  • Session File Corruption in Sony Vegas Pro 9.0 64bit

    Posted by John Bires on February 4, 2010 at 6:39 pm

    Hey All,

    I have been using Vegas Pro 9.0c 64bit for the last 8 months or so without this issue, so I am wondering if maybe the group can shed some light on it. I am running a Quad Core system, Vista 64, 8gig RAM, Asus Commando Mobo, and using some WD 1TB drives connected to my Serial ATA on the mobo.

    I recently went back to open up some old projects that I had edited in November and December and when I looked on my drive, the session files had 0KB in their size. I had recently done a disk defrag on all my drives, but I hope that isn’t the issue. Sessions I had created previous to these projects and sessions created after these projects all seem to work fine. When I try an open them through the Vegas Open Dialog Window, I get descriptions in the bottom of the window that say “Unknown format” or “Stream attributes could not be determined”. Only one of the files that lists at 0kb actually has a Bak file associated with it, but without the source veg file I am not sure how to recover that bak file.

    Has anyone ever seen their session files turn into 0kb uknown files. Also the files are still maintaining the Icon flag as a Sony Vegas Project file.

    I have done the Ctrl-Shift Startup thing to clear out my caches and default the app.

    Just looking for some clarity here.

    Thanks!
    -John

    I’ve just a similar problem after defragging last night I get up and open Vegas 9c and many of the audio sound effects I had in my latest project went from .wav audio to .sdk files and not even sure what that means except they have been corrupted. The only thing I have done since yesterday is the defrag. I would like to know more abou this because I put a lot of effort into getting the correct sound effects and not happy losing them.

    Vegas creates .sdk files when it opens an audio file. It does nothing to the .wav file. So, your files have not been converted, but I have no idea where they are. I never run a defrag unless my system is backed up. That means I can recover if the defrag goes awry. What defrag program did you use?

    I used Defraggler program to defrag system. I just realized this posting says 64bit and I’m using 32bit Windows 7. Yes the only files that changed to .sdk were audio files but the originals disappeared. I got multiple prompts to relocate these when I reopened the project and a few I found (all in sound effects folder) and some were gone. Just vanished

    To repeat, Vegas does not “change” audio files to .sdks. It creates a second file, with the sdk extension, when it processes an audio file. It does not move, delete, or change the original audio file.
