How to resolve a crash in Final Cut Pro

As we explained here, even in modern hardware and software systems, a demanding video project may introduce unexpected performance results. For example, audio or video frame glitching, slow application response, "beachballs", etc. are some of the most common. However, the major problem, which everyone wants to avoid, is an application crash!

If you’re reading this article, then you probably had a bad time with ERA plug-ins and Final Cut! If that’s the case then here some steps that might help you recover your project and resolve the crash. 

#1 Check System Requirements

We design our products to be compatible with every Audio and Video Editor that supports audio plugins. We're also working on the deeper integration of our plug-ins with every host. However, depending on the feature of each plug-in, compatibility may change even for the same host! 

For this reason, we strongly recommend to check the compatibility and system requirements before using the plug-ins.

#2 Re-install ERA Bundle

Follow the steps below: 

1. Quit your project
2. Uninstall ERA plug-ins
3. Reinstall ERA plug-ins
4. Open your project again

#3 Reset Audio Unit cache

If the first workaround didn’t work, then you might need to make refresh to the Audio Unit Cache. To reset Audio Unit Cache:

1. Quit Final Cut Pro
2. Go to /Users/UserName/Library/Caches/AudioUnitCache
3. Delete the included files

#4 Reset Final Cut Pro Preferences

Resetting preferences don't affect your libraries, projects, or media. However, any custom preference settings will be reset to their default settings.

Before resetting preferences, choose Final Cut Pro > Preferences and note any specific settings you've made. Learn more about Final Cut Pro preferences.

To reset preferences in Final Cut Pro:

1. Quit Final Cut Pro.
2. Hold down the Command and Option keys, then open Final Cut Pro.
3. Click Delete Preferences
4. Try to reproduce the issue you were experiencing. If the issue no longer occurs, open Final Cut Pro preferences and reapply your custom settings.

#5 Reset Final Cut Pro cache

Since there's no automated process to reset the Final Cut Pro cache you need to do this manually.

1. Quit Final Cut Pro
2. In Finder, click on the Go menu, hold down the [Alt/Option] key and click on Library.
3. Go to Preferences and move the com.apple.audio.InfoHelper.plist file to your desktop.
4. Restart your computer and try to open a new session in FCPX
