That is very unfortunate, I have been editing all kinds of things, features, shorts, docs, commercials fro the past year and never ran into a corrupted project. My suggestion is to run the Project repair in the Pro Maintenance Tools from digital rebellion. Did you try duplicating the project? The other possibility is to contact apple support on your problem, they might be able to dig into the code of the project file and fix it too.
Can't seem to download your screen shot, anyway, if you bring up the activity monitor, if FCP X is is using more than 1% of your CPU it is still loading the project. I sometimes switch from optimized to proxy quite a bit with large projects and it can take 10minute + to switch over. So you are getting the beach ball not the crash window?
Do you have any third party effects/plugins installed and being used in your project? I have come across this problem before. Same problem as you. As it turns out FxFactory was causing the problem, and I uninstalled it and my project opened up again. So one of my suggestions would be to check any conflicts with third party effects, especially any used in your current project.
Sorry to hear this; I hope it works out for you. Keep us posted on any developments.
I'm going to be working on a feature length movie next year and was hoping to use FCPX to do it. It would be good if we could get guidelines for the best workflow for large projects (in fact I'm going to start a thread on this).
thx to the advice i got over here i let my mbp fight with the beachball for almost 13h (!!!) ... et voila ... the project was open ....
BUT (and that's a j-lo type butt) ... my 1st action was trying to convert the 90 min compound clip that seemed to cause the problem back to it's original files. it is not yet finished, so i could not just export the project (which of course would have been the "safe way").
now guess what ... simply by trying to select (= highlight) the big compound clip to achieve this, i GET THE BEACHBALL AGAIN !!! ... :-/
the activity monitor says my cpu is runnin' at 100% on fcpx and the memory at 3,43 gb ...
task manager says "fcpx doesn't react" and the beachball keeps rollin' and rollin' (4 about 20 min now) ...
do you guys think it'll recover if i keep runnin' it like that overnight again or is there another way of converting the compound clip without selecting it?
