Waveform cache files

Hi everybody,
What exactly is a waveform cache file and can I open these in final cut pro? The reason I ask this is because I have managed to loose some Quick time audio files which I now need. I have managed to find the old waveform cache files and was wondering if there is any way of using these to save the files? Not really holding up much hope but though it was worth a try.
Thanks
Sara

Hi
The waveform cache files do not contain actual audio but data about the waveform as displayed in the Sequence timeline in FCP.
I'm afraid they will not bring back your audio for you.
Regards,
Jim

  • Can't Open Final Cut - "Waveform Cache Files Folder does not have read/....

    I am new to Final Cut and macs, so please bear with me.
    I have created an animation in Final Cut pro (5) using stills. The project takes up a lot of space, which is why I have moved the 'Final Cut Documents' file onto my external hard drive. However, I relocated/reconnected the project files when I next opened the project and all was peachy.
    Last night when I had the project open I got errors about not being able to save the project. This was my first problem, but is now insignificant compared to this new problem this morning:
    I cannot open Final Cut. I have an error saying 'The Waveform Cache Files Folder does not have read/write access. Please select a new folder in the System Settings Dialog or correct the problem on disk'. Final Cut then proceeds to shut down, so I cannot change any user settings within the program.
    I have made all Final Cut folders read/write as well as my external hard drive and anything else with Final Cut on it. It still presents this warning.
    A final confession: last night in (I think?) User Preferences I changed some of the settings to my external hard drive (I'm not even sure what settings...I just checked boxes next to the Hard Drive and unchecked a box next to the laptop drive), hoping it would just save the project to it, rather than on my laptop. This may have contributed to this new problem...maybe not.
    PLEASE HELP...this animation is due Monday.

    Thanks for your reply - it sounds like it will work, but I can't delete one of (yes, I made multiple copies, but have been able to delete the others) the Waveform Cache Folders as it comes up with the error "The operation cannot be completed because one or more required items cannot be found. (Error code -43)." Is this the cause of my problems? How do I fix it?

  • Waveform Cache Files.  Delete?

    What exactly are waveform cache files and can I delete them without worrying about screwing something up?

    I guess the only thing you should never delete is your capture scratch? Everything else can be trashed?<<</div>
    Even your captures can be trashed .... AFTER you've finished and delivered the final project and the client has accepted it.
    I usually only permanently keep project files and any graphics I created for the project. Everything else gets tossed.

  • Problems with non-existent waveform cache...

    I previously posted this:
    +I cannot open Final Cut. I have an error saying 'The Waveform Cache Files Folder does not have read/write access. Please select a new folder in the System Settings Dialog or correct the problem on disk'. Final Cut then proceeds to shut down, so I cannot change any user settings within the program.+
    +I have made all Final Cut folders read/write as well as my external hard drive and anything else with Final Cut on it. It still presents this warning.+
    And was replied to with this:
    +Delete the Waveform Cache Files folder in the Finder.+
    +Open Final Cut Pro by clicking the FCP application icon -not by opening a project.+
    +In the Menu bar click on Final Cut Pro > System Settings. Reset the loction of your Waveform Cache Files folder. The folder will be re-created in the directory that you choose.+
    So, I have deleted all the waveform cache files.
    I copied the Final Cut Pro Documents file onto my hard drive and deleted the original from my laptop. Last night all was running fine.
    This morning I have the same warning as earlier:
    "The waveform cache file does not have read/write access."
    There IS no waveform cache file? I've done searches on both my hard drive and the external hard drive and all that remains are the invisible outlines of the files I deleted last night.
    ???

    P.S. I still have my Final Cut Pro project file (which I am desperately praying is my saving grace) but I can't find other associated files.

  • Waveform cache, thumbnail cache and autosave vault

    Sorry but I still have a couple more questions.
    Should i be moving the waveform cache, thumbnail cache and autosave vault over to external hard drive with the media? And where and how are the project files stored on my internal system drive? Just trying to organize the location of everything before I go any farther!

