Final Cut Pro X, when trying to export audio or video, stalls at a certain percentage and must be forced closed

Ever since FCPX 10.8, some projects are unable to be processed. I do a lot of audio splitting from files and then overlaying it with video and as I play it back, the sound will cut out. It's at this point that the video will stall out later when I try to export it.

I just switched to FCPX 10.8.1 and the same problem persists. This is devastating to me: I cannot process a video I've spent 3 weeks on.

MacBook Pro 16″, macOS 14.5

Tom, I think I figured it out.

I have an adjustment layer that is causing it to mess up. I isolated the tiny section where it was having problems and removed that one adjustment layer, and now it seems to work.

The adjustment file is a file I created in apple motion. It's a trick where you can add things like color luts, color corrections etc. It allows you to place it over many cuts and then color everything below them. I can send the file, but it's really basic.

That is typical of a system that is having trouble playing back. Here's some basics to start with.

What are your Mac's specs?

In the mean time:

Turn off Background Rendering in the FCP Settings.

Delete all Render files via the File menu.

Verify your system drive has at least 15% of its total capacity left as free space.

Percentage = Drive Capacity / 6.67

Can you give the complete specs of the video and audio you’re working with. Also the project properties you’re using.

I'll do what I can.

Rec. 709

Stereo|192kHz

They're .mov files

What else do I need to include?

Tom, it's not the adjustment file. If I try to add any color luts/adjustments to the area, it locks up. If it's at all helpful, I can zip the files up and send them.

By default I have background rendering off.

I have over 500GB.

The problem is that if I try to apply any kind of color adjustments it stalls. It stalls so bad that I have to force quit.
