FCPX What does the project alert icon mean?

Hi, I tried to export a project as 1080p and after a while received a "Video Rendering Error: -50". Now, 3 of the projects in that event have alert icons. This icon is not listed in https://support.apple.com/guide/final-cut-pro/alert-icons-verd1f977a7/mac. Does anyone know it's meaning?

Good news...


After background rendering completed. I attempted to export again. It said I was missing files. I just closed and reopened FCPX. Alert Icon was gone. So, I again told it to export.


It exported the 1080p video without issue.


So, my best guess is... The combined clips had not completed background rendering. So, although everything looked good and worked inside FCPX, it could not export because those clips were "missing". When rendering was complete, they were no longer "missing". Possibly do to the usage of Combined clips in combined clips in combined clips.


I'm glad it worked itself out. :-)

No missing clips. Just straight export to local HD.


Basically, the project contains 2 videos that kinda looks like this...


4K 360VR video --> Compound clip with Corrected orientation --> 1080p HD Compound clip --> Main 1080p HD project


Both videos are active at the same time providing different viewing angles.


I think it may be because it is a "little" complex and it is still doing some background rendering. Kinda hoping the problem just goes away in a few hours when it finishes all of the background renders.

Free space... Should be good. About 180gb free space left on Project HDD. Export to local SSD with about 150gb of free space.


At this point I'm going to keep my fingers crossed and wait until all background tasks have completed. Then, I'll try exporting again. If that fails again, I'll purge generated files and try again.


Background rendering is still moving along... Slowly... It will be quite a while until that finishes.