    Hey digginin to my Mac. I am where you were a bit ago, and I think I understand your question about where to set those cache files, and I am a little unclear on this as well.
    I am probably making a mountain of a mole hill, but I believe you are talking about that bit at the bottom of the window of the Scratch Disc pane of the System settings. I am working my way through Tom Wolsky, and he seems to say to set those three things (waveform cache, thumbnail cache and autosave vault) to go to the external. It's a bit unclear to me though. I currently have them set for my documents folder on my MBP. And in my documents folder is a folder called "Final Cut Express Documents" in which are six folders (Audio Render Files, Autosave Vault, Capture Scratch, Render Files, Thumbnail Cache Files, Waveform Cache Files). I set up a scratch disk, and captured some video to it. It currently has those same six folders. Everything okay so far?
    I have just set up another scratch disk, which will actually be my main scratch disk, and will be used for a pretty big project involved many hours of video. I haven't captured any video to that yet. It only has three files (Capture Scratch, Audio Render Files, and Render Files). I guess the other three get created when I capture some video to it. And I guess I can select that particular scratch disk when I go to capture the video.
    Am I in the ballpark over here? Thanks in a advance.

  • Best place to store THUMBNAIL AND WAVEFORM CACHE?

    I was taught that when creating a new project, it's best to create a folder
    on a seperate media drive, and direct your scratch discs, thumbnail & waveform cache as well as the autosave vault to that drive & folder. This way,
    everything associated with that one project resides in that one folder on
    your media drive, seperate from the computers hard drive and if you have
    to move the project to another computer or delete everything associated
    with the project, you just move or delete that one folder.
    This has served me well in the past,...but,
    I was recently working with (6) different G4 1.2 laptops running FCP 4.5.
    It was a training class and the machines were working 8 hours a day for
    6 days straight. They were not networked together in anyway.
    Periodically, everyone of them would "lose" the waveform cache and thumbnail cache pictures while editing. I don't mean the folders would
    disappear, I just mean they'd stop generating the little thumbnails and
    waveform pics on the timeline. The temporary fix was to just save the
    project, close FCP, and reopen the project. They'd all pop back in and be
    there again for a while.
    #1 - Anybody know why this would happen?
    #2 - It was suggested to me that to avoid this happening in the future,
    that you should should direct the thumbnail and waveform cache folders
    to live on the HARD DRIVE of the computer, the same one with the app,
    and NOT in the same folder as the seperate media drive where you capture
    and store your video.
    This goes against everything I originally learned, but was wondering what
    others might have to say or have experienced on this point.
    I'd appreciate any input. Thanks.

    gulp ... jumps right in with both feet ...
    I think you were taught wrong.
    this is not the official path as laid down by the gods of fcp
    conventional wisdom suggest that you should set your scratch disk location once and then let fcp organise everything else.
    re your questions:
    1. no idea ... not the end of the world but certainly a weird glitch tho.
    2. some do, some don't ... tiny files w. very low overhead, location shouldn't be a factor in the problem you noted

  • CS2: Adobe Bridge Cache File on Desktop...Why?

    For some unknown reason...CS2 has started placing "Adobe Bridge Cache" file shortcuts on my desktop. When I click on one, I receive a Win XP error message that says the file .bc is unkown and can't be opened.
    These shortcuts have never appeared before. Now the simple act of opening Bridge and looking at jpeg files seems to initiate it.
    Questions: Why is PS doing this? Do I need to pay attention to it? If not, how do I stop PS from cluttering up my desktop.
    Thanks!
    Ed

    Ed,
    Yes you can. The cache facilitates the quick display of images in a folder.
    When there's no cache, Bridge has to render thumbnails from every image file upon viewing a folder's contents. This can take a couple of minutes.
    Rob
    P.S.
    >I do, indeed, have image files in a folder on my desktop.
    This would mean that there is a cache inside that folder, *not* on the desktop itself.

