UNF Files

Hi Ben,

I found a couple of old (from last year) UNF files in a backup. I've tried fixing them with Movie Fixer and it immediately stops and indicates a message box of "There was an error processing the file. Error code: 110,73". I get this message on both the UNF files I'm trying to fix.

Also, these files are from the same camera, one day after the other. Any idea on what may have caused this to occur?

Is there any other way you know of to fix these files? Maybe try recompiling them with Quicktime?

Please Advise,
-Scott

    Hi Scott,

    There is no one reason why this could happen - anything that interrupts the recording could cause this (e.g. power outage, software crash, force quitting SecuritySpy etc.). That error from the Movie Fixer indicates it couldn't find any frames in the file - how large are these files (use the Get Info option in the Finder to find out)?

    Thanks for the quick response Ben.

    One file is 4GB and the other is 6GB.

    Are there any third party tools that might be able to help me?

    Thank you in advance for your exceptional service and help with this!

    Hi Scott,

    If you have a way to send one of the files to us (e.g. Dropbox/WeTransfer/Web download etc.) we'll take a look to see if we can improve our Movie Fixer app to cope with it. I don't know of any other tools that you can try, sorry.

    Ben,

    The video fixer eventually did fix both the files when I tried it on another MAC. The new video file kept stopping when played in QuickTime until I did an export through QuickTime and then everything seemed to work fine.

    Do you know if your Video Fixer or the QuickTime export could have caused any loss of frames or other abnormalities in the file? I'm just wondering how reliable these files are since they have been fixed by the video fixer and exported through QuickTime Player.

    Hi Scott,

    Good to hear you managed to fix the files. The Movie Fixer should find all the frames (it scans through all the data in the file byte by byte, so shouldn't miss anything). However the export from QuickTime Player may have got rid of some frames, depending on the export settings. If there is anything of particular importance, I suggest you open the fixed version of the source movie file in QuickTime Player, jump to the part you need to view, and use the left/right arrow keys to step backwards/forwards frame by frame to view what is happening.

    The other thing is that the timing information will have been lost, so the movie will play back either slower or faster than real-time.
