  • Prores 422 file won’t open. I even asked “pretty please”

    Cross-posted in desperation…

    I have a 71.7- gig KiPro recording, MOV Pro Res 422, 720, that seems to be corrupted in some way; I couldn’t open it with FCPX, Compressor, Premiere, MPEG Streamclip, or the can-opener of can-openers, VLC. The memory module’s been formatted and re-used since then, so this is all I have and of course the reason I’m posting is, the content is irreplaceable and I need it.

    With no budget to send the file to some recovery service, can you suggest any free or low-cost tools and techniques to rehabilitate the file? My guess is it is intact but needs “re-wrapping” or a fix in the metadata to make it again recognizable to the edit system. I don’t know how to do that. Any help at all is deeply (and urgently) appreciated!

    I would probably try checking if it’s readable with Mediainfo.

    Hello Mark,

    I’ve had success in similar circumstances using ‘Media Salvage’ and/or ‘QT Repair’ as part of the Digital Rebellion ‘Pro Maintenance Tools’ Kit. Affordable to boot.

    Good luck!

    +1 on the digital rebellion tools. Could be that timecode is gone but with prores files you can often recover up until the recording went wrong. All their tools are great backups for when stuff goes wrong and are very affordable. I wish you the best with recovering your file.

    “Affordable” is a relative term, depending on the budget and level of desperation involved…

    I’ll keep the Digital Rebellion stuff under advisory, but anybody got anything a little… cheaper to try first?

    I’ve pulled Panasonic DVC Pro files back from oblivion with some metadata editing in the file header. I have no idea if that works in your case but it might be a clue as to where to look. If you can compare metadata headers between similar files that play correctly and the ones that do not, you might find a route.

    I have had Panasonic P2 cards not be able to import into FCP and solved it by putting it back into the P2 camera and even though it said there was a problem with the files I put it in playback mode and it rewrapped the footage and then worked on both the camera and in FCP. Maybe put your recording back in kiPro and see if it can be read.

    I think I read that suggestion from Gary Adcock in an earlier thread. Tried copying the file back to a formatted drive module, the module read as 80 percent empty, indicating it knew there was *something* there, but nothing would play out. Still looking for a fix.

    ffmpeg? That’s pretty powerful but not intuitive. The ffmpeg reddit forum has lots of smart people too.
