HELP!

I have a large library that has suddenly refused to open without crashing FCP X. None of the back up files work either.

I saw that one could remove events from the library package and get the library to open. This worked.

I replaced the events and the library will not recognise them.

I have time lines with black and red clips. And also in the browser. I cannot reconnect these as they are not recognised as unlinked files.

I dragged a clip in from an external directory and immediately the blacked out file recognised it but the sound only places in the browser and not on the time line. I tried dragging the clip in to replace the blacked out clip hoping it would maintain the cut but it will only replace it and not maintain the cut.

I tried exporting the XML file for the time line hoping to rebuild it but it will not import again because of a corrupt asset.

What can I do to restore the library so that I can keep my Project files?

The crash may be caused by a damaged SQLite database within the library. In general SQLite has excellent data integrity and damage is very rare -- especially if the library is on an HFS+ volume. ExFAT volumes should never be used for FCPX material.

First eliminate the simple items. Make sure you have plenty of free disk space on all volumes. Then run Disk Utility First Aid on all volumes, including the system volume. Then rebuild Spotlight indexes using this procedure: support.apple.com/en-us/HT201716

If that doesn't work, your best solution is restore the library from file backups via Time Machine, Carbon Copy, etc.

If you don't have backups, you can try some experimental techniques I mentioned in this post: www.fcp.co/forum/4-final-cut-pro-x-fcpx/...rupted-library#99926

Included in that post is some diagnostic and repair methods for a SQLite database. None of these are guaranteed to work, but if you have no other option you could try it.

Over the years I have had probably hundreds of FCPX crashes and so far never lost any data or even a single edit. FCPX itself is quite reliable but sometimes you can encounter a hardware/software/plugin/procedural configuration that causes frequent crashes. Overall I am very impressed with FCPX data integrity, and I used to work in database development.

The solutions seems to be simpler. Because I created lots of libraries when rescuing Events from the corrupt library package, I apparently have to have all the libraries open to enable the time lines to population themselves because they are now calling to assets scattered across many libraries.

It looks like unless the project folder is damaged one can rescue projects from damaged libraries without too much trouble as long as one knows the trick!
