I am very "New" to the Mac World. I purchased the Mac Pro (Quad-Core Intel Xeon) about 3 months ago along with Final Cut Studio 2. All was working well until this past weekend. I upgraded the OS to Leopard 10.5. Since then, all of my projects drop frames when playing back on the timeline. It's almost like every 30 frames, system will stop and tell me that dropped frames occurred.

I went in and deleted com.apple.finalcutpro.plist and the final cut pro user data folder from the preferences folder. Shutdown and restarted and still had the same issue. I then performed an archive and install of the Leopard OS last night and reinstalled the Final Cut Studio applications. However, still have the same issue.... I am to the point where I would like to reset the computer back to the factory settings and to the old OS. however, not sure of the steps that I need to take.

Any help and/or suggestions you might have would be greatly appreciated...

Thanks in advance for your comments..

    Welcome to the forum jbk69!

    I think if it were me, I'd try a totally clean install of Leopard then the Studio... this involves an erase of your startup disk after you backup the data you want to keep such as docs, email, etc.

    Whether or not you go back to Tiger is up to you... but I think that Leopard can run FCS well enough.

    That said, I've posted before on this subject here:http://discussions.apple.com/thread.jspa?messageID=5599012&#5599012

    There's step by steps in there you should take a look at.

    Also be sure that your media is being stored on a Mac OS formatted hard drive which is NOT your startup disk. Dropped frames are caused by not fast enough disk drives to play the media back OK 99% of the time...

    Jerry, thanks for the quick response... I called apple this morning and they walked me thru a complete erase and clean install of Leopard. Once loaded, I installed Final Cut Studio 2 (took almost 4 hours). Once all installed, I did a software update. Unfortunately, I still have the same issue.. It is real strange. Apple thought it was my media causing the issue. They asked me to download a trailer off of apple.com/trailers and create a project using their media. When I play the trailer in the viewer, all works well.. However, when I put the media in the timeline and play from the time line, the audio becomes distorted and at sounds like I have laid the same track on top of each other with one audio track being a second or two behind the other one...

    I plan to call Apple back and see if they will help me walk thru the process of doing a clean install of The OS (Tiger) that came with my Mac Pro... I am new to the mac world and for the past 3 months have loved every minute of it... However, the past few days have been very frustrating... Hopefully, by reinstalling the original OS, I can get Final Cut working properly...

    My system has two internal hard drives (both 500 gig). I have all of my media on the 2nd internal hard with the OS and applications on the 1st one.

    Reinstalling Tiger is easy.

    The disks you recieved with your Mac are all you need. Follow the prompts... That's really it, but you'll have to reinstall FCS again... might think about moving all those sound loops, and content material to your second hard drive BTW, then just install the apps on your startup disk.

    Those loops and templates files can be located on your drive or relocated to your other drive (mucho faster than reinstalling them from disks), The location of these files are found in the preferences for Livetype, Motion, DVD SP et all...

    FCP has none, and neither does Compressor.

    I just finished doing a clean install of Tiger and re-installing final cut studio... I than did the update software function. Once completed I went out to the apple web site and downloaded the same trailer. Plays perfect in the viewer, however, audio is becomes distored and appears to be out of sync. Looks like I still have the same issue after reverting back to Tiger... The only thing now that is different than last week when all was well, is the fact that i ran the update software... Could my problem be coming from the fact that I have updated all of the software and there is something in the new updates that is causing my issue??

    Any suggestions on how to see if this is the case? Would you recommend that I perform another clean install of Tiger and load Final Cut without doing the updates?

    I rally appreciate your help... Thanks,.

    Let's test your hard drives and see if they have any problems. Download the Aja Kona System Test 2 here:

    http://www.aja.com/ajashare/AJAKONA_System_Testv2.app.tar

    Install it and test each drive. Use the largest sample size available and report the read and write numbers for each drive for us.

    Brian,

    Not sure if I chose the right settings.. I download the Aja Kona System Test 2 application and chose the following settings for both the system drive and the secondary internal drive....
    720 X 486 8-bit
    File Size 4.0 GB
    Check the box that read Disable File System Cache

    The system drive - Write 78.9 mb/s Read 79.6 mb/s
    Secondary Drive - Write 71.6 mb/s Ready 73.2 mb/s

    I will have to plead stupidity, not sure what the numbers are telling me... Does it look like I might have a drive issue based on the numbers listed above or should I have chosen other settings...

    Thanks for your Help!

    Those are great numbers. It's not a drive problem.

    Brian,

    Thanks for your Help.... It is really strange... All worked fine until I loaded Leopard... Now I have erased and re-installed the original OS and still have the same issue... The only thing that I know is different is the fact that after I reinstalled OS and Final Cut, I updated all of the software... Until now, I had not updated any of teh software since I purchased the computer (back in late July). It appears that there is something in the updates that may be causing my issues... But then you would think that there would be many people having the same issues that I am..

    If you or anyone else has any other thoughts and/or suggestions, please let me know....

    Thanks,

    Brian,

    I did another clean erase and loaded 10.4.9 OS back on my system... Reloaded Final Cut Studio 2 and did all of the software updates with the exception of upgrading to Quicktime 7.3.... Appears my issues have gone away. Based on the fact that the only thing different now versus last night is that I did NOT upgrade Quicktime to 7.3.... I feel that QT 7.3 might be the cause of my issues...


    Thanks,

    JBK

    What format of video are you editing? the trailers from Apple's quicktime site aren't supported directly for editing in FCP...

    "Since then, all of my projects drop frames when playing back on the timeline. It's almost like every 30 frames, system will stop and tell me that dropped frames occurred."

    This is actually normal, and not any indication of anything being "wrong" or "broken" with the system. The Canvas image is a low res proxy to begin with. The Timeline will purposefully drop frames, reduce quality, etc, in order to deliver as much RT playback as it can. This is how FCP works. It is also one reason why a proper system has an external post-production monitor, as that will give the full rez playback.

    You simply need to go into your prefs and turn off the Timeline playback warning. Again, it does not indicate anything wrong with your system. The cricical info you need is to be warned about dropped frames on live playback output, not playback in the timeline, which again, is a low rez proxy anyway.

    I've just come across this exact same problem with my new Ali iMac.

    I've been working on a film which is on an external drive 7200rpm and using the FW800 interface. On my Mac Pro and Mac Book Pro it's fine but on the iMac running leapoard (everything is up to date version wise) the project drops frames! The other 2 machines are both running 10.4.9.

    If I load a clip in the viewer it plays fine but when I drop that same clip to the timeline it only plays for about a second then the warning comes up. I haven't seen dropped frames on my system since FCP 3 running off the internal HDD!

    I've gone through most issues (bearing in mind I teach this application!) but cannot work out why it will not play back. It even plays back on an old Powerbook 17" running FCP 4.5HD (the clips from the HDD that is) so why is my shiny new iMac making such a bad job of it?

    Very frustrated!

    BTW I have a DVCPro 50 clip on the external drive that plays back fine so I know data rate is not a problem. If it can handle that it should be able to handle a single stream of DVPal which is what the problem project is.

    REgards.

    K.

    Just to comment on Bens post...this is NOT normal. If you have your system setup as Apple recommends you should not see dropped frames. OK if you have 20 real time audio tracks or unlimited RT switched on it will crop up, likewise if you use low compression clips off of a slow HDD. However from what the OP says, this is some kind of Apple bug, certainly from the tests I've done.

    I ran the disk speed test, all my drives are in excess of 70MB per second, plenty for DV!!!
