Activity Forums Apple Final Cut Pro Legacy Compressor or QMaster eating up my startup disk

  • Compressor or QMaster eating up my startup disk

    Posted by Adam Pearson on April 18, 2009 at 9:27 am

    I’ve been reading posts both here and on Apple’s discussion pages and I can’t seem to find an answer that clears up the problem. I’m working on a project in FCP 6.0.5 and exporting my finished projects to Compressor directly from Final Cut Pro (file>export>using compressor). When I submit my job in Compressor it starts rendering to the folder on my external hard drive I’ve designated as the destination but while it’s rendering something is also devouring space on my startup drive. Once the render is complete the space is freed again on my startup disk (last time it took all 2 gigs of my free space). I’ve read posts about similar issues but the only suggestion I found to fix the problem was to locate the folder /var/spool/qmaster where Qmaster dumps its cluster storage but I watched that folder during my last render and it’s not what’s filling up. If anyone has any ideas please let me know…This is puzzling me to no end.

    I would check your preferences and set Cluster Options to “never copy source to cluster.”

    Had this setting when I rendered. Sorry about not mentioning is before but it didn’t seem to change anything. 🙁

    I think I figured it out. The space that’s getting taken up is in the Virtual Memory Cache. I looked at the var/vm folder and it was loaded with almost 4.5GB of files. I’ve been running the computer rendering non-stop for several days so I guess it just built up after all that time. On restart I got all of the free space on my hard drive back…5.01GB from 861MB. Whew. 🙂

    Hi Russel,

    I’ve been looking for an answer to this… It’s my first time using compressor and then burning the dvd on dvd studio pro. I just finished a 90 min HD movie and when I ran it through compressor, it seems to have eaten up A LOT of my disk space. I started with about 25 GB and now down to only 4.

    I tried retracing my steps and went into my FCP render folders, nothing there. Looked for a compressor folder, but nothing in there. I’m assuming some sort of rendering was done and put somewhere mysteriously… I don’t know if this is accurate, but I thought maybe I could ask you for some help if you know what’s going on.

    My FCP files are directed to my external hard drive with more space, but my macbook is the one that seems to have gotten the brunt of the compressor’s work.

    I appreciate it!

    Best,
    Jullian

    Great- but where do you find the var/vm folder?

    Thanks!
