Insufficient disk space?
I just tried to render a ten minute sequence in a FCP project I've been working on, and I got a prompt that said "Render error: Insufficient disk space. Free up space with the render manager and retry?" I didn't want to get rid of any of my renders, so I checked my render drive, and there was 15 gigs of free space on it. Then I checked to see how much total data FCP was using on the drive, and it was only about one gig (and my project is already more than half rendered). So why is FCP telling me the disk is full when it's only using a small fraction of my free space?
I deleted some files from the disk anyway, so now it had about 20 gigs of space, then I started up FCP and tried to render again, and I still got the same message. Then I went into the system settings and added a second scratch disk, which had about 50 gigs of space, but then when I tried to render, I got the same message again!
Finally I went into the render manager and got rid of the undo queue and a few other things, and this time I was able to start the render process, but it said that it would take "70 weeks!" After a few minutes, that number went down to a few hours, but then it stopped when it was about halfway through, and I once again got that "insufficient disk space" message.
So why does FCP think that I have no disk space when I have plenty of space?
I'm using FCP version 5.1.4.
