Stabilization causing render hangups?

I've noticed that, too. If I do render, then close the program and come back, it'll show it's not rendered (double-whammy).

When you say 'library bundle', I assume you mean the project file (the purple icon with four stars). IE... control click the Library File, then >Show Package Contents>Event Name (event name being whatever you named your event file)>Analysis Files.

Trash 'Analysis Files'?

This might all seem obvious, but might help out somebody else that stumbles on this.

I get the error message: "Background tasks are not yet complete. If you continue, these effects may be missing or have reduced quality: Stabilization".

Meanwhile... there are no background tasks running. So if I can manage to render the clips with stabilization turned on, then I have no problem exporting. My problem is, the renders stop on their own, forcing me to render the same timeline over and over and over again, until it completes.

Roger that. When I go into that folder, there's another folder for 'Stabilization'. So I bet you're onto something.

I also just noticed that there's an update for FCP (10.5.4). I'm doing that on the mini... so I can't test it there quite yet. But just deleted that file on the MBP and successfully exported a shorter file with stabilization turned on (where I couldn't before the rendering). So, I think you're definitely onto something!

Welp... it appears I got lucky yesterday trying a test on that shorter video (4 minutes long) by removing the Analysis files. I was able to export it without even rendering the stabilization effects.

But I've been trying to export longer videos (1-2 hours long) after trying this possible solution, and I'm back to the same problems. Renders will not complete... stop abruptly... have to keep forcing the project to render over and over again. Project won't export without rendering all stabilization effects, and if I try, I get that warning message about background tasks... even though there doesn't appear to be any background tasks being performed.

I know it may be a mystery to us, Tom, but maybe somebody else will see this and know a solution... or the FCPX team will catch wind of it and fix it in a future update. What's the link to the 'suggestion' form that can be sent to the FCPX team? I can explain it there.

I'll attach the warning message I get when trying to export a project that isn't rendered with stabilization effects in it... along with another screenshot of what I get right before that. It's a progress bar that runs for about a minute before it gives the the background tasks warning message.

Finally, I'll try exporting one of these videos by hitting 'continue', without rendering, and see if it makes any difference. For all I know, they may very well export just fine with the stabilization effects functioning properly and this is just a glitch that can be ignored.

Will report back if that's the case.

Thanks for the reply, Terry!

The footage isn't anything unusual. Standard 1900x1080 MPEG-4 files directly from Canon video cameras (XA-50, EOS-R6). I also utilize AVCHD footage (1900x1080) from Canon XA-10's. When I import, I always optimize, everything. So all of my footage is already transcoded. I've been a FCP user since it's inception... not my first rodeo, lol. Regardless of the source video (AVCHD or MPEG-4), this problem persists when trying to export.

I will give resetting preferences a try... didn't think of that! Thank you.

I keep all library's stored on external HD's. Specifically, 8TB Western Digital thunderbolt drives (for the most part). The one I'm working from currently is at least half empty (roughly 4TB's avaialble).

Hmmm... it's listed in there, but not checked off. Should I check that off to give it full access... or does it being listed already mean it has full access?
