    Two impossible files to import from P2 card

    I've waisted days trying to import all my files from my P2 card to MC.

    There are 23 clips in my card, 21 are easily added to the bin and have no issues.

    Two of the clips are being ignored by MC. Either I try to import the P2 card or use AMA or try locating them with the Media Tool, these two files are never added.

    I've tried with MC 5 and 3.5. I've tried to figure out whether the two clips are corrupt, but there is nothing  suggesting that. The mxf info/text file gives me no relevant information I can use to locate the issue.

    The clips are above 4 GB, but there are two other files with the exact(!) same size that are working fine.

    In a new user to MC, but I've spent days reading forums and manuals but I cant figure out how to force MC to let me add the clips to a bin and have them played.

    Anyone want to help me?

     

    Camera: Panasonic HVX-201 (the camera wont play any of the files, perhaps because I manually moved the CONTENTS folder from the card to my pc, and back again).

    Format: 720P/25 (All files in the card)

    Card: Maxell 64 GB P2

    What if you copy the files at the hard disk and try to link them from there?

    Re: Two impossible files to import from P2 card

    A few questions/ideas: 

    1. are the files in good-enough shape so that you can play them back in your P2 camcorder? If no, you may just have bad files.

    2. If so, can you not use the "link to AMA files" item in MC5 to get clips from those files into a bin?

    3. If no, copy the troublesome video files (from the contents/video folder on the P2 card) and their associated audio files (from the contents/audio folder) into a new folder on your hard drive. The filenames make it obvious which audio files are related to the video. Try to link to them using AMA. If no go, turn off AMA in the AMA settings and restart Media Composer. Now try to use import P2 under the File menu.

    4. If still no-go you're in terra incognita for me. I'd get an MXF unwrapper (e.g. http://www.mog-solutions.com/produtos.php?ID=110&ft=1) and try to squeeze out the video and audio from their MXF skin.

     

    Good luck.

    Re: Two impossible files to import from P2 card

    It doesn't seem to let me add files from the hard drive. I've tried the import-function, but it says the media can't be imported directly to the bin.

    The files in the P2 card have gone from another P2 card to the hard drive, and are now on a similar P2 card. (Needed to empty the original card so I save the CONTENTS folder to the hard drive). I hope there arent any other hidden files that need to be moved along with the contents folder, but it would explain why none of the files will be played back on the camera - including all the files that easily are imported from the P2 card and to the MC bin.

    1. None of the files can be played back in the camcorder

    2. Linking to AMA files works with all files except these two files.

    3. I've tried copying the two files to the hard drive an importing P2, also tried AMA, didn't work

    4. The MXF-unrwrapper was expensive! Any cheaper solutions?

     

     

    Could an explanation be that the two files are a split made by the camera because it was the longest clip I did? Since the camcorder then splist the clip into two files (possibly) I might have lost some metadata when moving the contents folder to the hard drive, and therefore MC won't let me add these files?

    In that case, is there anything I can do to save this?

    "... so I save the CONTENTS folder to the hard drive). I hope there arent any other hidden files that need to be moved along with the contents folder ..."

    did you forget the LASTCLIP.TXT file?  You may have screwed the pooch without that file, especially if your troublesome files are "spanned." 

    I don't know the cost of MXF-unwrapper, how much is your time and you footage worth?

    Re: Two impossible files to import from P2 card

    Of course you have a point there Craig. The footage is invaluable, my time is wasteable.

    That being said, yes...I forgot the darned lastclip.txt file. Doesnt that contain only a single filename? I'm thinking it should be possible to write a new lastclip-file? It would definetly be cheaper than the MXF-unwrapper. I would also learn more doing it this way.

    It was appr. 190 EUR for the unwrapper.

    It would really appreciate any manual and free ways of making the files readable for Avid...That editing software wasnt cheap...

    Re: Two impossible files to import from P2 card

    Wouldn't it be possible to recreate a LASTCLIP file?

    Re: Two impossible files to import from P2 card

    Probably. You'd need to know, of course, which clip was the last one recorded on your card. I've never wrestled with this particular problem so I can't give much much more technical help.

    There's some info (not sure how good) here:  http://dvxuser.com/V6/archive/index.php/t-58755.html

    Re: Two impossible files to import from P2 card

    Can you play the two files with the free Panasonic P2 Viewer software or P2 Contents Management Software?  If not, the files are probably corrupt and there's probably no way you'll be able to use these files in MC.  To Check if the files are the last 2 recorded, simply go into the Contents//Video folder and view by Date Modified.

    Also, are you positive that the media did not span across multiple cards?  In my experience, the LASTCLIP.TXT is not necessary to successful import or AMA linking, even across spanned cards.

    Re: Two impossible files to import from P2 card

    I'll have a try with the P2 viewer. And I'll check whether these are the last files tomorrow. Though I am afraid that the most likely reason for the files not working is that they might be corrupt.

    I only used 1 P2 card because I was afraid of any issues because of spanning across cards...

    Re: Two impossible files to import from P2 card

    Hi guys!

    Seems it has nothing to do with the Lastclip file, nor are the files corrupt. What I finally figured out, after several weeks, is that these two large files are part of two other files in the card.

    In other words, I have 4 huge clips in the P2 card. Two could be played, imported and converted. Two wouldnt open in neither P2 viewer nor in Media Composer. By coincidence, I played these two troublesome files in Windows Media Player (possibly a new codec during one of several installations of software), and the files could be played - though in 4:3 aspect.

    So it turns out that the HVX201 camera cuts long recordings/clips in several files to keep the file size below 4 GB. So when importing into P2 viewer or MC, these files are read only as one file/clip, by the name of the first file.

    This was new to me...
