Error Opening Asset

No. All clips used in the project must be online for X2Pro to convert it.

So strange. I closed everything restarted the computer and now it seems to be creating AAFs. The audio guys did say they couldn't open reel 3 for some odd reason. I had to convert project to FCP 7 and export an omf there after trying 3 times in FCP X and X2Pro.

Will X2Pro export an AAF if there is offline media?

The error message is a little misleading; the issue is not caused by file permissions. This page says that error 54 is caused by a "Software lock on file" which means that another process has the file open and has denied any other process access to the file while it has it open.

The error message doesn't give us any information about what process is causing the issue, but may explain why the error happens on different files at different times; if the process that is causing the permission issue has different files open when you try it at different times, the error will happen on different files.

Given that information, do you have any idea what process/application might have had any of those files open when you were getting the error?

This makes no sense. I just finished cutting a feature and I'm trying to create an AAF to send to the sound guys.
I have 4 reels. Yesterday Every reel exported except for Reel 3. Today I can't get any reel to export and nothing has changed. I thought it was a permission issue so I changed all the permission on the hard drive. I also opened the file in quicktime and it played fine. I have no idea what to try now and the audio prep is due now. UGH :-(

ok 30min later I try the same thing and now it exports. Very strange. Attached 2 sample files that didn't export but now they do.
