GH2 File corrupt help

Hey guys,

I've never encountered this before until a few minutes ago. I have a project with roughly half a TB of hacked GH2 footage and it all works flawlessly. I should mention I'm working with Premiere CS 5. I have one clip on two hard drives that plays back flawlessly, but for some reason, once i import that shot into Premiere, the file has the correct duration, but plays back the first second of a random other clip over and over and over again with strange pixels going on in the top left corner, reads as just a video file without sound, and reads as 29 fps....

So, the file on the drive is fine, but the second that single file is imported, for some reason it's all haywire. Anyone encounter this before? It's quite important I find a solution to this as the shot is vital to the project.
 
Is is a screenshot of what I'm trying to describe. However, this time, it loaded as a green shot instead of looping the first second of a random clip.

And again, the file on the hard drive plays back just fine. Just not in the editor.

Sounds like some kind of metadata screw up in Premiere. I think you can clear out your cache files. Have you tried creating a new project and import just that one clip and see if it's fine there?
 
I gave both a shot and neither one fixed the issue. I did, however, run the one file through 5DtoRGB that gave me something I could work with. I would still really like some suggestions as to what happened?
 
looks like a corrupt file - I've had the same thing in Edius where I've recovered a file from the card (the green start & end - not the random clip thing). Iis there another NLE that will read it? - if you can find a program or utility and convert it to AVI or MOV maybe you can import it that way
 
If the file is corrupt then why does windows have no issue opening it and playing it back?
 
Hmm, have you tried restarting your computer? Or maybe unplugging the computer for 10 seconds and plugging it back in? I kiiid. But this is very odd. Maybe try renaming the file. See if that works? I don't think the file is corrupt, but I do think that it recorded at a particular odd bit rate and premiere doesn't know how to decode it. If you do figure it out, let us know!!! More times can I count that the OP finds a solution, and never shares it.

I tried those things and nothing worked. Very odd. My solution was still transcoding it through 5DtoRGB, but really doesn't answer the question as to why this happened.
 
Couple of questions:

1. When you copy the files off the card to your HD, do you copy the whole directory structure (do you copy the whole contents of the BDVM, AVCHD, or PRIVATE folders or just the MTS files)?

2. Is Premiere reading this metadata? An easy way to tell is to right click the clip in the file bin and see whether or not "Analyze Content" is greyed out. If it is grey, Premiere is not reading the file's metadata. This will always be the case if you answered no to question #1.


Now, if you do copy the directory structure, try making a copy of the MTS file alone, away from the metadata, and try importing that.

If you do not, try making a copy of the MTS file and putting it by itself in a folder, and run a checkdisk on that folder. If it finds errors and repairs them, try importing that corrected file.

I probably don't need to tell you, but IT IS IMPORTANT TO DO THESE TESTS ON BACKUP COPIES AS THEY COULD MAKE IRREPARABLE CHANGES TO THE FILE.

If that fails, search for the Panasonic AVCHD repair tools. They will rebuild certain files and directory structures. It's been a while since I have had to use them, so I can't remember all the things they can and can't do, but they do do some repairing of corrupt files.
 
I generally always just open up "Stream" and copy and paste the files into my folder. You think this might be the reason? Even so, it's still strange how it plays fine in windows.

Thanks for your help!
 
I'm not sure. The only difference I've noticed is in whether you can analyze content, which I don't do anyway (for speech recognition and what not) but that's a sign that Premiere seems to like it a little better. No, the first thing I would do is make a backup copy and run checkdisk on it and see what it finds.
