Fixing "corrupt" QT files?

Hi -
After a recent crash of my RAID, many QT files will not reconnect in FCP. They throw errors like, "not a format QT understands," and others. Basically, they will not play.
However, if I xfer them to a Windows machine, the QT files play just fine.
Which leads me to believe that there is a level of corruption...but that the files might be able to be globally fixed. Is this possible? Clearly the media is still there...and it looks fine....but something in the file type/creator data (?) has been altered.
I could move ALL the media to a Windows system, then port it back, but that will be probably as time consuming as recapturing the media...hence my search for a utility which might help.
Thanks for any and all ideas.

I've been round the bend with this problem a couple of times, and my conclusion is that you're hornswaggled.
Used to be that all the resource data for a data file was kept in the Resource Fork. In current versions of Tiger, that's not the case, and resurrecting the correct resource data is impossible for us mere mortals.
I'm not saying it can't be done, but I haven't found anyone willing to go on the record who can do it.
YMMV.
EDIT: Hornswaggled (hornswoggled, actually) was the wrong word to use. I should have said you're hosed.

  • Fixing corrupt JPG files

    Is there any good software out there for fixing corrupt JPG files?

    Corruption damage in a .JPG entails data loss and the JPEG format does not contain redundancy, so there's no way to recover what's lost. Usually if the damage is found towards the end of the file, you can "recover" the good part by truncating it. If you want to do it interactively, you can try using software such as [The Gimp|http://www.gimp.org>, or its (very) expensive brother, Photoshop.
    To do it automatically (batch mode) you can investigate if any of the tools in the [Image Magick package|http://www.imagemagick.org/script/index.php] helps. Note that these are command-line Unix tools.

  • "zip" Terminal command no help fixing corrupt zip file; any other workarounds?

    I downloaded a ".zip" file containing some files that I need to access.
    When I double-click on it, I get the "Unable to unarchive 'xyz.zip' into '[foldername].' ( Error 1 - Operation not permitted )" message, which many people report when they try to open a corrupt zip file.
    I also tried opening the file with "StuffIt Expander," "Archive Utility," and "The Unarchiver," as well as some specialty zip-compression programs, but none were successful.
    I then installed the very useful "Archive.qlgenerator" plugin (http://homepage.mac.com/xdd/software/archive/) which allowed me to at least see inside the zip file using OSX's "QuickLook" feature. Lo and behold, all the files that were supposed to be in the zip file are indeed in there, as they should be. The problem is not that the zip file is empty, the problem is that it has become corrupted somehow.
    So, what I need to do is either "fix" the corrupted zip file, or alternately find some way to extract the needed files using brute force.
    Following tips given on various forums, I tried using OSX's "zip" command in terminal (http://homepage.mac.com/kelleherk/iblog/C1901548470/E731143104/index.html and http://hintsforums.macworld.com/showthread.php?t=132146). I was able to use it properly, but unfortunately neither the "-F" nor the "-FF" commands were of any helping in "fixing" the zip file. The "-F" command incorrectly said that the zip file was empty and that there was nothing to fix; the stronger "-FF" command came back with
    Could not find:
      xzy.z01
    Hit c      (change path to where this split file is)
        s      (skip this split)
        q      (abort archive - quit)
        e      (end this archive - no more splits)
        z      (look for .zip split - the last split)
    or ENTER  (try reading this split again):
    ...but none of the options produced any result. Pressing "z" gave me
    Could not find or open
      xyz.zip
    ...which means that even "-FF" could not get past whatever problem had corrupted the file.
    So: is there any built-in way for Mac OSX to fix or extract the contents of a zip file corrupted like this?
    Alternately, is there any third-party shareware or freeware that will do the trick?
    (I don't want to have to spend big $$$ on a commercial program since all I need to do is open a single zip file. And there is no way to contact the zip file's original creator, so I can't download an uncorrupted version.)
    Any help would be greatly appreciated.

    Mark:
    When I try your first suggestion in Terminal ("unzip -t /path/to/file"), I get this message:
    Archive:  /xyz.zip
      End-of-central-directory signature not found.  Either this file is not
      a zipfile, or it constitutes one disk of a multi-part archive.  In the
      latter case the central directory and zipfile comment will be found on
      the last disk(s) of this archive.
    unzip:  cannot find zipfile directory in one of /xyz.zip or
            /xyz.zip.zip, and cannot find /xyz.zip.ZIP, period.
    When I try your second suggestion ("unzip -l /path/to/file"), I get the exact same error message. (And yes, I am fixing "/path/to/file" to be the correct path to the actual file).
    And no, it is not really part of a multi-part archive. (Or at least it wasn't supposed to be; only one zip file is available, and there was only supposed to one.) Perhaps the zip was mis-encoded in the first place, so that the person who created it accidentally did something wrong which the unzip applications are interpreting as this file being part of a multi-part archive; but even so, all I have is this one file, so I need to fix it as is, or extract its contents as is, since I have no way to contact the original creator to do it right this time.

