"Modified Files" .mp4 natives from Sony A7Sii
on Jun 9, 2017 at 3:06:51 pm

Hi! I'm posting this here to see if someone can help me out. I've read other threads but none seem to help me out. I'm using FCPX 10.3.4 and I'm trying to work around using some footage from my new Sony A7SII (mp4 1080p XAVCS). After I import the files creating optimized media and proxies, the event starts working fine but after a while some of the files start showing the red ! Modified Files message. If I close the FCPX and reopen it they appeared fine but then some other files go to the same message.

If I click on reveal in finder it shows me the file just fine, so I don't get why it's showing me this message. Is it something to do with the mp4 files?

Thanks

I have seen this a few times and am not sure what causes it. FCPX maintains internal metadata about attributes of each file, at the time that file was imported. This includes audio channel config, audio sample rate, codec, file size, etc. Upon opening a library it compares that stored metadata to the current file attributes on disk. If any of them differ it shows a red box and says the file was modified.

For a group of files it won't tell you which attributes are the problem. However if you pick a single file and try to relink it, it will then tell you.

Re how to fix this, it may make sense to run Disk Utility First Aid on all drive volumes. BTW any drive with FCPX content should ideally be HFS+ formatted not exFAT or anything else. After that I'd suggest rebuilding Spotlight indexes, since FCPX uses those for file access. It is conceivable some cached or corrupt data in the indexes are causing the problem: https://support.apple.com/en-us/HT201716

Digital Rebellion has a utility called QT Edit which allows editing the file metadata. I've never used it but it supposedly can fix this problem in some cases: https://www.digitalrebellion.com/promedia/

Joe! Thanks for your response. Since I needed to get started with the editing I ended up transcoding all the files to ProRess in another software (even though it increases the file size by a lot) and then imported back to FCPX. I'll try to finish this up, make a backup copy in another drive and then start the process of checking the external drive with Disk Utility and the other tools you recommend.

I'll post something here if it fixes the problem.

Thanks!
