10.3.4 (& 10.4) Crashing on Relink – FIX

Have you ever had Apple Final Cut Pro X crash when it’s being relinked? I have had that happen plenty of time. It’s not pleasant, but most importantly, I as a wedding videographer, it wastes my time.

I have a few editors that help me with my longer wedding documentary edits. I send them files and a project file, they edit the documentary edit, and I get the project back at the end. My job is now to check the project before exporting and uploading. But I’ve been running into issues of Final Cut Pro X crashing when I press relink.

Here are a few things to note: We are both using the same exact footage. When relinking, the footage goes past the “validation” in FCPX successfully. BUT when I press “relink” – Final Cut Pro crashes. Restarting FCPX freezes it. And if I do have success, I am accompanied with some shots that are “black” and show up as “no data.” This is the worst scenario.

I have spent a lot of time trouble shooting this exact scenario and with trail and error, finally found a system (or workflow) that seems to have been working with FCPX 10.3.4 each and every time I run into this situation.

The steps are simple. Watch the video if you want to be walked though the process, but like I said – it’s simple.

  1. Open the FCPX project that requires relinking.
  2. Open the timeline that you need to relink. Select all of the footage (cmd+a) and copy it (cmd+c).
  3. Create a new Library. Let me repeat. Create a new Library (not an event).
  4. In the new FCPX Library, create a new project with the setting you need.
  5. Paste (cmd+v) on the new project (this will be pasting the copied timeline from the other un-relinked project).
  6. Once everything is on the timeline, you can now relink. Select the new FCPX Library, and go to File > Relink Files.
  7. You should have success (There are a few catches though, especially if you have multiple projects). This works really well with having one project.


My video does go a bit in depth in some areas – so feel free to watch and share with your friends that have been running into this issue. Let me know if this helped you.

Update 12/14/2017 – Final Cut Pro X 10.4 (FCPX 10.4) does not fix this issue as of right now, so the issue still persists. I have submitted a request to Apple, however, if you are running into this issue as well, I’d recommended submitting a feedback to Apple.

    I did test this FIX workflow and this works perfectly. Thank you so much. I ran into this issue with Final Cut 10.4 (upgrading from an old project), and this help resolve my relink crashing scenario.

    Can’t thank you enough for this. Was having this issue after my external hard drives stopped working and had to replace and working with FCPX 10.4.8. You saved me a lot of choice words…. much appreciated.
