Cannot export file in Final Cut Pro

I didn't watch the whole time to see what was going on, so I don't know how long it took, but it exported to the desktop.

I exported using ProResLT. ProRes422 would obviously make a much larger file.

Why is everything in the project a compound clip? That creates an entirely higher level of complexity for the processing, and of course I don't have any media to decode, which is again more complex in compound clips, which have to be processed, stored in memory, and combined with other compound clips in your project. It's really very difficult, and if there's any way to get out of the compound structure it might make it easier on the system. I'm using an M1 Max MBP with 32GB RAM.

I downloaded your xml file, opened in FCP.

It all looked normal (of course, all the media were missing, as expected).

I tried to share. It stood there "preparing media for share" and the application was unresponsive

for several minutes until I force-quit it.

Is that what you are experiencing?

I have to attend family duties now, will try later to look at the project and the xml to see if I find something.

I will try to have a look at the file.

What exactly happens when you try to export?
