Am running FCP 5.1 on a dual 1.8GHz G5 PowerMac, Mac OS 10.5.8.


Yesterday (and day before, etc) it could play sequences in the project I'm currently working on fine... (AIC 1920x1080 - sequence is only about 2 minutes long)


Then today, it's jumpy when playing in the Viewer or Canvas windows...


Just tried restarting... No help...  Tried only having FCP open (have previously had Mail and Firefox running in the background)  Still jumpy.


Is this just a FCP bug or is there something I can do to sort it out??

    Some general thoughts about slow Mac




    • Minimum of 25Gb free space on Start-Up hard disk (4-5 times more if HD-material used)


    • No other programs running in BackGround e.g. Energy-Saver

    • Don’t let HD spin down or be turned off (in Energy-Save)

    • Move other/external hard disks that are not to be used to Trash - To be disconnected/turned off

    • Goto Spotlight and set the rest of them under Integrity (not to be scanned)

    • Set screen-saver to a folder without any photo - then make an active corner (up right for me) and set

    pointer to this - turns on screen saver - to show that it has nothing to show

    (Important during en-codeing processes etc - as to me it goes slightly faster)

    • No File Vault on - Important


    • NO - TimeMachine - during iMovie/FinalCut/iDVD work either ! IMPORTANT

    • Lot's of icons on DeskTop/Finder also slows down the Mac noticeably

    • Start a new User-Account and log into this and iMovie/FinalCut get's faster too - if a project is in a hurry

    • And let Mac run on Mains (if Laptop) - not just on battery

    Bengt, a very concise post.  Would you like to create a user tip for this?  Pretty much everything you suggest would apply to any mac running osX and any version of fcp.  I seem to be the only one allowed to create user tips, but if you'd like to write this up, I'll submit it with your name credited within the tip. 


    email me offlist if you're interested.  mgrenadier@gmail.com


    Not sure why I'm the only able to create user tips in this forum.  I was allowed to create them when apple was just implementing this feature.  Everyone else was supposed to be allowed to contribute when they went "live."  Never seemed to happen, as far as I can tell.
