I've been working on a large editing project for a long time now. I am very very close to finishing, and now my computer is acting up. The main problem is that the functions of FCP will just "freeze up" on me intermittently. I'll click somewhere in the timeline, and when I hit spacebar to play, it will pinwheel on me for a REALLY long time. Then it will try to go, but then it will pinwheel again, and try to "catch up" to itself. If I hit the spacebar to stop & catch up myself, it will try to process all these commands at once it seems, and mayhem ensues. I've had some luck with clicking on another FCP window, like a viewer window or something. That makes it stop somewhat quickly, because it's a definitive action, unlike hitting the spacebar, which once you start, who knows whether your starting or stopping... Anyway, that's usually just a temporary fix to get me to where I can save. After that, I quit, logout, restart, shut down, what ever I can try. Sometimes that works, but seemingly only for about a max of 45 minutes until it freezes again. Subsequently, the freezing will occur at shorter intervals. I've tried clearing space on my drives, and eliminating unnecessary media from the project, but is there anything else I can do? Some have suggested reinstalls for this kind of thing, or deleting the preference folders, old render files, etc. I would LOVE some advice on this, as I have a deadline looming, and producers breathing down my neck. thanks!
