    Hello,

    I'm new to this community and I wish you could help me with a video I recently downloaded.

    The video is 900Mb and 1h04 duration but when I went to play it, it freezes at 00:12:33. Tried VLC, WMP, Media PLayer Classic. When I open it with VLC a message appears that the file is broken...and offers tyhe option to repair it or not. If I choose don't repair i could watch only the first 12 minutes and if I let it repair it starts to do the job but hangs at 19%

    I then tried opening it with VirtualDub. It starts reconstructing the missing index block...Takes about 20 minutes to go through the 900Mb but then it recognizes only 22575 frames/12 minutes. Closed it and reopened it with VD checking the option "re-derive keyframe flags" only. Result; 12 minutes. Reopened again with VD with the options "re-derive keyframe flags" and "Open in AVIFile compatibility mode" checked. Result: a freezed VD.

    Same thing with VirtualDubMOd.

    It then occurred to me converting the whole avi using Total Video Converter. When the converted file reached 124Mb I opened it with VLC hoping I've got some 20 minutes video. Result: 0 duration.

    The surprise was when I used GSPOT: no codec problem but it says: Video 157Mb (17.5%). Audio:17.2Mb (1.92%) and AVI Overhead: 725Mb (80.58%)

    Last I tried AviMedic. It says that there is about 17% real data and 83% fake data??


    These are the results from MediaInfo and GSpot

    Is this a hopless situation? Thanks

    I would normally say that sounds like a trick some fake uploaders do. They just present a few minutes of video and the rest of the file is padded with junk. But that appears to be an older video. Maybe just a corrupted file. I suspect there is likely no way to repair it. You could open it in something like VirtualDub's Hex Editor. I suspect you may see a lot of zeros if anything past the initial 12 minutes shows.

    Gspot is telling you there is only around 150mbs of video data ... either the downloaded file wasnt processed prior to completeion or its a dud file ... choose your sources more carefully.

    Thanks for your replies and advice. I think that something went wrong during the downloading of the file because I don't see why someone would fill with junk a video of a movie of the 50's few are interested in.

    I will try to download it again and let you know.

    Did you download it from a torrent? if so, you should be able to get the torrent program to do a hash check.

  6. Your file was messed up during upload or download. I did a search and found what appears to be the exact same video -- same size, codecs, frame size, etc. It had no problems.

    No, that was downloaded from a filserve.com, direct link.

    Thanks jagabo, I was desperately looking for this movie and found no other places to get it other that on filserve, so it is the same file.

    Hi, you know what is the real problem here.
    The FILESERVE MANAGER, I downloaded two files (videos.avi) using it and none of them work at all, It doesn't matter the player I use to watch them.