  • Remove caches file's automatically if you delete a folder from your drive???

    Gday,
    First off all sorry for my poor/bad English.
    When i remove/delete a folder in bridge, where will by the cache file of this folder??
    Does it also Remove/delete automatically, ????
    Or should I in the preferences box, tick on the (automatically Export Cache to folders when possible) option???
    Already many Thanks,
    Henry

    As the others say, no, the backup copy won't be deleted immediately, but it will eventually.
    If you want to delete all backups of a selected item, such as for space or security reasons, see #12 in Time Machine - Frequently Asked Questions.

  • Is it safe to delete the cache file folder from library

    is it safe to delete the cache file folder from library ?

    As I understand it Robo doesn't really 'do' third-party
    source control. We use SourceGear Vault, but really only as a
    repository for the files. We can't really work concurrently because
    Robo needs exclusive access to the top level project files. But it
    kind of works for us, because we're on opposite sides of the globe.
    I see what you're saying on the 'local' versions of (say) the
    cpd files conflicting. If anyone else has an informed view, I'm all
    ears. We've set it up this way ourselves - I don't know of anyone
    doing the same. If someone tells me this is a bad idea, I'm happy
    to think again.
    Cheers!

  • User sip folder have many .cache files with 4kb and the folder is becoming full and Lync Client stops working

    User sip folder have manu Mailitem&username&.cache files until folder is full and Lync client stops working.

    Hi,
    You can try to change the Lync Profile name. After you do it, Lync will create a new Profile. The Lync Profile path is following:
    %UserProfile%\AppData\Local\Microsoft\Office\15.0\Lync
    If the issue persists, please repair Office 2013 and then test again.

  • How can I store ALL cache files in ONE place? i.e. in one folder

    Firefox 28.0
    WIN xp
    I would like all the cache files to be maintained in one single folder and not spread over multiple folders in a directory structure (as it currently operates).
    (current cache location)
    C:\Documents and Settings\xxx\Local Settings\Application Data\Mozilla\Firefox\Profiles\xxxx.default
    (multiple folders and sub-folders)
    Is there some way for Firefox to do this?

    AFAIK that is not possible.
    It is possible to choose an alternative location but the structure will remain the same.
    * see http://kb.mozillazine.org/Browser.cache.disk.parent_directory
    I do not know whether you have discovered it but you cache details may be accessed from Firefox by navigating to ''about:cache'' . About:cache details the three caches.

  • Can't write cache file for while creating domain in soa 11.1.1.5 on HP-UX

    Hi,

  • IPod photo cache file - how do I locate it?

    Hi all,
    On my iPod nano I keep getting the "some of your photos were not copied because they cannot be displayed on your iPod" message, but the photo albums I am syncing do not contain the photo mentioned in the warning.
    I have had a look around and noticed that one member said there is an iPod photo cache file that does not get updated. So, I want to delete that and then resync my iPod, in the hope that this warning message will not re appear. The problem is I don't know where it is located.
    For the record, I have also recently restored my iPod using iTunes 7.1.1 and this still occurs.
    Thanks in advance,
    Anthony.

    well any suggestion would b appreciated, thanks!

  • I just found an error in the file name for my Camera Raw Cache file.  How do I correct it?

    I just found an error in the file name for my camera raw cache file.  The error is in my username.  I don't know how to correct the error or if I should just leave it.  I'm not sure where my cache file is stored on my computer.  Any help would be appreciated.
    Thank you

    Since you are on a Mac if when you first set up your account you left out the i in Wilson nothing you do will change that. The REAL account name will always be alicewlson. Once an account is created you can't actually change the name of it. You can change the name that is displayed but not the REAL account name.
    Simplest thing to do is stop worrying about it. Everything is as it should be, that is except Wilson being spelled without the i.
