I did make a large video. It's almost 300 mb and I made three copies of it for different variations of it - but that's not even 1 gb! Or am I not understanding how FCPX uses space?
That's not large at all. A one minute Pro Res HD video could be 1 GB.
I also doubt having about 28% free space on the boot drive is the problem.
Are apps other than FCP running OK?
1: How long is that video, and did you make it in FCPX?
2: FCPX stores user data in two locations:
A: ~/Movies/Final Cut...
B: /Voumes/SomeHDD/Final Cut...
See what size those folders are..!
3: Slowdown can, if you un out of RAM and have a lot of Apps running, cause the system to 'swap' data to the Virtual Memory in the HD, that is about 1-5000x slower than your RAM.. yes, it takes time, but should mostly be seen when you switch between applications.
You can check this in Activity Monitor, if the Page Ins number is running up, the system is activly using your HD as virtual memory.
Yesterday I noticed that some videos had current render dates, even though I hadn't touched them in a while - odd. Anyway, I deleted all the render files and I have now made up 100 of the 130 gig. Here is what my activity monitor looks like tonight.
I am not sure how to read this, though.
My computer has 8 gb RAM.