  • How to fix corrupt dll files

    Hi,
    Happy New Year!
    May it bring all of us, Good Health, Happiness, Harmony & Prosperity!
    I will like to let you know that a few month back, I bought this S10-2 directly from Leveno, USA, but regrettably with in a a few days, I realized that this machine has the following problems:
    1) The "dll files" are corrupt, details are as follows:
    advpack.dll
    dnsapi.dll
    gdi32.dll
    msv1_0.dll
    2)  Power Options:  Control Panel / Power Options / Advance (Power buttons) has 3 options (default)
    a) When I close the lid of my portable computer : Stand by
    Kindly note that when I do this my system enters the stand by mode but after an hour or two even when the lid is close position, it wakes up again which I feel is a mall function and need a fix.
    I will also like you to know that as of date I have repeatedly restored the machine to Factory Settings with a hope to fix the above problems but in vain as such I thought of approaching this august forum not only to educate myself as to how the files got corrupt but also to find a permanent fix, if possible?
    Since I am out of USA where warranty facility can't be availed, hence I do look forward to hearing from a guru, who can bail me out!
    Thanking you in anticipation and may God bless you!

  • Fixing corrupted video files

    Hello,
    So an unusual thing has happened to a project I have been working on in iMovie'11. I hope I can explain it properly, since the circumstances seems quite complex (to this layman at least).
    It began when I tried speeding up one of the clips I was using. When I applied this function, it corrupted the project: when spooling through the clips in the project editor, the corresponding video didn't appear in the screen to the right, so I couldn't edit it any more. So I undid the Change Speed edit, shut down iMovie and restarted it, hoping that I could pick up again from where I left off, without the final speed change edit. I have done this a number of times when this problem occurs, and it usually works.
    Unfortunately, this time, the project was still corrupted. In fact, all the projects I was working on, bar one, were corrupted, and I could no longer edit them. I couldn't even go into any of the projects, since the text in the button at the top left saying "Edit Project" was grey and didn't respond to clicks.
    Trying to salvage the project, I removed the New Event folder from the iMovie Event folder in Finder, and restarted iMovie. When it started, I was now able to enter my projects although of course, without any clips in the iMovie Event folder, I could only look at the individual thumbnail clips, and couldn't spool through them.
    I copied the clips from the project I was working on, created a new project and pasted them into that. Then I put the New Event folder back into the iMovie Event folder, and imported another clip. After I did this, I was actually able to work on the clips from my original project in the new project again. It seemed that the clips from my project were linking to the files in the iMovie Event folder, and the thumbnail files too. I thought I'd managed to save the project, but when I restarted iMovie the next day, the formerly working project was corrupted again.
    I know that the clips are there, organised and edited in the way I want them, but I think they are having trouble linking to their corresponding clips in the iMovie Event folder. In the event library in the bottom half, the bits of the clips I am using for this project are marked out in orange lines at the bottom of the thumbnails, as it would with a properly functioning project. So in a sense, the programme "knows" what clips I am using and where, but unless I can edit them properly in the project editor, I can't do anything with it, and certainly can't export it.
    I hope I've managed to explain this problem in a way that makes sense, and will be very grateful for your help.
    Thank you very much.

    I'm having the same problem!
    Help! I don't know how to fix it & have spent so much time on this. I just don't know
    what's wrong! It have many video clips in my project & had noticed that the viewer
    window wasn't playing the events but didn't worry about it. Added more clips to
    my project, photos, music & then POOF! One by one the videos in the project are
    corrupted! Tried re-importing directly into iMovie then reinserting into the project.
    That works but another video will corrupt. Also tried copying project & erasing the
    original. That didn't work!
    To try to fix this I tried erasing the plist file thing that some threads mention. It
    didn't work. All the events are iPhoto videos - does this have something to do with
    it?!
    I don't know what to do & have many, many videos to process. I went out & bought
    FCE (Final Cut Express) to try to continue w/o iMovie but even when I've learned FCE
    iMovie will still have things I want to use!
    Anyone out here have the solution?? Maybe I should re-install iMovie...

  • Fixing corrupt .plist files

    I'm wondering if anybody has figured this out yet:
    Mavericks does some different things with .plist files, and the traditional fix of trashing the .plist that is in ~/Library/Preferences no longer works for fixing a corrupt .plist.
    The .plist files are now cached, perhaps in ~/Library/Caches.
    I found this page that addresses the issue: objective c - Deleting plist file does not reset app on Mac OS 10.9 Mavericks - Stack Overflow
    Out of my own curiosity I tried trashing a .plist file from ~/Library/Preferences and then force quitting the cfprefsd process (mine, not root's), and then restarting, but the .plist file was not regenerated. It remained absent from ~/Library/Preferences. So I restored it from the trash.
    Has anyone figured this out?

