II am using Lightroom Classic 13.5.1  to manage my photo collection . I have a problem witha couple of  thousand JPG photos I made a long time ago with my SONY RX100-I (~30% of the total amount ) when writing tags to them from lightroom  (it can read them) it gives error  "cannot write metadata - unknown file format"   . I have tried exiftool to repair the metadata , but that does not help. If I open and safe the JPG in photoshop, the error disappears. But that is an elaborate process with image loss. Please find attached a sample file with write issues . What is causing this ? Is it a lightroom bug or can I delete a specifi tag causing this?

Just upgraded to 14.0.1 but the problem stays the same :  "cannot write metadata - unknown file format"  on many RX-100 JPG photos

I see the same error with your sample file. 

 

I tried some JPEGs from my Sony RX-100 I, taken in 2012, and they don't have that problem.

 

Looking at your JPEG with Exiftool, I see that you've modified the XMP metatadata with Exiftool 12.57 (that from 2/23/2023). When I do "exiftool -xmp:all=" to delete the XMP metadata from the photo, LR is able to do Save Metadata To File without problem.

 

This suggests there's some incompatibility between LR and the changes made by Exiftool. Do you have any images exhibiting the problem that you haven't modified with Exiftool?

Hi I use a tool called geosetter to geotag all my photos and it uses exiftool internally . All photos I have have gone through this workflow, but only limited once have this problem (esp the Sony RX100-I but I also noticed some problems with a few Canon originating photos. They are from third parties though, I never owned one , so the vast majority is with the Sony ones). I wil try a few withremoving everythign and letting them written back by lightroom . If that works I will have to find a way to script the list coming from lightroom to execute this command on