    It's a very good question regarding plists generally. You may have seen Apple's mention of it, although the caching seems much more agressive in Mavericks, & eg Safari requires quitting cfprefsd, or a restart (logging out/in isn't enough) for removing/replacing the plist file to have any effect, here anyway.
    In 10.8 and later, the CFPreferences agent process (cfprefsd) will cache information from these files and asynchronously write to them. This means that directly modifying plist files is unlikely to have the expected results (new settings will not necessarily be read, and may even be overwritten). You should use the NSUserDefaults or CFPreferences APIs, or the defaults(1) command, to interact with the preferences system.

  • Need program to fix corrupted video files

    Hello,
    This my first mac and I was wondering if anyone knew of a program that could help me with the following problem...
    I am trying to import videos from my Canon FS100 camcorder (videos are saved on an SD card) and when I plug in the camera to the USB port it can only import one of 9 photos and none of the video. I received a message stating that the files were in an unrecognizable format. I have used the camera and the same brand SD card before and had no trouble importing photo and videos. After about an hour on the phone with APPLE help services last night, the support person concluded that the SD card files had probably been corrupted. Is there a program I can use to fix the files so I can import them to iphoto? I know that the SD card needs to be reformatted before future use but was hoping to be able to use the videos in iphoto and imovie. The file extension of the video file is .MOI or .MOD. I have tried importing directly from the SD card as well but receive the same messages. When I try to import the video clips into imovie, imovie shuts down.
    Thank you for any help!

  • How can you fix corrupt Project Files in Final Cut Pro X?

    Hello All,
    I have reason to believe that one of my project files in Final Cut Pro X is corrupt.
    How may I begin to resolve this issue?  Is there a third party software someone could recommend, like Digital Rebellion (if they have software for FCP X, I'm not sure) that may improve, if not hopefully solve this issue?
    Many thanks!!

  • Fixing Corrupt Video Files

    Hi All,
    So I think I may really be up the river. The other night, I recorded a conference in the DVCPRO 50 codec through Adobe OnLocation to a hard drive. As it turns out, when I try to play the files, I get the error message "this is not a movie file," odd, as I know it is. What puzzles me more, is that each file is large enough that there is clearly something there. I've tried MPEG streamclip and compressor to fix the problem but to no avail. In my research, I've come across suggestions about the hex codes being messed up somehow - but I have no idea about any of that sort of thing.
    If anyone can help, I'd be in your debt forever (figuratively speaking, of course). But seriously, I need some help, and any would be greatly appreciated.
    Thanks,
    Matt

  • Fixing corrupted domain file??

    This afternoon I tried to publish an update to my blog and got the dreaded popup:
    Publishing error - an unknown error occurred.
    I scoured the discussion groups on this topic, checked permissions, tried all 8 steps of Toad's
    suggestion, and still failed.
    I added a new site, constructed a dummy welcome and a dummy blog page, deleted the two existing
    sites and saved the file. (I have multiple WORKING copies of the file on my other machine.)
    Stripped of the two old sites, I could publish the dummy (new) site to a folder with no problems.
    I conclude something is clobbered in my original domain file.
    But, I'm unable to find a recent thread that addressed that issue.
    Since I just finished using Toad's suggestions to get everything working again with iWeb 3.0.2
    on my G4 and MacBook Air, I've learned how to go into "package contents" of the domain file
    and correct the version number.
    What else might I find in there to fix?

    The fact that it opens on the other two Macs points to either the application or you account.  You could reinstall iWeb and see if that helps.  If running Snow Leopard you'll have to delete the current application and all files with "iPhoto" in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/  folder,
    Click to view full size
    Then install iPhoto from the disks it came on originally and apply the latest updater.

  • How to fix a corrupt .avi file (from capture in CS3)?

    So I was recording a VERY long meeting at work and recorded it to my PC via Premiere. Since the recording was unattended, the file size is 275GB! I didn't really think anything would go wrong since I have recorded large .avi files in the past.
    Well when I try to import the .avi or play it in media player, it is saying it is corrupt/wrong file format. I tried a few avi repair utilities and none of them fixed it. I'm guessing the avi headers are missing, but I thought Premiere wrote progressive .avi files (at least their export is progressive and valid while its writing).
    Any help to repair salvage the avi? I only need about 50% of the actual content.

    >wonder why you can view a video that is currently being exported
    Seeing what the computer is
    DOING while it is doing it is really not the same as trying to open a file after the fact
    I have an inexpensive standalone DVD recorder to be able to move a movie from a DirecTv Tivo box in one part of the house to a DVD player in another part of the house
    I can watch the video on the TV while it is playing from the DTivo box to the DVD recorder
    If I do not properly CLOSE the disc when the recording is done, the DVD will not play
    An improperly closed file is, as you found, not going to work
    As I said, my best GUESS is that hitting the full point on the drive caused needed information to not be written to the header (or file end) and now any software you use to try and play or edit that file doesn't know what the file
    IS because the identity is lost
    I will guess that is also why the AVI repair programs you've tried won't work... they need to have some starting information to work, otherwise the contents of the file are just so much random "noise"
